Specifications

Addressable reflector type linear optical linear beam smoke detector
Designed to function as a component of an intelligent fire alarm system
Operates on the principle of light obscuration using an infrared beam
Suitable for protecting buildings with large open spaces, such as warehouses, atriums, etc.
Combined transmitter/receiver unit that can be connected directly to an analog loop circuit
Infrared transmitter generates a beam of light to a high-efficiency reflector
The reflector returns the beam to the receiver, where an analysis of the received signal is made
Alignment of the detector is simplified with the aid of the detector's "gunsight" aiming device
Alignment of the detector with the reflector can be "fine-tuned" with the help of a numerical signal strength indicator
Detector sensitivity can be adjusted from 25% to 50% obscuration
In addition to the four fixed-value alarm thresholds, there are two variable thresholds that automatically compensate for changes in the environment
Incorporates automatic drift compensation
Range of 70 ~ 100 meters with built-in reflector
Detector can be adjusted up to 10° vertically and horizontally for alignment
Multiple mounting attachment allows the detector to move 28° vertically and 360° horizontally when ceiling mounted or up to 23° vertically and 90° horizontally when wall mounted
200 x 230 mm reflector included for distances from 10 to 70 m, additional NOTIFIER-97 (6500-LRK) required for greater distances
Power supply: 15V ~ 32V DC (24V DC nominal)
Consumption: 2 mA (standby), 8.5 mA (max. in alarm), 20 mA (max. in alignment)
Operating temperature from -30°C ~ +55°C
Operating humidity 0% ~ 95% (non-condensing)
Degree of protection IP54
Dimensions: 190 (W) x 254 (H) x 84 mm
Weight: 1.77 kg
