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 fuel valve, alarm or fan connected!
5 3 2 Fuel shut off valve
An electrically operated shut off valve can be connected to the output 'VALVE' . The shut off
valve can be included in the fuel supply line to the engine, for example. In the event of an
alarm situation the shut off valve will be closed automatically so shutting off the fuel supply
to the installation.
The fuel shut off valve must operate at the same voltage as the power supply to the installa-
tion, either 12 or 24 volt direct current respectively. The output 'VALVE' is suitable for a fuel shut
off valve requiring a current of maximum 1 A. Fit a 1 A fuse in the plus wire to the fuel valve.
NB: the gas detector switches the minus connection (-, earth) to the fuel 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 PD1000
The fan must be ignition protected!
