1. FEATURES OF THIS PRODUCT
2. BEFORE USE
WARNING
CAUTION
● Sensitivity Compensation Function to Keep Stable Function
: The detector sensitivity is automatically compensated and adjusted even in
case that the level of the light received by the light receiver is decreased due
to contamination on the detector lens surface.
● Light Axis Adjustment without Voltmeter (Tester)
: Light output can be checked by means of the light emitting pattern of the
indicator lamps, without using a voltmeter.
● Easy Installation
: This product can be installed as an unit with the assembled state by
changing the assembling Combination of the base, the cover and the body
depending on the installation site conditions.
● To use this product safely, this operating manual contains various cautions.

3. CAUTIONS FOR USE
● Where it is directly exposed to rain or water.
● Where smoke or mist is usually generated.
● Where the light receiver is subjected to direct sunlight or strong
illumination light.
● Where the ambient temperature is lowered below -10°C or
exceeds 50°C.
● Where the mounting position of the detector is subjected to
vibration or strain. (Install the detector on a rigid position such as a
support/pillar of the main structure.)
● Where it is difficult to perform maintenance and inspection.(Space
of 50cm in vertical and horizontal directions (50cm each in
left/right/up/down directions) is required for surrounding of the
detector. In case that the ceiling height is 2.5 m or lower, pay
attention to the upper space. Example: If the ceiling height is
2.1m, the upper space is to be 42cm.)
● Where the light axis (between the light transmitter and receiver)
may be interrupted due to transportation of objects or a
transparent obstacle such as glass.
● In a place where a ball or a bar is usually used, such as
gymnasium, apply the protective cover (Model FZP014).
As this product is not of outdoor type, DO NOT install it in any of the following
places. (If installed, it may cause a malfunction or abnormal operation.)
Space for a screwdriver is required in the
above of the detector.
Prohi-
bition
Installation Standard :

Transmitter and Receiver)
View the mirror through the viewing hole, and turn the light axis adjusting
screw(s) (vertically and/or horizontally) so that opposing light receiver
(viewed from the transmitter) and the opposing JIS box (viewed from the
receiver) may be located in the viewing hole.

When the heater (for preventing dew condensation) is energized,
it becomes hot (about 60°C). Therefore, pay attention not to
touch it during the installation work. If touched, it may cause you
to be burnt.

11.2. Power Energization (Recommend to energize to Light Transmitter)
Connect the battery connector for detector test to the connector on the left
side of the detector (when viewed from the front of the detector), and next,
connect the battery connector for detector test to the auxiliary battery. In
this case, the Adjustment Mode alone is effective. (In case that no battery
is available, turn ON the power of the fire control panel.)
11.3. Switchover of Adjustment Mode
(Recommend to switch over Adjustment Mode on Light Transmitter)
At a lapse of about 10 seconds after power
ON, the detector
becomes operational.(In case that the power is
fed through the battery connector of the light
receiver, the green LED of the receiver lights
every 3 seconds. When the power is fed to the
light transmitter, the green LED of the receiver
does not light.
Stand at a position so that you may not
interrupt the light axis (You can see the
detector as shown on the left figure.).
Press MONITOR/ADJUST. Switch for one
second and then, release the switch, and the
indicator lamps emit lights as follows ;
※In case of the light receiver, operate the
MONITOR/ADJUST. Switch in the same way.
(Light Transmitter : Green and red LEDs light at
the same time and then, flicker alternately.)(Light
Receiver : Yellow LED flickers every one
sec.)Wait (about 4 sec.) until alternate
flickering of the indicator lamps is finished.
The power can be supplied through the battery connector of the
light transmitter or light receiver or the terminals C and L of the
light receiver. To avoid a malfunction, ensure that the power is
supplied via one route.
No adjustment can be made when the Fire Alarm Lamp on the
light receiver is lighting. In case that the power is supplied
through the battery connector of the light receiver, pull out the
battery connector and wait for about 15 seconds. Then, connect
the battery connector again.

Image of the Paragraphs 11.4 and 11.5 on Page 15 and Paragraph 12 on Page
17 is shown below.
The relationship between the light emission pattern and output of the light
transmitter in case of the light axis adjustment is as follows.
To ensure stable monitoring of the detector for long period, set the light
output to the peak as possible as you can according to the following steps
①→② (Allowance for imperfect alignment of light axis generated after
installation).
①Turn the Light Axis Adjusting Screw until green flickering of the indicator lamp
(Power Lamp) of the light transmitter becomes red on the left and right side
ends. Then, set the light axis to the center within the green flickering range.
②Adjust the light axis in the vertical direction in the same manner as stated in
the above ①

11.4. Fine Adjustment of Light Transmitter (in Horizontal Direction)
Turn the Light Axis Adjusting Screw (Horizontal), and the flickering pattern
of the green indicator lamp changes according to the condition of the
received light output.
11.6 Switchover of Monitoring Mode
If the green indicator lamp flickers after
adjusting the light axis in the vertical
and horizontal directions, press the
MONITOR/ADJUST. Switch for two
seconds or over and then,release it.
(Both the green and red indicator
lamps light at the same time.)
Adjust the light axis in the vertical
direction in the same manner as
described in the above 11.4.
11.5 Fine Adjustment of Light Transmitter (in Vertical Direction)
CAUTION
DO NOT use a motor-driven
screwdriver. If used, it may
cause the screw to be
damaged.
DO NOT interrupt the light axis during the switchover of the
Adjustment and Monitoring Modes.
Normally, the indicator lamp flickers in
green first. Turn the screw clockwise or
counterclockwise to flicker it in red.
Change flickering of the lamp in the
order of “red→green→red” and check
the range of green flickering and align
the light axis to the center of it.
Make the fine adjustment of the light axis by means of the Light Axis Adjusting
Screw so that the indicator lamp (Power Lamp) of the light transmitter flickers
only in green.
After green flickering of the indicator lamp goes out, pull out the battery
connector for detector test. In case that the power is fed through the
terminals C and L, it is not necessary to cut off the power supply of the fire
control panel.

Insufficient output of received light
:Turn the Light Axis Adjusting Screw in
the reverse direction of the above ①.
Sufficient monitoring output
:Set the light axis in the center of this
range (In case that the indicator lamp
does not flickers quickly.).
Increase in output of received light
: Set the light axis in the center of this
