Accsense Monitoring System FAQ

Security

Can I trust Accsense with my data?

The Accsense servers are located in managed hosting facilities who provide a 100% uptime guarantee. Data is transferred to the servers over the internet using the industry standard SSL/TLS protocol, ensuring 128bit encryption and verifying that both the sending gateway and the receiving server are genuine. All servers are safeguarded with completely redundant drives to guard against catastrophic hardware failure. Physical [[security]] is maintained through locks, access controls, and biometric surveillance systems. To protect information from outages, HVAC, fire suppression, diverse power feeds and hot-swappable servers and routers stand on guard. Additionally, daily backups are performed and are kept in environmentally controlled secure vaults, away from the servers.

 

Will my data be backed up?

The first level of data security is provided by the near instantaneous replication of your data, with a copy being persisted both on the receiving Accsense server and within the data storage backend. The hosting facility then performs daily backups of all our data stores, securing your measurement data in a location that is physically remote from the Accsense servers.

 

Will Accsense interfere with existing wireless equipment or WiFi?

The quick answer is, No, the system will not interfere. Accsense communication protocols were specifically designed to co-exist with other wireless systems without interference. This good neighbour policy is an integral part of an Accsense Fast & Easy system deployment. For more detailed information, read our Wireless Coexistence Document.

 

Gateway

What are the differences between Data logging rate and Alarm sampling rate?

The Sub-Sampling feature allows users to designate separate time intervals for alarm-checking and data logging. For example, a user can save data four times a day while checking for an alarm condition every five minutes. This simplifies data logs while allowing users to check for alarm conditions more frequently.

  • Data Logging Rate lets users to choose the frequency data is logged in Gateway. Click the drop-down menu, choose the rate, and click “apply.”
  • Alarm Sample Rate lets users determine the frequency in which the system checks for alarm conditions. Click the drop-down menu, chose the rate, and click “apply.”

Alarm Sample Rates are more frequent than the Data Logging Rates so users are alerted of alarm conditions more rapidly, but do not have to store an overabundance of data.

NOTE: Once an alarm is triggered, the Data Sample Rate increases to match the Alarm Sample Rate to document the alarm measurement data. The sampling rate increases as the alarm triggers, and once the measurements resume normal limits, the Data Sample Rate resumes.

 

 

Can I change the display name of the Gateway?

Yes – in the Gateway Preferences the system administrator will be able to change the Gateway name.

 

Can I hide the some of the sensors displayed?

Yes – In the Gateway Preferences under the View tab there are 3 options Visible, Hidden and Disabled for each probe.

  • Visible Readings are displayed and recorded
  • Hidden Readings are recorded but not displayed
  • Disabled Readings are not recorded or displayed

 

Can I connect multiple gateways on a single login account?

Yes – contact your local Accsense dealer with the MAC addresses you require under the same login.

 

My gateway’s error LED is flashing RED.

The gateway has detected an error. The most common reason for this is that the gateway is unable to communicate with the Accsense servers. See ‘My gateway isn’t connecting to the Accsense Server’.

 

My gateway’s error LED is solid RED.

The gateway has failed its internal diagnostic check. Disconnect the power from the gateway, wait sixty seconds, and plug it back in. If the problem persists, contact your distributor for a replacement.

 

My gateway isn’t connecting to the Accsense servers.

Verify that the Ethernet connection is working properly. When the RJ-45 connector on the back of the gateway is plugged in, a green link LED should illuminate on the port.Verify that a DHCP server is present on the network. By default, the gateway does not have an IP address, and requires a DHCP server to function properly. A static IP address can be applied with the Accsense Remote Gateway Configuration Tool, available in the Support->Utilities section.

If the Internet connection is behind a firewall, ensure that the gateway can make outgoing connections on the https port (TCP port 443). If your network uses a proxy, the gateway must be given direct access to an outgoing connection on this port. Consult your network administrator for more information on Proxy Server and Firewall configurations.

 

I can’t associate sensor pods with my gateway.

Ideally, when associating pods, the sensor pod should be within 10 feet of the gateway with a completely unobstructed line of sight. Ensure that the antenna on the gateway and the antenna on the pod are firmly screwed in place and free from physical defects.Tap the Associate Button, located on the back of the gateway. When pressed, the Radio LED on the gateway should rapidly flash for approx. 60 seconds. If the Radio LED does not illuminate, the gateway is most likely having a problem connecting to the Accsense Servers. Refer to the My Gateway isn’t Connecting to the Accsense Servers section.

Hold down the Associate Button on the sensor pod for 4 seconds. The Associate LED on the pod should flash rapidly for approx. 60 seconds. If the Associate LED on the pod is not flashing, power cycle the sensor pod (hold down the power LED for 2 seconds) and try again.

 

How can I set a static IP address on my gateway?

