Instruction manual PSV 1225-18
DESCRIPTION
PSV 1225-18 is an up-to date power supply unit with bat-
tery backup compliant with EN regulations for social and
security alarm systems. Unit provides all features required
by EN 50131-6:2008, security grade 2 and many other
available in grade 3 only.
Distinctive and unique feature of PSV 1225-18 is invented
by Alarmtech ViP mode –Voltage-in-Parallel. Power sup-
ply units with ViP feature can be connected in parallel both
(+) and (-) on one common power bus without a need of
additional synchronization. Connected units will share
load on a bus. ViP feature can be used to build distributed
and redundant power systems. It can be also used to com-
pensate voltage drops on a bus by placing power supply
units in distant bus sections.
Power conversion is based on high frequency SMPS regu-
lator providing high conversion efficiency. Low losses in-
side unit preserve batteries from overheating shortening
battery life time. Computerized battery recharging circuit
works in constant current –limited voltage mode –the
most advanced and the best mode to provide the longest
possible battery life time.
Power unit is equipped with built-in diagnostic system de-
tecting and signalling mains failure, different battery fail-
ures including end-of-life warning, output faults like low
voltage or broken fuse.

1. INSTALLATION
PSV 1225-18 power supply installation and start-up pro-
cedure:
•Fix unit in destination place using 4 fixing holes
•Place sealed lead acid battery 12 V/18 Ah in battery
chamber
•Make connection between left battery (-) and battery
connector using black battery cable
•Make connection between right battery (+) and bat-
tery connector using red battery cable
•Make appropriate connections between power output
and power receivers
•Make required connections between signalling outputs
of PSV 1225-18 unit and cooperating units (outputs
EPS, APS, OUT, SAB, input –RBT*)
•The socket outlet delivering 230 VAC shall be installed
near the power supply unit and shall be easily accessi-
ble
•Make sure that cable delivering 230 VAC to power sup-
ply is disconnected from mains
•Connect 230 VAC cable to 230 VAC input in power sup-
ply unit –make sure that PE cable is connected to PE
input
•Switch on mains delivering energy to power supply -
PSV 1225-18 unit will start automatically delivering
power to the load and monitoring state of PS

2. TECHNICAL DESCRIPTION
2.1 Front panel
Power supply unit is equipped with front panel showing actual general state of unit. Three LED’s display shows:
Green LED: mains voltage present –unit in EPS mode supplied from mains
Yellow LED: mains voltage missing –unit in APS mode supplied from battery
Red LED: fault detected –quick visual identification and localisation of failure is possible with help of set of
diagnostic LED’s in power unit
2.2 Internal state monitoring functions in power unit
All monitored states of PS are displayed with help of LED diodes for quick visual identification. The placement of moni-
toring LED is documented in below placed drawings. The meaning of LED colours is following:
