The Merlin GDPX+ is a 16 zone gas pressure proving & detection
panel which can be used in many applications, e.g. mechanical rooms, car
parks, shopping centers and the most common being a boiler house
application.
Utilizing a solenoid valve and a pressure transducer the Merlin GDPX+
will check for a pressure drop or leak in the downstream line before
allowing the gas to be supplied. Once gas has been supplied the unit
will constantly check the incoming gas supply pressure to ensure that a
naked flame cannot be extinguished by a weak draft.
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. When changes have
been, the system will automatically restart once the settings switch is
off.
Many varieties of detectors are compatible with GDPX+, e.g. Natural
Gas, Carbon Monoxide, LPG, Refrigerant Gas and Oxygen depletion. Up to
16 detectors can be used in any combination and can be individually
monitored on the GDPX+ TFT display.
Also multiple heat detector links can be used, when wired in series.
The GDPX+ can be integrated with a BMS, fire alarm and remote emergency
stop buttons. Gas detectors are fixed remote from the GDPX+ panel &
should be wired back to the GDPX+ panel with four wire low voltage
cable.
