X Chain ID Switches
When wiring multiple detectors to the
GDP-X range it is important to identify
each detector and in which monitoring
zone the detector is located - for the
GDP-X system to receive and display
accurate data.
The diagram opposite shows how to
configure switches for each detector and
is also printed onto the detector circuit
board for quick reference.
For more information - refer to your GDP-X manual.
Audible Alarm Switch
There is a switch on the detector-TFT board [Buzzer On/Off].
The user can choose whether to have an audible alarm
when dangerous gas levels are detected.
The alarm will continuously sound – there are no provisions to
silence the alarm, gas levels must drop to a safe level for the
alarm to stop.
The buzzer measures approx. 65dB from a distance of 300mm/1ft (tested in quiet conditions).
