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.
