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.
