Sna-360 analogue addressable photoelectric smoke detectors are microprocessor controlled state-of-the-art detectors Compatible with popular control and indicating equipment loop protocols. Advanced electronics in conjunction with a photoelectric smoke sensing chamber provides early detection of fire and High immunity against unwanted alarms. Photoelectric smoke sensor Analogue detection discrimination Dual leds for 360° visibility Dc 24 v operation 2-wire connection to many popular loop protocols Dip switch address setting 125 usable detector address settings per loop Optional remote led output
Hna-360 analogue addressable heat detectors are microprocessor controlled state-of-the-art detectors Compatible with popular control and indicating equipment loop protocols. An electronic thermistor sensor provides sensitive rate-of-rise alarm operation, or fixed-temperature operation When the response threshold value is exceeded. Durable heat sensor Analogue detection discrimination Dual leds for 360° visibility Dc 24 v operation 2-wire connection to many popular loop protocols Dip switch address setting 125 usable detector address settings per loop Optional remote led output
HNC-310 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 provides sensitive rate-of-rise operation or fixed-temperature operation when the response threshold value is exceeded. Durable heat sensor Analogue detection discrimination Dual LEDs for 360° visibility 2-wire and 4-wire models for DC 12 V and DC 24 V operation Dual LEDs for 360° visibility 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
The 4001 non-addressable control and indicating equipment forms the central part of a fire detection and alarm System.The 2-wire 4001 is compatible with numens non-addressable devices. The 4001 comes standard with features that allows flexibility and expandability. Default configuration programming Facilitates out-of-box installation and rapid commissioning. 2, 4, 8, or 16 detection zones Up to 32 non-addressable devices per alarm zone circuit Configurable non-latching alarm zones, alarm dependency (zone coincidence detection), and output delay timer 3 access levels Single-person test mode Day/night mode Manual activation of audio/visual alarm devices Supervised auxiliary dc 24 v output 2 independently programmable non-addressable a/v alarm output circuits 2 programmable fire alarm relay outputs Fault relay output 3 voltage-free inputs for remote reset, evacuation start/stop, and day/night mode Supports up to 7 repeater panels
