DSC PG9905
Wireless PowerG Temperature Detector
Description
The DSC PG9905 is a wireless temperature detector that works with PowerG-compatible alarm systems. Upon sensing an unusually high or low temperature, the device will activate and send an alert to the system. It can be used in an indoor or outdoor environment to monitor the temperature.
There are many reasons why a user would want to use a temperature sensor with their system. In the winter, a broken heater could cause the pipes to freeze. This could cause serious and expensive damage. But the PG9905 will alert a system before the indoor temperature reaches these dangerously low levels. The user can then take action before this occurs. The sensor can also be used to monitor for unusually high temperatures that can be caused by a broken AC unit. And with an optional temperature probe, the device can also be used in an outdoor setting.
As a PowerG Sensor, the PG9905 features some highly impressive functionality. It can send alerts to an alarm system from up to 2 kilometers away with a clear line of sight. This means that the device can easily be used on another part of the property, such as in a detached garage or in a barn. And since the device uses 128-bit AES encryption in its wireless communication, it is next to impossible for others to hack or takeover the device.
NOTE: The maximum range for a PowerG Sensor when used with an IQ Panel 2 Plus System is only 2,000 feet in open air. This is considerably less than the advertised 2km range. The 2km range refers to when a PowerG Sensor is used with a DSC PowerSeries NEO System.
NOTE: Unfortunately, there is no way to receive high/low temperature alerts for this sensor from Alarm.com. The only way to receive temperature alerts from Alarm.com is by using a thermostat, such as the ADC-T3000. Update: This was later fixed in Qolsys IQ Panel 2 Plus Firmware Version 2.5.0 by setting the PG9905 to Sensor Group 25 - Non-Reporting. More information can be found here.

The DSC PG9905 PowerG Temperature Sensor is designed to detect unusually high or low temperatures in a home or business. This is important for detecting a broken HVAC system that could otherwise result in serious damage. The DSC PG9905 PowerG Temperature Sensor works quite well at detecting temperatures and alerting a compatible system. We give it a 5 Star rating.
There are many things to like about the DSC PG9905. For one, it has an adjustable temperature setting that you set at the system. This way, you can choose the high and low temperatures that will alert the system. The temperature values you can set range from 0 degrees Fahrenheit to 999 degrees Fahrenheit, so you will certainly be able to choose an alert that works for you. Our technicians have found that the sensor works very well in reporting high and low temperatures to the system. You also get all of the great PowerG features with this sensor. It can be used with a system from up to 2 kilometers away with direct line of sight. It also uses 128-bit AES encryption for enhanced wireless protection and security.
There are some downsides to the PG9905. For one, it is for indoor use only, unless you add a separate temperature probe. This probe would need to be purchased and added separately. Another downside is that Alarm.com will not send out high/low temperature reports for certain panels. This is not the fault of the PG9905, but rather a limitation of Alarm.com. This was eventually fixed on the Qolsys IQ Panel 2 so that Alarm.com would send out reports, but users of others panels may run into problems. But overall, the PG9905 works really well as a temperature sensor, and it performs its job effectively. It gets 5 Stars.
Good: Adjustable Temperature Setting, Reliable Reporting, Excellent Range, Encryption
Bad: Needs Probe for Outdoor Use, Alarm.com Does Not Send Temperature Sensor Alerts for Certain Panels
Bottom Line: 5 Stars
