General Information

The Merlin FAB-1 is a fire alarm bypass panel.
The Merlin FAB-1 is designed to allow gas to remain on- for a pre-determined time during a fire
alarm test. The FAB-1 should be activated before a fire alarm test to allow the gas supply to
remain on. This is done by turning the key switch on the fascia of the panel as far clockwise as
possible. Once released the key will return to its original position and a countdown timer is
activated. The countdown timer can be adjusted inside the panel to allow the gas supply to
remain on for between 10 and 45 minutes.
When the FAB-1 is in operation the panel will beep every 20 seconds until there is 5 minutes
before the end of the timeout, the FAB-1 will then beep every 10 seconds and the bypass LED
will start to flash. During the bypass time gas can still be shut off, pressing the emergency shut
off button will close the gas solenoid valve.
It is recommended that the user reads this guide before using the system. Please do NOT
attempt to operate the unit until the contents of this document have been read and are
thoroughly understood.
