12V DC EXTERNAL
POWER SOURCE
The WRLYB-1 can be powered by a 12V external
power source (not supplied) in order to operate as a
functioning relay unit, connecting FireAngel wireless
alarms to suitable other systems such as Fire Panels,
Telecare Systems, Auto Diallers, Security Systems etc
• Ensure to locate next to the DC external source.
• Locate the auxiliary power output in the DC external
source and wire it to the DC Power Input connector
on the unit.
• Check that the polarity of the auxiliary power supply
has been wired correctly and the power LED is on.
If the relay unit is powered from a DC external source,
the LED will flash GREEN once every 60 seconds.
In the event of an alarm when the relay unit is powered
from a DC external source, the red LED on the relay will
activate continuously and the buzzer will sound a pulse.
Please note: The maximum length of the lead for
the 12V DC supply should be no greater than 25m.
IMPORTANT: Please note that in the event of a
mains failure, the relay is not equipped with a
dedicated battery back-up function and therefore it
will not switch the contacts if there is an alarm on
the local network.
12–24V EXTERNAL TRIGGER
INPUT
The WRLYB-1 is capable of receiving an external
trigger input from elsewhere in a property such as
an external control panel. The external trigger input
voltage is optional and can be triggered by a 12-24V
DC power supply.
CONTACTS AND OPERATION
The WRLYB-1 is equipped with 2 x NO/NC contacts
rated at 250V AC-5A / 30V DC - 5A.
Each contact has both pulse and continuous modes of
operation, determined via dipswitch selection at the
point of install (3 & 4).
