SATEL ACU-220

According to the EN50131-3 standard all ABAX 2 system Hold-Up devices must be
always in active mode.
The battery life time in the detectors switched permanently into the active mode is
shorter than in those which are periodically switched to the passive mode. However, if
the specific character of a detector or its installation place is such that the number of
alarms is low, switching the detector permanently into the active mode will not have
a significant effect on the battery life.
8.1.4.2 Wireless sirens
Turning on the output to which the wireless siren is assigned will trigger the signaling.
Depending on the siren:
ASP-200
– the first output controls the acoustic signaling, the second – the optical signaling.
Thanks to a high-capacity battery, the siren can receive transmissions from the controller
at any time. Therefore, the commands to start/stop signaling are sent to the siren
immediately.
ASP-215
– both outputs can control the acoustic and optical signaling. This enables two
different, independently triggered types of signaling to be configured. The outputs can
control separately the acoustic and optical signaling or trigger other signaling for different
alarms (e.g. burglary and fire).
Given its low-capacity battery, the siren can receive
transmissions from the controller during periodical communication only. Therefore, the
commands to start/stop signaling are sent to the siren during periodical communication.
Consequently, the operating time of outputs controlling the siren should be longer than the
communication period.
The signaling will stop after the maximum signaling time expires, even if the output is still
active.
The zones to which the wireless siren is assigned are activated if the signaling is triggered
(select the appropriate zone type). If the siren tamper is to trigger tamper alarm, program the
zone as 2EOL/NC or 2EOL/NO.
The tamper information is sent immediately, and the signaling state information – during
periodical communication.
8.1.4.3 Wireless expanders of hardwired zones and outputs
You can configure the alarm system zone/output to which expander zone/output is assigned
in much the same way as hardwired zones/outputs. You must, however, keep in mind that
sensitivity of the expander zones may be different from that programmed in the control panel:
from 20 ms to 140 ms – corresponds to sensitivity programmed in the control panel;
above 140 ms – only some values are available: 400 ms, 500 ms, 700 ms, etc. every
200 ms (the programmed value is rounded up to that supported by the expander).
The EN50131-3 standard requires that zones must react to signals lasting more than
400 ms. Therefore, select 400 ms when programming sensitivity of the alarm zones.
Information on the state of zones and commands to change the state of outputs are sent
immediately. Zone settings are sent during periodical communication.
If communication with the controller is lost, all previously activated outputs will be
deactivated after 20 communication periods.
If the ACX-220 expander is powered from a power supply unit connected to the APS
connector, the low battery information provided by the control panel means:
first zone – power supply overload,
second zone – low battery,
