6.3 Alarm states
The reader module can get in following alarm states:
1) Tamper alarm
2) Forced door alarm
3) Door ajar alarm
4) Antipassback alarm (Time APB alarm, Zone APB alarm)
5) ID with Alarm flag alarm
Alarm state reporting is performed as follows:
•
Via communication line (statuses 1, 2, 3, 4, 5)
•
By acoustic signal (beeper) (statuses 1, 2, 3, 4).
•
Activating the alarm output (AUX output) (statuses 1, 2, 3, 5).
Alarm signaling via communication line requires online running PC with relevant software
suitable for online operation (APS 400 nAdministrator).
Two ways of acoustic signaling is carried out:
•
Steady signal (tamper).
•
Intermittent signal (forced door and/or door ajar, APB alarm).
Acoustic alarm signaling is stopped after a valid ID is presented or pre-set time interval is
elapsed, see the configuration table.
If any of the relevant alarm states
(with setting of the signaling timer > 0)
occurs, the alarm
output is activated. It can control any alarm device directly or it can be processed further.
After terminating all alarm conditions the alarm output is deactivated.
The alarm signaling is triggered by any alarm condition.
6.3.1 Tamper alarm
In case of tampering the module (by tearing-off or opening the cover or changing the status
of input 2 or input 3
in proper configuration) the “Tamper” state is activated
3)
.
3)
The Tamper alarm handling is operational after their first change of status since switching
on the module. There is no need to configure the module when the tamper protection is
not used.
6.3.2 Forced Door alarm
The “Forced Door” alarm state is activated when the door is opened without activating the
“Door Open” function. The only exception is opening the door with the second module input
IN2 active and configured as a handle contact.
6.3.3 Door Ajar alarm
If the door stays open until the pre-defined Door ajar timeout expires
– see
Tab. 12
, the “Door
Ajar“ alarm is activated.
