Each value in the above table represents the maximum wir-
ing distance (one way) when DC12V or DC24V power source
is used.
When installing 2 or more sets on one wire, the maximum
length is obtained by dividing the maximum wire length given
above by the number of sets installed.
When using a thicker than AWG19 or
φ
0.9 wire, use relays
for connection. It is not possible to connect directly to the
terminal inside of the detector.

3. EXAMPLE
CAUTION
Do not use aerial wiring, or malfunction may re-
sult.
Be sure to cover outdoor wiring with pipes, or an
electrical shock or failure may occur.
Be sure to turn off the power during the wiring
work, or an electrical shock or failure may occur.

BEAM SPREAD
As the beam has spreads, an optical path is formed when it is reflected against the nearby (highly reflective) wall or the like,
thereby alarm output may be prevented even if the beam from the transmitter to the receiver is interrupted. When a multiple
number of detectors are installed, the beam from another detector may affect and cause malfunction.
The beam spread angle of this unit is about
±
1
°
. Refer to the figure and table below to determine the installation position and
distance to be used when installing a multiple number of units.
