WIRING
TAMPER
Connect the "TAMPER" terminals
to a normally closed 24-hour
protection area of the control
panel. The tamper contact will
open when the cover is removed.
12V DC
Connect the 12V DC terminals to a power source of 8-16VDC,
making sure that they are connected with the correct polarity.
ALARM
Connect the "ALARM" terminals to a normally closed burglar
protection zone of the control panel. The contact will open when an
intruder is detected or during power loss.
TEST POINT (T.P.)
The T.P. is an auxiliary terminal which provides a useful means for
the technician to analyse the detector in the event of an environment
problem or a suspected faulty detector. Connect a DC voltmeter (with
minimum input impedance of 20KOhm/V) with its positive lead to the
T.P. terminal and the negative lead to the (-) 12V DC terminal as
shown in the following diagram.
The meter should read approximately 2.7V DC when no movement is detected. Any
movement into or out of the detection zone will cause the meter to deflect above or below the
2.7 volt level. Any meter variation of +/- 1V will be considered as one pulse which will
trigger an alarm output when the detector is in single-shot operation. If pulse-count operation
is selected, the detector will require a second pulse within 30 seconds after of the end of the
first pulse for the alarm to be triggered.
Using this feature during installation, the alarm contactor can learn of potential false-alarm
problems before permanent fitting of the detector.
