https://vedardalarm.com/manual-or-auto-reset-wired-smoke-detector-relay-output-p-318
Photoelectric detector(hereinafter called detector ) detects the smoke by a couple of infrared diodes. The principle of detecting is granule in the smoke can reflect infrared light. Infrared diodes are placed in the special chamber.
The detector works once connected to DC power directly. Operation Indicator flashing signifies detector working normally and Alarming Indicator on signifies detector alarming. Built-in a couple of output contact, contact connect/disconnect after alarm. Power-down/Auto-reset when no smoke exiting nearby. Installing with mounting base.
