armed or disarmed: they are always armed. As for the “Bypass” zone, the zones of this type are handled during
arming or disarming in a special way, as described above, in the section “Zone Types”.
“Probable Alarm” Event
If the zone with entry delay is violated, the device certainly generates the “Probable alarm” event (** E138 **). The
number of the violated zone and the smallest number of the part, into which this zone is included, are transmitted
as the event arguments. If several zones with entry delay are violated, an event “Probable alarm” will be generated
for each zone.
On some sites, the control panel cannot be placed so that it is located in a separately guarded part of the room.
Typically, these sites can include small rooms: shopping pavilions, garages, small offices and apartments. This
means that during the entry delay countdown, the control panel can be disabled. The “Probable alarm” event
allows the security panel to monitor the device operability after the entry delay countdown begins: if there is no
event after the start of the entry delay, when the device is disarmed, it is an occasion to find out what is happening
at the site.
To automatically monitor the reception of a disarming after a possible alarm in the Security Center, it is necessary
to use the “Alarm entering” event handler or the “Event chain monitor” event handler.
5.3.8
Exit Delay
The purpose of the “Exit delay” parameter is very similar to that of the “Entry delay” parameter, but it is intended
to allow the user to exit the guarded premises after he/she performed the arming. As a rule, the exit delay is set
for zones that protect the entrance doors to the protected premises.
After the user arms the part (using the keyboard, wireless controller or TM reader), the device checks the status of
all zones included in the part:
∙
if a faulty cable is detected, the device refuses to arm;
∙
if the alarm zone is detected, the device also refuses to arm;
∙
if there are no faulty or alarm zones, the device is armed and the exit delay counts, if any.
The arming event (
E401
) is generated immediately during arming, before the exit delay starts, if any. The number
of the protected part and the number of the user, who performed the arming, are transmitted as arguments of the
event.
After the exit delay countdown starts, the device ignores the status of all zones for which an exit delay is specified,
as well as zones with a “Bypass” type. If the user has time to leave the premises and close the entrance door before
the exit delay countdown has expired, then there will be no alarm after arming. If any of the zones are violated
after the exit delay ends, an alarm will be generated.
For wireless devices, the state that was received during the last poll of the device is taken as current. Thus, the
user of the wireless system may need to wait until the wireless detector sends a normal state to the device. In case
you do not want to wait, it is possible to set the minimum possible delay for the wireless detectors.
It may happen that during the arming it is impossible to achieve the normal state of one or several zones, for
example, if the detectors in the zones monitor the keyboard area. In this case, the zones shall be configured as
bypass
. The bypass zones are described in more detail above, in the section “Zone Types”.
An alarm in the zones with exit delay at the time of arming is ignored. This is done so that the user does not
have to check and close the front door. But, if you want to be sure that all alarm zones are normal at the time of
arming, it is possible to turn on alarm monitoring in zones with exit delay at the time of arming. To do this, check
the parameter “Disable arming when triggering the alarm in zones with exit delay” in the “Miscellaneous” tab, in
the “Arm and disarm” section.
