DT12-DT122 - Handbook for the customer
IMPULSE-COUNTER
Every flash by the RED LED (it means every Microwave + PIR detection, only Microwave or only PIR) is
counted. When the level set on the impulse-counter is exceeded the RED LED turns on and the relay
excites generating the alarm.
ONLY DT122: If the infrared sensor turned downwards detects a great movement, any is the
number of impulses set and the activation/deactivation status of the OR function (anti-
masking), the detector goes into alarm, turns on the red LED with fixed light and opens the
contacts on the OUT output immediately without waiting to achieve the number of impulses set or
detecting the movement with the microwave radar overtaking the "automatic AND/OR function",
the "AND function" and the "impulse counter".
SWITCH1/SWITCH2 Position the dip-switches according to the value desired.

SIGNALLING LED EXCLUSION
Turning the dip switch 4 on ON (SW=ON) the detection and alarm signals of the LEDs are disabled. The
only signalling still active are the initial flashing in the detector turn-on phase and the flashing for the
memory input activation.

SW4=ON (activated exclusion)
LED FUNCTIONING SUMMARY
Red LED: by applying power supply voltage it turns on for approx 30 seconds during the circuit
stabilization stage.
Yellow LED:it turns on to signal the infrared detection activity (1 element Digipyro™ DT12; 2
elements Digipyro™ DT122).
Green LED: it turns on to signal the detection activity of the microwave section.
ALARM MEMORY
This function allows to identify which detector has generated an alarm.
To enable the alarm memory, connect the input "M" to the output "+INT" of the antitheft control station.
Red LED operation (alarm memory)
Slow flashing (5 sec.): insertion.
Quick flashing: signalling of the sensor detection with active alarm memory.
Acceso fisso: Fixed light: signalling of the sensor detection without active alarm memory.
NOTE: The alarm memory cancellation occurs automatically after 5 seconds from the system insertion.
The activation occurs after 15 seconds of delay from the system insertion.
