PWR20 – additional power supply with bus
repeater and three PGMs
Disconnect the system from 230V AC
power supply, pull out the battery cable
plug from the BAT socket. Make a short
circuit between the PGM output and
zone Z1 (see diagram) using a wire.
Power up the system with battery is
unpluged. As these actions has been
done it is possible to enter the service
mode using restored default service
PIN = “0000".

Intruder alarm system
Modules PWR15, PWR20 are powered
by a separate power transformer, a
separate rechargeable 12V 7Ah battery
should be wired. If alarm system includes
PWR15, PWR20 it is recommended to wire
an outdoor siren to the PWR15, PWR20
terminals +BELL, -PGM1 (-PGM2) and
COM by the way as it is shown on page 2.
Thus at trouble of the battery of an outdoor
siren or short circuit in the power wires of an
outdoor siren the increased current will
have no influence on the control panel
operation.
The repetition of bus is a perfect solution when the criminals
are trying to neutralize the security system by shorting the
keypad wiring located near an entry door or the PROX8
wiring with a hope it will disturb the operation of the system.
In this case only the modules wired to the bus repeated by
PWR20 would stop operate, but the remaining part of the
system would operate, would send a burglary alarm report
and would cause additional difficulties to the intruders.
The terminals CLK, DAT and COM of the control panel
PAS8xx are wired to the terminals CLK-I, DAT-I and COM
of the module PWR20. Re-transmitted bus appears on the
CLK-O and DAT-O terminals. Modules that use the re-
transmitted BUS are powered by PWR20 output +AUX.
For the attachment of keypads use only
self-tapping screws with flat (countersunk)
head (3x30 PH). Make sure that the screw
is screwed completely and the head is
sinked into the wall of the housing. If you
are using other type of screws or if you fail
to screw them fully there is a possibility of
the screw touching the keypad electronics
wich would cause the keypad fail.
Connect 12VAh/20HR battery to the PAS8xx BAT connector. With an
additional wire connect the negative battery pole to the PAS8xx COM
terminal for a short time. The system will start operate however the AC
loss trouble will be indicated.
