Security
| Can I trust Accsense with my data? |
The Accsense servers are located in managed hosting facilities
operated by Rackspace 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,
Rackspace performs daily backups that are kept in environmentally controlled secure vaults, away from the servers.
[back to top]
| 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. Rackspace
then performs daily backups of all our data stores, securing
your measurement data in a location that is physically
remote from the Accsense servers.
[back to top]
| Will Accsense interfere with my 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.

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.
[back to top]
Notification of triggered alarms can be sent to your email or via a text message to your cell phone.
[back to top]
| 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 one of the following email addresses into the alarm definition.
T-Mobile: [phonenumber]@tmomail.net
Virgin Mobile: [phonenumber]@vmobl.com
Cingular: [phonenumber]@cingularme.com
Sprint: [phonenumber]@messaging.sprintpcs.com
Verizon: [phonenumber]@vtext.com
Nextel: [phonenumber]@messaging.nextel.com
Where [phonenumber] is your 10 digit phone number (without the brackets).

| 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.
[back to top]
| 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.
[back to top]
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.

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.
[back to top]
| How often do sensor pods record measurements? |
Wireless sensor pods can be configured to record data from every 30 seconds to once a day.
[back to top]
| 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]].
[back to top]
| How many sensor pods can communicate with the gateway? |
Up to 16 pods can be supported by one [[gateway]].
[back to top]
| 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]].
[back to top]
| How are sensor pods powered? |
Sensor pods can be operated by three AA batteries 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.
[back to top]
| 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.
[back to top]
| 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.
[back to top]
| 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.
[back to top]
| Is there a difference between repeater pods and senor pods? |
No. All pods are take measurements and repeat one another’s signals.
[back to top]
Online Account
| 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.
[back to top]
| 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.
[back to top]
| 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.
[back to top]
| 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.

[back to top]
| Why is my RTD sensor reading 590°C at room temperature? |
If you install a 1000 ohm [[RTD]] instead of a 100ohm [[RTD]],
the system will read approximately 590°C when the probe is at room temperature.
