Gas Sensor for Pima Intruder Alarm

Wireless Gas Detector for Vision and Force Series Systems

DGS187 is a wireless gas detector. It is designed to detect Liquefied Petroleum Gas (LPG) mainly used as fuel in heating appliances and cooking equipment, and wirelessly transmit an alert to the control panel.

The detector monitors the presence of the above gases once every 160 seconds. Once the concentration of the gases reaches the detection threshold, it will trigger an alarm, by sounding beeps every one second, along with flashing with the red LED.

Powered by 220VAC transformer, the detector is connected using a micro USB cable (included).
