Numens - Model HNC-310-H2 - UL and EN approved non-addressable heat detectors
The HNC-310-H2 non-addressable heat detectors are suitable for connection to 2-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 . An electronic thermistor sensor provides sensitive rate-of-rise alarm operation, or fixed-temperature operation when the response threshold value is exceeded. The HNC-310-H2 range of non-addressable detectors provide fire detection and alarm system designers with a Standards-compliant, economical heat detector for property protection applications where smoke or multi-sensor detectors may not suitable due to environmental conditions.· Advanced algorithms provide excellent detection discrimination
· Durable sensor. No adjustment or replacement required
· Surface-mount device (SMD) circuit board designfor stable and reliable operation
· Dual LEDs for 360° visibility
· 2-wire models for DC 12 V and DC 24 V operation
· Connects to zone monitor for use with addressable control and indicating equipment
· Easy installation. No programming required
· Sleek low-profile housing design
· Low maintenance
