5358 PHOTOELECTRIC SMOKE DETECTOR

(In Typical Application) PIN 1 (C1) A capacitor connected to this pin determines the gain of the photo amplifier during the push-to-test mode and during the chamber monitor test. A typical value for this high-gain mode is 0.047 µF but should be selected based on the photo chamber background reflecti.

5358 Features

* for a photoelectric type smoke detector. This device can be used in conjunction with an infrared photoelectric chamber to sense scattered light from smoke particles. Special features are incorporated in the design to facilitate calibration and testing of the finished detector. The device is designed
