The GSD-441 PG2 is a wireless PowerG two-way natural gas
(Methane) detector. The GSD-441 PG2 is a natural gas detector
designed to send an alarm when Methane gas is detected. The
detectors can be used in a house, apartment, caravan, mobile home
The detectors are powered by 220 VAC. An internal Lithium battery
is used for AC power failure reporting only (the battery does not
power the detector).
The detector can send the following messages to the alarm system
control panel: Gas alarm, gas sensor failure, AC power failure and
low battery voltage.
The GSD-441 PG2 is designed for wall mounting and should be
placed in a location where gas presence, for example leakage, is
Upon gas detection, an audible buzzer is sounded and the built-in
transmitter transmits a digital message, composed of the detector's
PowerG ID followed by status messages. Alarm and other data are
thus forwarded to the alarm system. A periodic supervision
message is transmitted automatically (see specifications) to inform
the alarm system at regular intervals, of the unit’s active
participation in the system.
