Main features

  • - Compact design allows installation in limited spaces in a variety of applications.

  • - High sensitivity and high air flow resistance (Effective up to 8m/s).

  • - Generate a voted "AND" Fire Alarm (two detectors simultaneous activation) or a “SINGLE” Fire Alarm (one detector activation).

  • - Operating temperature up to 60 degree C.

  • - Automatic sensitivity compensation ensures smoke detection performance against dust accumulation.

Installation Example

Example1 (Various production equipment, large control panels, etc.)

  • Embed both the 0KB3 and the CPC-4 in the machinery that protect from a fire,　the fire signal and failure signal are transferred and output to the outside.
  • If there is a fan in the machinery, sensors should be installed near the　exhaust fan.
  • If higher reliability is required, embed two units and possible to generate fire　alarm by “AND” signal
Photo embedded in the panel
(a sensor only)

Example2 (Multiple rows of control panels, meta-clad panels, etc.)

  • One or two sensors will be embedded on each board, and the receiver will be installed at the disaster management center.
  • By using a receiver (CPC-4A) with a sensor address display function, the position of the board that detected an abnormality can be found on the receiver.
  • By using the transfer terminal equipped on each sensor, it is possible to activate patlite, relays, etc. for each sensor.
    (Separate power supply is required)

Example3 (Exhaust duct)

  • A sampling box is installed in the middle of the exhaust heat duct of the production equipment to monitor the smoke contained in the exhaust.
  • Embed a detector at a place that will surely be an air passage with considering the air flow,
  • Recommend embedding two or more sensors.
