Merlin GDP2

General information

The Merlin GDP2 is a two-zone gas detection panel which can be used in many applications, e.g.

factories, car parks, shopping centres and the most common being a boiler house application.

Many varieties of detectors are compatible with GDP2, e.g. Natural Gas, Carbon Monoxide, LPG,

Refrigerant Gas and Oxygen depletion. These detectors can be used in any combination. Also multiple

thermal links can be used, when wired in series. The GDP2 can be integrated with a BMS, fire alarm

and remote emergency shut-off buttons.

It is recommended that the user reads this guide before using the system. Please do NOT attempt to

operate the unit until the contents of this document have been read and are thoroughly understood.

Installation

2.1

Panel Mounting The control panel is designed for surface mounting using 4 mounting screws.

Removing the cover on the panel gives access to the circuit board.

2.2

Mains Supply A 100-240VAC electrical supply should be supplied to the panel. This should be

externally fused at 3 Amps using a fused spur and should be connected to the terminals marked "LNE

Power"

2.3

Gas solenoid valve The gas solenoid valve should be powered using the terminals on the

Merlin GDP2 marked "LNE GAS VALVE".

Gas Detector The terminals detailed on the circuit board as "Gas Detector Zone 1" & "Gas

2.4

Detector Zone 2". These connections are "+,-" and "CL" and can be wired to a Merlin gas detector.

Natural gas, Carbon monoxide or LPG. Other detector types are available.

2.5

Remote emergency shut off buttons The terminal for remote emergency shut-off buttons is

detailed on the circuit board as "EM REMOTE". These connections are linked out as a factory setting.

Remote emergency shut-off buttons should be volt free and wired to the Merlin GDP2 using two-core

cable.

Heat Detector The terminal for heat detectors is detailed on the circuit board as "HEAT

2.6

SENSOR". These connections are linked out as a factory setting. Heat detectors should be volt free and

wired to the Merlin GDP2 using two-core cable.

Fire Alarm The terminal for fire alarms is detailed on the circuit board as "FIRE PANEL".

2.7

These connections are linked out as a factory setting. Fire alarms should be volt free and wired to the

Merlin GDP2 using two-core cable.

2.8

BMS Connections Terminal connections are available on the circuit board for connections to

Building Management systems etc. Detailed on the circuit board as "BMS OUT N/O, COM and N/C"

these are volt free connections.

2.9

Sounder Alarm The terminal for sounder alarms is detailed on the circuit board as

"SOUNDER/STROBE". Sounder alarms should be wired using low voltage cable and wired to the Merlin

GDP2 using two-core cable. This terminal has a 24VDC output.

2.10

Internal Buzzer Operates at 90dB measured 30cm from closed panel.

Mute The button on the front fascia of the panel detailed "MUTE", mutes the internal buzzer.

2.11

Note: all low voltage connections should be made using a screened cable. To avoid electrical interference

this should not be in the same conduit as mains cable as per the low voltage directive.
