S22 heat detectors have a common profile with the photo and ion smoke sensors but have a low air flow resistance case made of self-extinguishing white polycarbonate
Heat Sensor
Distributed Architecture
All FC-250 modules operate independently. There is no central operating system, no central point of failure. Processing power is distributed throughout the campus, increasing system survivability, eliminating home-run wiring costs while decreasing downtime due to system maintenance.
Highly Survivable
Since NAC’s and SLC’s are grouped on the same module and events are processed locally, ALM modules will perform local operations even if network communication has been severed. Distributed modules also minimize campus-wide downtime by restricting maintenance to the local module.
The S22 heat detector uses a single thermistor to sense the air temperature at the detector position. The thermistor is connected in a resistor network, which produces a voltage output dependent on temperature.
The S22 Heat Sensor has five pre-programmed user settings that may be accessed and changed from the Harding network fire control. Further, the pre-programmed settings are utilized in establishing the automatic temperature response values in place with Day/Night sensitivity programming.
- DET2201 – S22 Heat Detector
- Series 22 detectors distribute intelligence across the installed system
- Sleek, non-fading white polycarbonate enclosure
- Zero insertion force base
- 5 user selectable modes combine static response with rate-of-rise features
- Powerful transient rejection algorithms
- Conventional device mode
- Patented programming card eliminates addressing errors during system installation and maintenance
- Alarm flag sends signal to system even when device is not being interrogated
- Wide variety of addressable input/output devices
- Relay and synchronized temporal sounder bases
- RoHS Compliant
The contractor shall furnish and install, where indicated on the plans, intelligent heat detectors with one of the several addressable mounting base options available. The detector base will contain the patented programming card which will permit the free interchange of sensor heads without requiring additional programming of the detector head or attached base. The intelligent heat detector shall be self-reporting and contain dual integral LED’s which will flash intermittently when polled and shall latch when the unit goes into Alarm. The detector head shall have 5 programmable settings that can be accessed automatically or by manual setting from the fire control which will allow the detector several response modes of the individual heat detector to be modified as required. The combination of the detector head and twist lock mounting base shall be UL/ULC listed and UL/ULC listed as compatible with Harding network fire controls. The detector base shall be installed without regard to wire polarity. The heat detector shall be the Harding part number DET2201.
