Please make sure wiring to smoke detector as two
wire connecting arrangement.
● Please connect End-of-Line Resistor (7.5Kohm, 1/4W) to end line of smoke detectors to be
connected.
●
Maximum number of smoke detectors to be connected is 20. (0KB3 and old model 0KB/ 0IB can
be mixed.)
● Smoke detector connection terminals (L+ and C-) have polarity.
● Please use shield cables for wiring in electromagnetic disturbing environment.
● This equipment cannot be connected to detectors in automatic fire alarm system.
● Make sure to check the equipment by activating smoke detectors.
(Indication/Operation)
Fault (Trouble light: Yellow)
This turns on when detector line (L+, C－) is at
fault/short circuit and detector drop-off.
Fault is not latched at automatic reset.
② Fire Alarm (Fire light: Red)
This turns on when 2 or more detectors operate.
It remains ON until pressing Reset.
③ Detector Operated (1 detector op. light: Red)
This turns on when 1 or more detector operates.
It remains ON until pressing Reset.
④ Reset (Reset Switch) Switch to reset fire.
⑤ Power Indication (Power supply light: Green)
This turns on when power supply switch is set to ON.
⑥ Power SW (Power supply switch)
⑦ Earth Terminal（Noise reduction ）
⑧ Detector Operated (1 or more detectors operate,
C contact terminal)
⑨ Fire Alarm (Fire, C contact terminal)
⑩ L+, C－(Detector connection terminal)
⑪ DC24V or AC24V Power Line (Power input terminal)
⑫ Fault (Trouble, C contact terminal)
⑬ R+, R－(Reset input terminal)
Terminal to input reset signal from outside.
* Please use round crimp terminal with insulation coating
(RAV11.25-3) when connecting wire to terminal block.

* 1 It is recommended to use either AE cable or CPEV cable with conductor diameter over 0.65mm.
It is recommended to use shielded CPEV-S cable where electromagnetic noise causes disturbance.
Connect the shielded part of cable to the earth terminal.
* 2 After connection, please operate the detectors and confirm that the Smoke Detector Control Panel
will be restored from operating condition to normal monitoring condition by External Reset Switch input.
Non-Voltage C Contact: The labels indicate a condition when power is supplied.
