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 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.
