INSTALLATION
①
Locate the installation site.
(Ref : 3, DO'S AND DON'T'S and
7, DETECTION AREA)
②
Slide the release lever to detach
the sensor unit.
③
Fix the base with the screws
included.

Power supply by battery.
Detach the battery cover from the back side of
(1)
sensor unit with ngers.
(2)
Put Type-AA batteries into battery case with the
correct polarity.
(3)
Plug the connector of battery case into the main
body and con rm the warm-up sound.
(4)
Put wire rst and the battery case next, into the
main body.
(5) Attach the battery cover so that the marks △ on the
cover. Face the marks ▼ on the back of the sensor.

How to use Input / Output
①Power input (terminal (1), (2))
Do not use with battery at same time.
●
Do not reverse the polarity.
●
②External output
The following either (1) or (2) output is available by connecting
open collector output terminal
output terminals.
1. Signal output (terminal (4), (5))
N/O signal is issued for a control panel etc.
When more than 2 sensors are connected on 1 circuit, make
wiring in parallel.
＋
2. Output with voltage (terminal (3), (4))
This output is not available with battery use at the same time.
1
Alarm signal is switched to power input with voltage. (Output
voltage is decreased by approx. 1V compared with input
voltage.) Within the capacity of contact output, alarm devices
(power consumption within 50mA) can be operated by this
output. This is useful for remote control of warning devices etc.
