8.8 PULSE COUNT (Infrared section)
By operating DIP x1-2, it is possible to select the number of pulses necessary
for the infrared section to generate an alarm condition.
DIP x1-2 on OFF: Count x 1
DIP x1-2 on ON: Count x 2
NOTE: If the Curtain or Long Range coverage is used, configureDIP x1-2 on
OFF.
8.9 FUNCTION: MICROWAVE SYNCHRONISATION
If it becomes necessary to considerably increase the level of protection in a
sector, with several sensors in one area for instance (i.e.: position very close
together), it is necessary to synchronise the emission of the electromagnetic
energy of the microwave modules to avoid problems of reciprocal interference
between the various modules which might generate false alarms.
With synchronisation it is possible to configure the sensor with maximum
sensitivity without having to use systems to reduce the detection capacity. This
is ideal for reducing the above-mentioned problems to the minimum.
For this purpose there is a "Sync" clamp (considered to be output of the MASTER
sensor and the input of the SLAVE sensors); the clamp is used as a support for
the synchronous line; it is important for this line to be "alone" and that it directly
links the sensors to be synchronised without having to pass through support
interfaces, etc.
A maximum of three sensors can be synchronised One of these is the MASTER
sensor, which is configured through the MST/SLV DIP of SW2.
Important! Of all the sensors to be synchronised, only one an be identified as the
MASTER sensor.
To distinguish the MASTER sensor (only one) from the SLAVE sensors (min. 1
and max. 2), it is necessary to configure the MST/SLV DIP of SW2 as follows:

MST/SLV DIP to OFF:
MST/SLV DIP to ON:
To distinguish the first SLAVE sensor from the second (If there is only one it is
absolutely secondary to define it as first or second), it is necessary to configure
the SLV1/2 DIP as follows:
SLV1/2 DIP to OFF: SLAVE 1 Sensor
SLV1/2 DIP to ON: SLAVE 2 Sensor
If the synchronism function is not used, leave the MST/SLV DIP and SLV1/2 of
SW2 in the OFF position.
8.10 MASKING SENSITIVITY
The antimasking system, which is separate for both detection sectors, constantly
protects the sensor from attempts at antimasking.
The specific antimasking system for the infrared zone consists of two activate
infrared transmitters and three receivers which detect solid bodies, substances
sprayed on the lens (on a HIGH SENSITIVITY sensor), paint, etc., when attempts
are made to discover/find the sensor.
The recognition of an attempt like this takes place at different times between the
two detection sectors and is displayed with the constant lighting up of the FAULT
led (yellow led) and with the opening of the contacts on the FA output, which is
unique to both detection zones and common for any fault messages.
Using the SENMSK DIP of SW2 it is possible to set a different level of sensitivity
for the antimasking function.
