Merlin GDP4 User Guide General Information The Merlin GDP4 is a multi-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. The GDP4 can be used with up to 12 gas detectors wired in parallel (maximum 3 detectors per zone).
GAS VALVE The gas solenoid valve should be powered using the terminals on the Merlin GDP4 marked [GAS VALVE LNE]. GAS DETECTOR ZONE 1, 2, 3 & 4 These connections are [+,-] and [CL] and can be wired to a Merlin gas detector.
2.5 HEAT SENSOR The terminal for heat detectors is detailed as [HEAT SENSOR]. These connections are linked out as a factory setting. Heat detectors should be volt free and wired to the Merlin GDP4 using two- core cable. FIRE PANEL The terminal for fire alarms is detailed as [FIRE PANEL].
BMS Integration The Merlin GDP4 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.
