The DSC PG9905 is a wireless PowerG temperature detector for both indoor and outdoor applications. The PG9905 is ideal for residential and commercial installations where running wires is either difficult or impossible. The PG9905 detector monitors indoor room temperature using an internal sensor. For outdoor or refrigerator installations, a waterproof temperature probe (optional) is used.
The PG9905 can be used in instances where temperature detection is critical. The temperature information communicated from the PG9905 to the control panel can also be displayed on the system keypad. Use the PG9905 when activating and deactivating pipe heaters at locations where low temperatures may cause the water in pipes to freeze. Warn of possible electrical device malfunction due to high or low temperature levels. Alert elderly people of a significant rise or drop in room temperature.
Based on the configuration, once a chosen temperature point has been reached, the control panel generates an alarm or warning message, and sends a notification to the GeoArm central station, and if configured, used the PGM controls to switch on a connected appliance (e.g. a heater or an air-conditioner). When the temperature returns across the configured threshold, a restore message is generated.
When using the PG9905 temperature probe, temperature measurements are only performed by the probe sensor. When the probe is not connected and its terminals are shorted, the temperature measurement is performed only by the detector's internal sensor. For further reliability, the PG9905 tamper switch is activated when the detector cover is removed. Operating power is obtained from an on-board 3V lithium battery. A weak battery will result in "low battery" message.
When using the PG9905 temperature probe to monitor refrigerator temperature, install the temperature probe inside the refrigerator and install the detector on the wall or ceiling. For outdoor installations, install the temperature probe outdoors, and install the detector indoors. The detector comes equipped with a visible signal quality LED indicator that lets the installer choose the optimal location for installation, eliminating the effort of going back and forth to the keypad.
