The advanced S22 Photo sensor manages its own automatic drift compensation, accelerating overall system performance by offloading the management of the sensor compensation values from the ALM3-IP to the S22 Photo
Photo 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.
Compensation by the S22 Photo Sensor is made to adjust the detector for the infiltration and accumulation of dirt and dust over time. By compensating the detector alarm thresholds the sensing window is adjusted to remain at original factory specifications.
In addition to self-compensating algorithms, the S22 Photo has five pre-programmed user settings that may be accessed and changed from the Harding network control.
Further, the pre-programmed settings are utilized in establishing the automatic sensitivity values in place with the Day/Night sensitivity programming.
- DET2204 – S22 Photoelectric Smoke Detector
- Improved detection capabilities with smoldering, smoky fires
- Series 22 detectors distribute intelligence across the installed system
- Patented infrared smoke sensing design
- Sleek, non-fading white polycarbonate enclosure
- Zero insertion force base
- 5 user selectable modes
- Powerful transient rejection algorithms
- Conventional device mode
- Patented XPert 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 photoelectric smoke 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 detector shall be self-compensating, 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 sensitivity settings of the individual 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 the Harding network fire controls. The detector base shall be installed without regard to wire polarity. The photoelectric detector shall be the Harding part number DET2104.
