JP5:
Cut to make
notification appliance
power on TB3
Terminals 3 and 4 a
resettable 2-amp
maximum circuit.
JP1:
When
employing a
CHG-120,
Remote Battery

must be cut.
Notification Appliance/
Annunciator Power
Power-limited, filtered, non-resettable, 3 amps
(in alarm) maximum. JP5 may be cut to convert
this notification appliance power (TB3 Terminals
3 and 4) to a resettable, 2-amp maximum circuit.
This output can also be used to power ACS
series annunciators (do not cut JP5).
JP2: must be cut
otherwise a short on the
notification appliance
power circuit (Terminals
3 and 4) would register
incorrectly as a loss of
primary (AC) power.
Earth Ground
Connect to chassis via a
Grounding Cable Assembly.
