Installation & Operation Manual
INSTALLATION
Planning
The Merlin 1500S acts as an interlock between the ventilation system and the gas solenoid
valve. It ensures the gas solenoid cannot be opened unless the ventilation system is proven to
be working and working at such a speed that is effective to exhaust the fumes from the
appliances.
The fans can be monitored through air pressure switches or by means of an additional current
monitor. To operate the Merlin 1500S the fans should be turned to the 'on' position, once the
panel receives a signal to indicate the fans are operating the key on the panel can be turned
to the 'on' position and this will open the gas solenoid valve. If the fans should fail, the 'fan fail'
LED on the panel will illuminate and the gas solenoid will close.
The Merlin 1500S can work in conjunction with carbon dioxide, natural gas, carbon monoxide
and LPG sensors.
Please refer to your detector manual for important information regarding coverage,
location and positioning including areas and conditions to avoid.
Fixing - Mounting
Unpack all the parts!
1. Carefully remove the front cover from the unit by unscrewing the four bolts located at each
corner. To do this – use the socket wrench provided.
2. Mark the four screw holes located on the back of the enclosure to the wall. Ensure the wall
surface is flat to prevent base distortion.
3. After executing the mounting and the connections – replace the front cover and insert the
security caps over the four bolts.
Be careful when creating access for cables – Damage to boards will void any warranty.
Carefully remove the circuit board before drilling cable entry holes.
