Alarm cycles
This programmable parameter accepts values between 1 and 15. If you set the
value at 15, the zone will operate as a “repetitive zone” (refer to
Appendix A,
Technical terminology and Glossary
,
Alarm cycles)
.
Detector type
It is possible to configure a zone as:
•
Generic zone
•
Rollerblind
•
Shock
The following Table shows the terminals which accept Generic, Rollerblind and
Shock zones, and the respective zone-parameter fields for each type.
Al. pulse Duration
(generic zone)
This is the length of time (after detection of alarm conditions) the zone allows
before generating an alarm. Expressed in multiples of 15 milliseconds or minutes
(see “info” box).
Multipulse time
(generic zone)
This parameter applies only when the “Alarm pulse num." parameter is more than
1.
This is the window during which a number of alarm pulses must be detected
(each lasting as long as the programmed “Al.pulse Duration”). The number of
alarm pulses must equal or exceed the value programmed for “Alarm pulses”,
before the system generates an alarm. This window can be expressed in seconds
or minutes (see Note).
Alarm pulse num.
(generic zone)
This is the number of pulses (each lasting as long as the programmed “Al.pulse
Duration”) necessary to generate a zone alarm event. If this value is more than
1, you must also programme the “Multipulse time” parameter.
Rollerblind time
(rollerblind zone)
This parameter applies only when the value of the “Rollerbl. pulses” (see below)
is more than 1.
This is the time window during which the system must detect a number of pulses
equal to or higher than the value programmed for “Rollerbl. pulses” before
generating a zone alarm. This window can be expressed in seconds or minutes
(see Note).
Rollerbl. pulses
(rollerblind zone)
This is the number of pulses necessary to generate a zone-alarm event. If this
value is more than 1, you must also programme the “Rollerblind time” parameter.
Shock sensit.
(shock zone)
This is an empirical parameter which regulates the sensitivity of the sensor.
Increasing this value decreases detection sensitivity.
Shock time
(shock zone)
This parameter applies only when the “Shock pulses” value is more than 1.
This is the window during which a number of pulses must be detected the number
of alarm pulses must equal or exceed the value programmed for “Shock pulses”,
before the system generates an alarm. This window can be expressed in seconds
or minutes (see Note).
Shock pulses
(shock zone)
This is the number of pulses necessary to generate a zone-alarm event.
If this value is more than 1, you must also programme the “Shock time”
parameter.
If this value is 0, the zone alarm will be generated by the “Shock sensit.”

Al. pulse Duration
Multipulse time
Alarm pulses
Rollerblind time
Rollerbl. pulses
Shock sensit.
Shock time
Shock pulses
If this value is
expressed in minutes,
there is an error margin
of 1 minute (for
example, if you set 5 minutes,
the period can vary between 4
and 5 minutes).
