5 3 Connections
Connect the gas detector as shown in '8 Wiring diagram' .
5 3 1 Power supply
The gas detector is suitable for both 12 and 24 Volt.
The fuse in the plus wire of the gas detector only protects the gas detector itself and does not
protect any gas valve, alarm or fan connected!
5 3 2 Gas valve
An electrically operated gas valve can be connected to the output 'VALVE' . The gas valve is
incorporated in the gas supply line. If there is an alarm situation the valve will be closed auto-
matically and shut off the gas supply to the installation.
The gas valve must operate at the same voltage as the power supply to the installation, either
12 or 24 volt direct current respectively. The output 'VALVE' is suitable for a gas valve requiring
a current of maximum 1 A. Fit a 1 A fuse in the plus wire to the gas valve. NB: the gas detector
switches the minus connection (-, earth) to the gas valve!
5 3 3 External Alarm
An external alarm (for example, a hooter or buzzer) or a contact for an alarm system can be
connected to the output 'ALARM' .
If there is an alarm situation the external alarm will be switched on automatically.
The external alarm (hooter or buzzer) must operate at the same voltage as the power supply
to the installation, either 12 or 24 volt direct current respectively.
The output 'ALARM' is suitable for a hooter or buzzer requiring a current of maximum 1 A. Fit
a 1 A fuse in the plus wire to the hooter or buzzer. NB: the gas detector switches the minus
connection (-, earth) to the hooter or buzzer!
5 3 4 Ventilator
An electric fan can be connected to the output 'FAN' . The fan is to replenish the air in the room
being monitored.
If there is an alarm situation the fan will be switched on automatically.
The fan must operate at the same voltage as the power supply to the installation, either 12 or
24 volt direct current respectively.
The output 'FAN' is suitable for a fan requiring a current of maximum 1 A. Fit a 1 A fuse in the
plus wire to the fan. NB: the gas detector switches the minus connection (-, earth) to the fan!
Gasdetector GD1000
The fan must be ignition protected!
