1. Product
The Smoke Detector Control Panel is a fire detection system to be used by connecting with a designated smoke detector (0KB3).
When fire breaks out, the panel receives fire signal from smoke detector and indicates operating smoke detector address and
starts to sound buzzer alarm. Signal transfer function of non-voltage c contact is equipped with the panel. Also, the panel detects
smoke detector abnormality (sensitivity calibration limit and non-response) by regular self -diagnosis function.

ENSURE TO
COMPLY
PROHIBITED
● Do not touch the equipment with wet hands or dip into water or splash water over the equipment.
It may cause electrification or trouble.
● Do not overhaul or modify equipment.
It may cause electrification and trouble.
● Do not use the equipment in location where operating temperature exceeds its range (0-
60°C) and
where explosive gas or corrosive gas is generated.
It may cause the equipment trouble or fire ignition.
● Do not put anything into the openings.
It may cause the equipment trouble or fire.
● The installation work on AC power must be performed by a qualified person.
● Please ensure that the terminal cover of AC power supply is attached properly after completion of
work. Otherwise it may cause electric shock.
● Wire connection to each terminal should be properly carried out in accordance with specified rating
and polarity. Incorrect wiring may cause trouble or fire.
● Carry out sufficient
checking of operating condition of interlocking devices in case of test operation.
Improper operation may cause damages to the equipment or cause danger to personnel.
● The equipment is for indoor use only. Do not install it outside.
It may cause malfunction.
WARNING
● Please make sure wiring to smoke detector as two-wire connecting arrangement. (Do not connect
end-of-line resistor to end of detector line.)
● Maximum number of smoke detectors to be connected is 20. (Only 0KB3 can be connected but old model
0KB and
0IB cannot be connected.)
● Smoke detector connection terminals (L+ and C-) have polarity.
● Please use shield wire for wiring in electromagnetic disturbing environment
● This equipment cannot be connected to detectors in automatic fire alarm system.
● The Smoke Detector Control Panel is operated in normal monitoring mode [Normal] or in setting mode [AD Set
],
by confirming [Mode SW] condition at initial time (power supply switch on time or reset operation time).
Please
set to normal monitoring mode [Normal] at monitoring time and setting completion time.
If initial operation (power supply switch on or reset operation) is carried out by setting mode [AD Set
] side, fire
cannot be detected since system operates by setting mode.
● Make sure to check the equipment by activating smoke detectors.
CAUTION
Connect
earth wire
●
Make sure to connect
an
earth wire.
Otherwise it may cause electric shock during the use
of
equipment or in the event of electric leakage.