This requires the Accsense Remote Gateway Configuration Tool, which allows the gateway’s configuration to be modified. This is available in the Support->Utilities section.

 

Alarms

What defines an alarm state?

Alarm states are user defined. You may specify a greater than, less than, or both values allowing measurements above a value, below a value, or within a range to trigger an alarm.

 

How do I know if an alarm is enabled?

If an alarm is enabled, the alarm icon will appear green or red (if triggered).

 

How do I enable an alarm?

Click on the grey alarm icon and then under the General tab of the Alarm Definition window tick the “Alarm Enabled” box.

 

How do I configure an alarm?

Alarm Limits

  • Sensor Value: Set the value the alarm will activate at and whether it should be Greater Than, Less Than or Equal To this value.
  • And/Or: Logical connection for the sensor values (optional), this opens up a secondary sensor value.

Advanced Trigger mode- Configures how the alarm will trigger

  • One-Shot: When the trigger condition occurs, the alarm will not trigger again until the user logs on and sends the alarm to “history.”
  • Auto-Rearm: The alarm can re-trigger each time the measurement value matches the trigger alarm limits. A re-trigger will only occur if the measurement has first returned to a non-triggered state. (e.g. Measurement Value does not match the trigger alarm limits.)
  • Filter: Indicate how many times a trigger condition must occur before actually triggering the alarm.

 

How do I receive alarms?

Notification of triggered alarms can be sent to your email, via a text message, or by a voice message to your cell phone.

 

What is the difference between Default and Custom Alarm Contacts?

Default Alarm List: Accsense’s software includes a “Default List” option under the Notify List. Users enter default contact information once, under System Settings and apply information to all alarms.
Custom Alarm List: Accsense’s software includes a “Custom List” option under the Notify List. Users can enter different contact information for each alarm when using this.

 

How do I send a text message to my cell phone?

Most major US Cellular carriers assign an email address to your cell phone. To receive an SMS text message, enter an email addresses of your carrier into the alarm definition. For example:Nextel: [phonenumber]@messaging.nextel.com

Where [phonenumber] is your 10 digit phone number (without the brackets). Click here for a list of SMS gateways.

 

What are Voice Notifications?

Voice Notifications are a way for you to receive alarms through a standard telephone or cellular phone. When the alarm is triggered, our servers will call the listed recipient(s) and a digitized voice will read off the content of the alarm message.

 

How does Sequential Alarming work?

Sequential alarming can only be set if the User has a level 3 account and is using the voice alarm notification. Sequential alarming can either be set in the Default Alarm Contacts or the Phone Lists for each individual sensor.Each phone number on the list will be dialled in sequence until a response has been received that a recipient is going to take responsibility for the alarm notification. The user takes responsibility for the alarm by pressing 5 in response to a call from the Accsense server. The phone list will be repeated twice if no user takes responsibility for the alarm.

 

What does the Voice Alarm say?

This is the exact script the Accsense notification service will read to you:This is an alarm notification from your Accsense wireless monitoring system.

The [SENSOR NAME] sensor on Pod [POD NAME] reported a [ALARM NAME] alarm at date/time, in, UTC time.

The data value is: value

I repeat, the [SENSOR NAME] sensor on Pod [POD NAME] reported a [ALARM NAME] alarm at date/time, in, UTC time.

Please login to your Accsense account at www.accsense.com for details.
——–

All [BRACKETED] values are read from the user-configured settings for each pod. If you change the name of a sensor or pod, it will be read in the message. All bold values are read from the actual stored data that triggered the alarm, which may not be the most recent data point.

In the case of a filtered alarm (X occurrences in Y samples), the alarm will read off the time stamp and value of the most recent data point, the one which triggered the alarm.

 

Wireless Sensor Pods

How do the sensor pods communicate?

Wireless sensor pods form a mesh network in which information can travel through many, redundant paths. When necessary, pods will automatically “route” or “piggy back” their data across pods with stronger signals. This mesh system significantly increases reliability and range.

 

How often do sensor pods record measurements?

Wireless sensor pods can be configured to record data from every 30 seconds to once a day.

 

How far can sensor pods transmit?

Point-to-Point, sensor pods can transmit approximately 80 meters outdoors. But, since our Accsense Solution automatically forms a “mesh”, messages can piggyback from pod to pod. Consequently, Pods can in fact be much further than 80 meters from the gateway.

 

How many sensor pods can communicate with the gateway?

Up to 16 pods can be supported by one gateway.

 

What happens if a sensor pod cannot reach the gateway?

In the event that the wireless connection between a sensor pod and the gateway is unavailable (the gateway is powered down, a pod relaying the message has run out of batteries, etc.), the sensor pod will retain up to 255 data points. During this time, the sensor pod will try to re-establish communication. Once communication has been re-established, measurements will be posted to your Accsense online account.

 

How are sensor pods powered?

