enables the zone to be disarmed before an alarm is triggered. You can program up to
255 seconds. If value 0 is programmed, violation of the armed 4. DELAY zone type will
trigger an instant alarm.
Exit delay – parameter available in the alarm device mode, denoting the time counted
from the moment of arming. Violation of a 0. INSTANT or 4. DELAY zone type during the
exit delay countdown will trigger no alarm, which allows you to leave the protected area
without setting off alarm. You can program up to 255 seconds. If value 0 is
programmed, all zones will be instantly armed.
AC loss report delay – the time during which the module AC power must be lost for
a trouble to be reported. The trouble report delay prevents momentary outages, which
do not affect the normal operation of the module, from being reported. You can program
up to 99 minutes and 99 seconds.
SMS control
The following fields are available for the alarm device mode.
Arm – content of the control command which will be used to arm the module by means of
SMS messages.
Disarm – content of the control command which will be used to disarm the module by
means of SMS messages.
Clear alarm – content of the control command which will be used to clear alarms by
means of SMS messages.
Zones
Working parameters for hardwired and wireless zones are programmed in separate tables.
Wired zones
Name – individual name of zone (up to 16 characters).
Type – you can program the following wiring types (you can make your selection in the
right-click drop-down menu, or by entering a digit corresponding to the wiring type):
0. disabled – select this type, if no device is connected to the zone;
1. NC – select this type, if a device with normally closed contacts is connected to the
zone;
2. NO – select this type, if a device with normally open contacts is connected to the
zone;
3. – depending on the operating mode:
− communication device: 3. analog – select this type, if the zone is to supervised
analog signals;
− alarm device: 3. EOL 2k2 – select this type, if a 2.2 kΩ EOL resistor is used.
Sensitivity – time during which:
– the NC type zone must be disconnected from the ground so that the module can
register the zone violation,
– the NO type zone must be shorted to ground so that the module can register the
zone violation,
– the EOL type zone must be shorted to ground or disconnected from the ground so
that the module can register the zone violation,
– voltage on the analog zone must drop below threshold L (minus tolerance) or rise
above threshold H (plus tolerance) so that the module can register exceeding the
preset value (see Fig. 10).
Values from the 0 to 5100 ms range can be programmed (every 20 ms).
