INSTALLATION 

   Planning 

 

This panel is designed for use when the kitchen appliances do not have flame failure devices 
fitted, therefore gas proving is a requirement. 
The Merlin 2000S system acts as an interlock between the ventilation system and the gas 
solenoid valve. The system is compatible with both current monitors and air pressure 
differential switches in order to interlock with up to 4 fans. 

 
The fans can be monitored through air pressure switches or by means of an additional current 

monitor. To operate the Merlin 20

00S 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 2000S can work in conjunction with carbon dioxide, natural gas, carbon monoxide 
and LPG sensors.  
 

 

 

   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. 

 

 

 

 

Please refer to your detector manual for important information regarding coverage, 

location and positioning including areas and conditions to avoid. 

 

 

Be careful when creating access for cables 

 Damage to boards will void any warranty. 

Carefully remove the circuit board before drilling cable entry holes.
