A5366CA is a low -current BICMOS circuit, which provides all necessary for photoelectric smoke detectors. Features. This device can be used with the infrared photoelectric chamber to detect the scattered light of the smoke particles. Special functions are added to the design to calibrate and test the finished detector. The design of the device is in line with the specification of the insurance dealer's laboratory UL217.

Variable -increasing optical leaflets can be directly connected to infrared transmitter/detector pair. The level of amplifier gain is determined by two external capacitors, and then selects inside according to the working mode. Select low gain in standby and timer mode. During the local alarm, this low -gain (inside) increased by about 10%to reduce error triggers. Use high gains to regularly monitor the sensitivity of the chamber during the button testing and standby.

The internal oscillator and timing circuit Make the spare power supply at the minimum value by sensing the smoke every 10 seconds every 10 seconds. A special three -level acceleration sensing scheme is included in it, with a minimum of time for sound alarms and reduced error triggers. In addition, in order to send a warning signal, two consecutive cycles need to reduce the sensitivity of the chamber.

A5366CA uses a low -cost 16 -pin dual -column direct -inserted plastic packaging. Rate continuously running in the temperature range of -25 ° C to+75 ° C.
