  • Merlin GDPX+ Gas Proving and Detection System with remote monitoring

The Merlin GDPX+ is a 16 zone detection & gas pressure proving system which can be used in many applications, e.g. Boiler house / Plant room, highrise accommodation, car parks, shopping centers and battery rooms.

The GDPX+ has a touch screen which displays two modes, the engineers mode and the user mode. A settings dip switch inside the controller allows the engineer/user to configure the system to suit every requirement. 

Many varieties of detectors are compatible with GDPX+, e.g. Natural Gas, Carbon Monoxide, Carbon Dioxide,LPG, Hydrogen, Refrigerant Gas and Oxygen depletion.

Up to 16 detectors can be used in any combination and can be individually monitored on the GDPX+ (no need for additional expensive power packs)

Also multiple heat detector links can be used, when wired in series. The GDPX+ can be integrated with a BMS and fire alarms using Modbus, simple switch or LAN Network.
