Fire Alarm Integration
The Merlin 1000S+ can be integrated with a fire alarm to close the gas supply automatically in
the event of a fire.
The volt free fire alarm signal can be wired in series with any remote emergency shut off
buttons. If there are no remote emergency stop buttons being installed, wire this directly to the
1000S+ terminal marked [EM REMOTE].
3.6
Fan switch integration
There is the facility to connect a Fan Switch (FS1 or FS2 sold separately).
The Fan Switch provides the facility to turn on the fan(s) when the key switch on the Merlin
1000S+ is 'ON' and turns the power off to the fan(s) when the key switch on the Merlin 1000S+ is
in the OFF position. There is a dip-switch located inside the facia of the Merlin
1000S+ labelled [EM SEL].
This is factory set to 'OFF' which instructs the 1000S+ to shut down the fan(s)
and gas supply on activation of the emergency shut off button(s).
Upon installation, this can be switched to 'ON' - this will instruct the system to
leave the fans on and only shut off the gas supply on activation of the
Emergency shut off button(s).
Note: This option is not available if Fan Switch is not installed.
3.7
Auto reset
The Merlin 1000S+ has an auto reset feature.
There is a dip-switch located on the inside facia of the Merlin 1000S+
labelled [AUTO RESET]. This is factory set to 'OFF'. When the power is restored
after the power cut, the panel has to be restarted manually.
Upon installation, this can be switched to 'ON' if required - this will instruct
the system to restart automatically when power is restored after the power
cut.
3.8
Gas fill and prove time
Gas fill and prove times are adjustable.
There are two dip-switches located on the inside facia of the Merlin 1000S+ labelled [FILL TIME]
and [PROVE TIME]. They are factory set to 'OFF'.
FILL TIME is the amount of time the gas valve is open to fill the gas line.
Off – 5 seconds
On – 10 seconds
PROVE TIME is the amount of time the system tests the gas line for any leaks.
Off – 30 seconds
On – 50 seconds
Once the settings have been changed please remove mains power for 10 seconds.
