Product name:
Relay output 4-wire conventional smoke and heat combined detector

SNC-300-CR detectors which provide fast and reliable response for photoelectric smoke and heat 57℃(135^oF) 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℃ (135^oF) 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.

Features:

1) 4-Wire operation

2) Optical & thermal detection

3) Built-in alarm relay

4) Wide operating voltage

5) Advanced electronic technology

6) Proven detection performance

7) UL EN approval
