Standing for Fire Alarm Bypass the Merlin FAB1 can be integrated with
any of the Merlin suite of products to give the operator the opportunity
to temporarily bypass the gas isolation system. With prior notice to a
fire alarm test, the operator can turn the key to the on position giving
an un-interrupted gas supply for between 10 and 45 minutes. During this
time the system controlling the gas will ignore shut-off signals from
the buildings fire alarm system and allow factors such as heating
systems to remain operational. The bypass time can be adjusted using the
blue switches inside the panel. During the bypass time gas can still be
shut off, pressing the emergency gas shut off button will close the gas
solenoid valve.
