Description of the System Sensor 22051E-IV
The System Sensor Smoke Detector 22051E is the new optical smoke detector out of the Series 200 Advanced range. The Series 200 Advanced range incorporates the new digital Series 200 Advanced Protocol which offers the possibility of having more devices on the loop and a better control, configurability and device management.
Many years of research by System Sensor result in a new revolutionary detection chamber design. This features an improved detection across multiple types of fire, improved resilience to false alarms through dust and lower risk of false alarms through insect ingress and other debris.
The 22051E System Sensor Smoke Detector incorporates two tri-colour LEDs which indicate the sensor status around the area where the detector has been mounted. The LEDs are programmable with static or blinking red, amber and green status indications available.
Each System Sensor Optical Smoke Detector (22051E-IV) gets its individual loop address assigned by the rotary decade address switches. These switches are located on the rear of the sensor. The use of decimal address codes is easy and reduces the input of incorrect addresses.
All Series 200 Advanced detectors are environmentally friendly and meet the WEEE and RoHS legislative requirements.
