6.3 Connect the back-up power
The battery charger has six (main) screw terminals for connecting to the Voice Alarm System.
1. CLoad (main) to the plus terminal of the system components.
2. Connect -Load (main) to the minus terminal of the system components.
6.4 Connect the auxiliary power
The battery charger has pluggable Euro-style screw terminals for a 24 Vdc output (PLN-
24CH12) or 48 Vdc output (PRS-48CH12) to supply power for e.g.:
– Remote Control Panels (RCP)
– Volume overrides and general purposes
The auxiliary output terminals are protected against short circuits by means of a fuse (Faux1
to Faux3).
6.5 Connect the output contacts
The battery charger has three fail-safe outputs on the rear panel for remote monitoring. Each
output has three terminals: Normally Closed (NC), Common (C) and Normally Open (NO).
Connection is done via a 9-pins pluggable screw terminal connector. Refer to Table 6.2 for
contact status. See section 3.4.1 for LED status indicators.

NOTICE!
Do not use the main outputs to connect remote control panels or volume overrides. For this
purpose, use the auxiliary output terminals. Refer to section 6.4 .
NOTICE!
The auxiliary outputs are intended to power modules of the Voice Alarm System that do not
have their own mains power supply. The current drawn from these auxiliary outputs should be
subtracted from the 12 A the charger can use to charge the battery. E.g. if the total auxiliary
current is 3 A, the charger should be considered a 9 A charger when calculating back-up
requirements.
