6.3 Alarm states
The reader module can get in 3 alarm states:
•
Tamper alarm (against tearing-off the wall and opening a cover)
•
Forced door alarm
•
Door ajar alarm
Alarm state reporting is performed as follows:
•
Via communication line.
•
By acoustic signal (beeper).
•
Activating the alarm output (AUX).
Alarm signaling via communication line requires online running PC with relevant software
suitable for online operation (APS 400 nAdministrator).
Two ways of acoustic signaling can be carried out:
•
Steady signal (tamper).
•
Intermittent signal (forced door and/or door ajar).
Acoustic alarm signaling is stopped after a valid ID is presented or pre-set time interval is
elapsed, see the configuration table.
If any
used
alarm state
(with setting of the acoustic alarm timer > 0)
occurs, the alarm output
is activated. It can drive a low-input transistor relay which contact 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) the “Tamper” state is
activated

.
4)
The Tamper alarm contact and sensor are operational after their first change of status
since switching on the module. There is no need to configure the module when the
additional magnet is not installed.
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. 8
, the “Door
Ajar“ alarm is activated.
