Description

The A5367 is a low-current, CMOS circuit providing all of the required features for an ionization-type smoke detector. A networking capability allows as many as 125 units to be interconnected so that if any unit senses smoke all units will sound their alarm. In addition, special features are incorporated to facilitate alignment and test of the finished smoke detector. The device is Recognized by Underwriters Laboratories for use in smoke alarms that comply with Standard UL217.
