Receiver Operation:
Output activation: The FA404 has N/O open collector Alarm and Fault outputs. Output is open relative to ground.
On activation, output pulls to common ground. The FA404R has Form C Alarm and Fault relay outputs. Output
activation is indicated by illumination of the
ACTIVATED LED
. Note: if a receiver is being connected to a normally
closed zone, the FA404R must be used.
Connection to hardwire panels: When an FA404 or FA404R receiver is used with a hardwire security panel, the
panel will typically supply power and ground to the receiver. When the ground supplied to the receiver is common
to the return loops of the hardwire panel, use one wire to connect each of the FA404 receiver outputs to the zone
input of the panel. Supervision resistors in N/O loops must be placed in parallel. Supervision resistance in N/C
loops must be in series. The examples below show typical connections of both the FA404 and the FA404R.

WARNING: To clear a latched fault or alarm, press
RESET
. Make sure that the receiver is not in program mode
or the transmitter will be deleted. Test all transmitters prior to leaving the site.
If the panel has N/O zones and can recognize 3 zone conditions (open=fault, short=alarm and EOL
resistance=normal), both the alarm and the fault outputs can be attached to the same zone as shown below.
