Operation Instructions

3.1

System ON and OFF

To turn the system on press reset to start the testing sequence.
The system will close the solenoid valve when an emergency stop has been pressed, gas has
been detected or any alarm signal has been triggered.
3.2

Mute Button

The mute button is located on the front fascia of the GDP2 and is used to mute the sounder
inside the board when in alarm.
The internal buzzer operates at approximately 90db measured 30cm from a closed panel.
The mute button is used to mute the sounder inside the board when in alarm.
3.3

Reset Button

The reset button is located on the front fascia of the GDP2 and is used to turn the system on
and to reset the system following alarm.
3.4

Emergency Shut Off

The emergency shut off button is located on the front of the panel.
There is also a facility for remote shut off buttons to be wired in series on the circuit board.
The emergency shut off button(s) will cut off the gas supply when activated.
To reinstate the system, the emergency shut off button(s) will need to be reset and the panel
restarted.
3.5

BMS Integration

The Merlin GDP2 can be integrated with a BMS to make or break a circuit
on gas on/gas off, (valve open or valve closed). This will tell the BMS
whether or not electrical power is being sent to the solenoid.
There is a dip-switch located on the inside facia of the Merlin GDP2
labelled [BMS]. This is factory set in the 'off' position which signals the BMS
on gas on/gas off.
When switched to the 'on' position, the GDP2 will only signal the BMS on a
fault, i.e. gas detected, EM Stop pressed, etc.

3.6 Auto Reset

The Merlin GDP2 has a built-in auto reset feature. There is a dip-switch
located on the PCB of the Merlin GDP2 labelled [Auto]. This is factory set in
the 'off' position. When the power is restored after the power cut, the panel
has to be restarted manually.
On installation, this can be switched to the 'on' position if required. This will
instruct the system to restart automatically when power is restored following
a power cut.
