Installation & Operation Manual

INSTALLATION

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.

Placing the panel at eye level allows for optimum monitoring of LED Indicators.

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.

A flush mount kit is available, comprising of a mounting bracket and decorative surround strip.
