SNC-300 non-addressable photoelectric smoke detectors are state-of-the-art detectors suitable for connection to 2-wire or 4-wire non-addressable fire detection control and indicating equipment, or to addressable fire detection control and indicating equipment that can accept non-addressable type detectors.
Advanced electronics in conjunction with a photoelectric smoke sensing chamber provide early detection of fire and high immunity against unwanted alarms.
Features:
· Photoelectric smoke sensor
· Analogue detection discrimination
· Dual LEDs for 360° visibility
· 2-wire and 4-wire models for DC 12 V and DC 24 V operation
· 4-wire model for DC 48 V operation
· 4-wire models available with a N/O alarm relay output
· 4-wire models available with auto-reset
· 2-wire models available with remote LED output
· Connects to zone monitor for use with addressable control and indicating equipment
