Product Description
UL approved conventional photoelectrics smoke and heat detector 

All of the Sentek's SD119 series detectors meet the requirements of  UL268 and EN54-5/7 for use in fire alarm signaling systems.are intrnded for use in 2-wire/4-wire Class A or B supervised zone corcuits.The SD119 series detectors are subject to panel compatibility limits and compaliance with corresponding NFPA 72E standards,local codes,and ordinances.
The SD119 include 2-wire and 4-wire detectors,which provide fast and reliable response for photoelectric smoke and heat(135 °F) detection.While the somke and heat detection circuits operate independently,their outputs being "OR"connected,The Sentek's SD119 series detectors provide the fire detection performance by acting as a smoke sensor and/or a 135 °F heat detector at the same location.

Product Features:
1)  2 or 4 wire models
2)  Advanced detection and discrimination algorithms 
3)  Easy installation and maintenance
4)  Sleek low-profile housing design
5)  Durable sensor head, no need for replacement 
6)  SMD circuit board design: satisfactory quality and reliability guaranteed
7)  Intrgrated heat detector for SD119-2H and SD119-4H models
8)  N/C (normal / close) and N/O (normal / open) relay output  
10) AR (auto reset) function for security systems ( option for 4 wire models) Sensor base option:standard and Shottky Diode
11)  Five-year warranty
