Detector Installation Method
* Make sure that the main power breaker is turned OFF and that alarm contact signal lines are open.
Follow the procedure below to check detector installation, setting (adjustment) and operations.
(1) Installing detecting box
Remove the outer cover. Using a flat-blade driver or similar tool, open the notches below the outer
cover and remove it.
Remove the intermediate board. Loosen four M4 flat-head screws and remove the intermediate board
(with circuit board) from the enclosure.
* To install a detector in the wall-embedded scheme, refer to: Method of Installing the Wall-embedded Type.
Work on the enclosure. Decide wire insertion points and work on the enclosure for inserting wires as
need arises.
Install the enclosure. Using the mounting holes (four 5–mm-diameter holes) on the back of the
enclosure, fix it in place.
(2) Wiring the power supply, sensor, and alarm contact signal lines.
Insert wires into the enclosure. Using the back of the wall, wire protectors, or conduits, insert wires into
the enclosure.
Attach crimp contacts to wires. By aligning the intermediate board (with circuit board) on the enclosure,
adjust wire lengths.
Note 1: Use crimp contacts 7.5 mm or less in diameter for use with an M3 or M4 screw.
Note 2: Use crimp pliers matching the crimp contacts and wire size used.
Connect wires to the circuit board. Make secure connections according to the “terminal description” as
shown below, using a flat-blade screwdriver.
To improve noiseproof properties and resistance to static electricity, be sure to make grounding
connections.
Note 1: Bend crimp contacts about 45˚ as shown in “cross section.”

(3) Setting (adjustment) and checking
Checking settings: To change a setting, follow the instructions under: Detector Setting Method.
Checking of operations: To check operations at time of installation, refer to: Method of Operating
Detector and Checking Detector Operations.
(4) Completion of installation
Attaching the insulating sheet: Align the line on the insulating sheet to the terminal block and attach the
sheet.
Fitting outer cover: After making sure that LEDs are not bent, attach outer cover.
Checking operations after installation: When postponing the operation test due to power supply
condition or other situations, remove the outer cover and follow the instructions under: Method of
Operating Detector and Checking Detector Operations for Testing.
Method of Installing Wall-embedded Type
This detector can be installed in a wall-embedded finish after removal from enclosure.
Refer to illustrations below to install detector using standard switch box, clamp fittings and retaining
fittings.
