GS100M Fascia & PCB Layout
No Description Purpose & Functionality
1 ON
LED illuminates when supply voltage is applied.
LED flashes during self diagnosis start up.
2 BATTERY This LED illuminates when the GS100M is being poered by standby battery
3 BATTERY OVERLOAD LED Illuminated to indicate incorrect battery connection or high consumption during charging phase.
4 SENSORS OVERLOAD LED Illuminated to indicate short circuit or overload on sensor circuitry.
5 ALARM Indicates alarm status (explosive or toxix levels have been reached)
6 TOXIC / EXPLOSIVE
Toxic (Skull) LED illuminates when DIP switch for sensor is in CO (Toxic) position
Explosive LED illuminates when DIP switch for sensor is in GAS (Explosive) position
7 PRE ALARM LEDS
Indicate level of gas sensed (8 - 13 - 20% LEL / 120 - 200 - 300ppm)
8 RESET When pressed resets the detector after an alarm or sensor fault condition.
9 TEST
When pressed checks the sequence and function of GS100M.
Press and hold to initiate a full function test, release once controller is in alarm state required
Will eventually activate all relays and their associated outputs .

PRE ALARM
Illuminates at 8% LEL (Explosive) or 120ppm (Toxic) gas concentration:
LED illuminates and the Pre Alarm relay 1 is actuated.
11 2
nd
PRE ALARM
Illuminates at 13% LEL (Explosive) or 200ppm (Toxic) gas concentration:
LED illuminates and the Pre Alarm relay 2 is actuated.
12 MAIN ALARM
Illuminates at 20% LEL (Explosive) or 300ppm (Toxic) gas concentration:
LED illuminates and the Main Alarm relay is actuated.
13 FAULT Indicates short circuit, sensor fault, loss of signal or incorrect sensor connection.
14 Supply & Relay Terminals Electrical supply and relay connections. (See Wiring Schematic for connection instructions).
15 Sensor switch
Used to enable or disable the sensor zone (ON/OFF) or determine type of gas to be detected (Toxic/Explosive)
- (See Configuring the GS100M section for setting instructions).
16 Positive Safety switch Positive Safety switch (See Configuring the GS100M section for setting instructions).
17 Main Alarm Relay actuation
Determines if Main Alarm relay remains in position even if gas levels drop below alarm threshold.
(See Configuring the GS100M section for setting instructions).
18 Sensor/ Battery Terminals
Sensor and Battery (if fitted) terminals (See Wiring Schematic for connection instructions).
