The S21 multisensor detector contains a photoelectric smoke detector and thermistor temperature sensor whose outputs are combined give the final analog value to the ALM3-IP
Multisensor
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 signals from the photoelectric smoke sensing element and the temperature sensor are independent, and represent the smoke level and the air temperature in the vicinity of the detector. The detectors micro controller processes the two signals. The temperature signal processing extracts only rate of rise information for combination with the optical signal. The S21 Multisensor is not a fixed temperature heat detector.
- DET2105 – S21 Multisensor Detector
- Sleek, non-fading white polycarbonate enclosure
- Zero insertion force base
- Multisensor reduces need for use of ionization detectors
- Maintains own drift-compensation values on smoke sensor portion to keep sensing window open and nuisance alarms eliminated
- Alarm flag sends signal to system even when device is not being interrogated
- True multi-criterion detector evaluates combined signals from ROR heat sensing element and smoke sensing element
- Dual LED’s for 360 degree visibility
- Wide variety of addressable input/output devices
- Relay and synchronized temporal sounder bases
- Line isolators and isolator bases also available
- RoHS Compliant
The contractor shall furnish and install, where indicated on the plans, addressable multisensor smoke detectors with one of the several addressable mounting base options available. The detector base will contain the patented XPERT programming card which will permit the free interchange of sensor heads without requiring additional programming of the detector head or attached base. The intelligent detector shall be capable of drift compensation adjustments, and contain dual integral LED’s which will flash intermittently when polled and shall latch when the unit goes into Alarm. The multisensor detector head shall combine the signal from the heat sensing thermistor in a rate-of-rise fashion with the analog value readings from the photoelectric smoke sensing chamber for optimum protection from smoldering and flaming fires. 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 multisensor detector shall be the Harding part number DET2105.
