A5338

A5338 Package A, 16-lead DIP Smoke Detector with Interconnect and Timer The A5338CA is a low-current, CMOS circuit providing all of the required features for an ionizationtype 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. Approximate Scale 1:1 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. Features The internal oscillator and timing circuitry keeps standby power to a minimum by powering down the Interconnect up to 125 detectors device for 1.66 seconds and sensing smoke for only Piezoelectric horn driver 10 ms. Every 24 on/off cycles, a check is made for Guard outputs for detector input low battery condition. By substituting other types of sensors, or a switch for the ionization detector, this Pulse testing for low battery very-low power device can be used in numerous other www.DataSheet4U.com Power-on reset battery-operated safety/security applications. Internal reverse battery protection The A5338CA is supplied in a low-cost, 16-pin Internal timer and control for reduced sensitivity dual in-line plastic package. It is rated for continuous Built-in hysteresis reduces false triggering operation over the temperature range of 0°C to +50°C.
