4-Wire Combined Smoke and Heat Detector with Relay Output Function.

Model SNC-300-CR detectors which provide fast and reliable response for photoelectric smoke and heat 57℃(135oF) detection. While the smoke and heat detection circuits operate independently, their outputs being "OR' connected, and provide the fire detection performance by acting as a smoke sensor and/or a 57℃ (135oF) heat detector at the same location.

The SNC-300-CR detectors have a integral relay, connected between the 6 terminal and the 3 terminal, which provides one set of volt-free changeover (form A) contacts that change state when the detector signals an alarm.

The detector will work with most modern fire alarm control panels.

Features:

• 4-Wire operation;
• optical & thermal detection;
• built-in alarm relay;
• wide operating voltage;
• advanced electronic technology;
• proven detection performance;
• designed to meet approvals worldwide (e.g. UL LPCB CE).
