Merlin GDP4 4-Zone Gas Detection System

Merlin GDP4 4-Zone Gas Detection System

The Merlin GDP4 is a multi-safe zone gas detection panel which can be used in many applications such as factories, car parks, shopping centres and most commonly - boiler houses. It can be used with up to 12 Merlin gas detectors (3 detectors per zone terminal) for monitoring and detecting gas including carbon monoxide, liquid petroleum gas and methane.

The controller panel can be integrated with, but not limited to, a BMS (building management system), a fire panel, external alarms and remote emergency shut-off buttons. Locations for detectors will vary based on the intended application and target gas, they should be located near identified sources of a potential gas leaks/ pockets where hazardous gas could quickly accumulate and areas of identified consequential risk.

The composition of the target gas and its density relative to air are used as the basis for any recommended height of detector placement. Generally, the installation height of a detector for a heavy gas (such as propane) would be close to the lowest point in the area, and for a light gas (such as methane) would be close to the highest point in the area.

Any recommended heights may vary based on air flow and temperature conditions in addition to the proposed application and location – this is particularly apparent with oxygen depletion sensors, and the target gas that they are used for

A Gas Safe installer would be required to fit the gas solenoid valve. Check the register at www.gassaferegister.co.uk.
