- the slow flashing of a zone LED and of the ALARM LED (whether

enabled or not) if the fault involves the detection zone with which the

LED is associated.

• The second provides cyclical control (about every 24 hours) of the

efficiency of both the microwave and the infrared zones. If this type of

control gives negative results (e.g., due to a fault in one of the two

detection zones), this condition is still indicated by the slow flashing of

the zone LED (the one involving the fault) and of the general (ALARM)

LED, in addition to the relevant indication at the FAILURE output (see

Par. 9.15).

9.15 FAULT OUTPUT (FA Terminal - Fault )

The OPEN COLLECTOR output goes to GND in case of a sensor fault

(Imax = 10 mA).

The fault output is activated in case of an internal fault or as a result of

operating voltage values that are out of range (see Par. 9.14).

In such cases, the output remains activated and the LED('s) flash slowly

until the cause of fault is eliminated.

N.B.: In the presence of a fault in one detection zone, the sensor

automatically changes its operating mode: if it has an AND

configuration, in the presence of a fault in one of the two detection zones,

the sensor automatically switches to OR operation and cuts out the faulty

zone;if it is configured for OR operation, in the presence of a fault in one

of the zones, the latter zone is not taken into account. This condition exists

for as long as the fault persists (however,it is indicated, as stated above).

9.16 ENVIRONMENTAL TEST

The environmental test is useful in providing an indication of the amount

of noise the sensor detects in the environment.

To apply this test the MW and PIR zone leds must be enabled and the

sensor must be operating inside an armed system (see Par. 9.2 relative to

"TC". The JP2 jumper must also have the following configuration.

JP2 NOT CONNECTED: Environmental Test disabled

JP2 CONNECTED:

Environmental Test enabled

PROCEDURE

1. After enabling the test by connecting jumper, close the sensor cover.

2. The sensor now begins the Environmental Test and adapts its sensitivity

for this purpose.

3. Wait a few seconds without making any movements and check whether

the two zone leds (MW and PIR) light up: if leds remain OFF, it means

there is no appreciable environmental noise.

4. If the respective leds of both zones (MW and PIR) light up several

times (even individually), this means that the zone in question (or both

zones)has detected environmental noise; in this case, eliminate the

possible causes of the noise (e.g., draughts for the infrared, or excessive

closeness to fluorescent lamps for the microwave, etc.), and repeat the

test. If the PIR led continues to light up, it is advisable to operate the

SW1 DIP 4 and DIP 5 (see par. 7.0) to reduce detection sensitivity,

while, if the MW zone led continues to go ON, sensitivity should be

reduced (compatibly with the size of the area to be protected) by acting

on the MW RANGE adjustment trimmer (turning toward lower values)

and on the SW1 DIP 3 (maximum delay).

5. The Environmental Test condition lasts for as long as the JP2 jumper is

connected; disconnect the jumper after performing test to restore normal

operation.