Sensor pods can be operated by three AA batteries, by an external battery pack, or by a 100-240 VAC power adapter. Accsense recommends that users always keep AA batteries in sensor pods as a backup to AC line power.

 

What is the battery life of the sensor pods?

Battery life is dependant on the frequency of collected measurements and external sensors. Higher measurement intervals mean higher battery life. An increased use of external sensors can reduce battery life.

 

Can I use rechargeable batteries to power my sensor pods?

Yes, but note that batteries will NOT recharge inside a sensor pod, even on external power.

 

Can I add more sensor pods after the initial purchase/setup?

Yes. Additional pods can be added into a system at any time with the push of a button.

 

Is there a difference between repeater pods and senor pods?

No. All pods are take measurements and repeat one another’s signals.

 

Online Account

I can’t log into my web account.

The gateway may not be contacting the Accsense Web Servers. Check the status LED’s on the gateway, and verify that the error LED is not on. If it is on, proceed to the My Gateway’s Error LED is Flashing Red section, or My Gateway’s Error LED is Solid Red.Verify that you are attempting to log in with the correct gateway MAC. The MAC address is printed on the silver label located on the bottom of the gateway.

Verify that you are using the proper username and password. The default username is Admin and the default password is also Admin. The username and password are case-sensitive, so make sure to use a capital ‘A.’

 

Can I print a measurement chart?

Yes. You can print measurement charts by right-clicking on the chart itself. When the menu appears, select the print option. With Internet Explorer, you may have to left-click first, and then right-click.

 

How many data points are displayed on the measurement charts?

360. If your chart duration is only a couple of hours, then all of your data will be displayed. However, with a very large chart duration (representing more than 360 data points) you will see a footnote appear under the lower right hand of the chart to signify that the data you see is condensed to fit on the screen. Without boring you with the mathematical details involved, even though the data is condensed, it is done in such a way that any anomalies (or spikes) will still be viewable. Use the custom duration settings (in the drop-down drawer under the chart) to zoom in on any area of interest that you want to inspect in full. NOTE: the values in the Data Table tab is always the complete data set and are NEVER condensed/filtered.

 

What is the difference between an Administrator Account and a Read Only Account?

An Administrator Account allows the administrator the rights to change coefficients, configure alarms, etc. A Read Only Account only allows the user to view graphs, observe settings, etc. A Ready Only user cannot change any settings or information.

 

What do I do if I forget my login or password?

If you forget your login or password, Accsense can retrieve your login, and set up a default password, then you will need to set a new password.

 

Why do my readings change when daylight saving time is applied?

The Accsense database contains each sensor reading associated with a timestamp that is relative to UTC (Coordinated Universal Time). There are no gaps or duplicate readings caused by changes in local timezone or by daylight savings.However, confusion can arise when viewing reports of this data via the Accsense web interface. This is because the web page presents the timestamps adjusted to your local timezone (as set in your Account Settings). If your selected timezone is subject to seasonal daylight savings time adjustments, then the timestamps you see in your reports will also be subject to this adjustment.

For example, if have an account timezone set to “(GMT) Greenwich Mean Time” then the dates seen will be localized to Europe/London, including the application of daylight saving time. This means that a viewed report in June 2010 for May 2010 the data may show a reading of 23.67 reported at 03:00:00 on the 23/MAY/2010; but generating the same report in November 2010 would show 23.67 reported at 02:00:00 on the 23/MAY/2010 (since the local clocks will have gone back 1 hour).

To work around this problem the account can be set to a timezone that is not subject to daylight savings. This can either be a permanent change or, if localised times/dates would rather be seen, then change to a non-DST timezone immediately before downloading the data and immediately back after the download.

For example, to see all dates localised to UTC (no daylight saving) the account can be set to timezone “(GMT) Coordinated Universal Time”.

To set a timezone so that it does not take into account daylight saving, the timezone in the account settings needs to be changed to a timezone that does not have DST abbreviated next to it.

 

Can I display more than one set of sensor readings on a graph?

Yes – select the graph icon for the gateway “Multi-Sensor Chart”. From the Gateway(s) shown highlight (using Ctrl key) the sensors readings to plot on to a single graph. Then click on Draw Chart.

 

My graphs aren’t displaying when using Internet Explorer 8?

Microsoft has altered how Internet Explorer renders some flash content in Internet Explorer 8 and above in Windows Vista, 7, and 8. To fix this, you must put Internet Explorer in Compatibility Mode. To do this, simply press the [ALT] key on the keyboard, and you’ll see a series of drop-down menus appear just below the address bar (File, Edit, View, Tools, etc.). Click on the Tools menu. Choose Compatibility View Settings, and then click the check box next to ‘Display all websites in compatibility view’, then click ‘Close’. This will permanently fix the graphing issues. Read more about it in detail.
