5347 - SMOKE DETECTOR WITH INTERCONNECT AND TIMER

Description

The A5347CA 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 an alarm. In addition, special features are incorporated to facilitate alignment and test of the finished smoke detector. This device is designed to comply with Underwriters Laboratories Specification UL217. The internal oscillator and timing circuitry keeps standby power to a minimum by powering down the device for 1.66 seconds an.
