DO'S AND DON'T'S
Install the sensor in a location
●
such that intruders are more likely
to cross the protection zones,
rather than approach head on.
[MAINTENANCE]
1.When the unit is soiled, clean the cover with a soft cloth
moistened with a small amount of cleansing -solution. Do not
use chemicals such as thinners or alcohol.
2.Check operation once a week. Do not fail to check operation
whenever furniture in coverage area is moved.

variations caused by the presence of a human body. Therefore,
note that similar variations in conditions in protection area, due
to other reasons, may cause the sensor to create an alarm as it is
unable to distinguish between sources.
【Basic connection】
[ When two units are used ]
【Allowable wiring distance between sensor and power source】
Size of wire used
AWG 22 (Dia. 0.65mm)
AWG 20 (Dia. 0.80mm)
AWG 18 (Dia. 1.00mm)
Note 1) The maximum wire length, when two or more units are connected, is
the above distance divided by the number of units.
2) The protection circuit can be wired to a distance of 3,280 ft (1,000m)
with AWG 22 (0.65mm dia.) wire.
＊Allow approx. one minute for warm-up after power is applied. (Alarm
LED is flashing) In the meantime, an alarm is not initiated.
＊After the one minute has passed the unit will be in the armed condition
and will trigger when detecting a human body.
＊All wiring should be in accordance with the national electric code NFPA-70.
Do not install the sensor outdoors
●
(indoor only).
(6) When sensor unit is detached, hold
it and slide release lever as
illustrated.
(7) When sensor unit is locked,
tighten the locking screw.
