The zones in the system to which the wireless sirens are assigned can be programmed as:
NC, NO or EOL – provides information about troubles (a trouble causes the zone
violation),
2EOL/NC or 2EOL/NO – provides information about troubles (a trouble causes the zone
violation) and about tamper.
The type of zones to which the wireless siren is assigned should be matched to the
information sent:
ASP-100
– first zone: low battery; second zone: tamper.
ASP-105
– first zone: low battery and tamper; second zone: external 12 V DC power loss
and tamper.
ASP-205
– both zones: low battery and tamper.
The tamper information is sent immediately, while the trouble information:
ASP-100
– during periodical transmission, which is sent every 15 minutes,
ASP-105
/
ASP-205
– during polling.
Tamper alarm on opening the tamper switch in the siren:
ASP-100
– lasts for the maximum duration of signaling programmed for the siren (sound type
selected during programming and optical signaling);
ASP-105
– lasts for the maximum duration of acoustic signaling programmed for the siren
(sound type selected during programming and optical signaling);
ASP-205
– lasts 3 minutes (sound type 1 and optical signaling).
Tamper signaling is blocked:
when the control panel is running in service mode,
when the ABAX system is running in test mode (ASP-105 and ASP-205),
for 10 minutes after connecting the battery (ASP-100),
for 40 seconds after power-on (ASP-105) / installing the battery (ASP-205).
It enables installation work to be carried out. Opening the tamper switch will not trigger
loud signaling, but information on tamper will be sent (when in service mode, the
control panel will not signal the tamper alarms). The command to block/unblock the
signaling connected with starting / ending the test mode or the service mode is sent
during the response time.
6.4.3 Wireless expanders of hardwired zones and outputs
The wireless expander of hardwired zones and outputs (ACX-200 or ACX-201) takes up 4
zones and 4 outputs in the system. The alarm system zone / output to which the zone /
output in ACX-200 or ACX-201 expander is assigned is programmed in the same way as the
other hardwired zones / outputs of the control panel. You should remember however that
sensitivity of the expander zones may be different from that programmed in the control panel:
– from 20 ms to 140 ms – the same as the value programmed in the control panel;
– above 140 ms – only some values are available: 300 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. It means in case of the wireless expanders of hardwired zones and outputs
that no values exceeding 300 ms should be entered when programming the sensitivity
(the higher the value, the lower the sensitivity).
The expansion module informs you about the zone status as it changes. Also the expander
outputs are controlled in real time. Only the programming of zones takes place during the
