Nittan EVC-P Smoke Detector Conventional Optical EVC-P Nittan

Description

Nittan EVC-P Smoke Detector Conventional Optical Nittan EVC-P Smoke Detector Conventional Optical Features: Photoelectric detector Internal 375 Ohm resistor limiting alarm current Low profile Operational voltage range from 12V to 32V Low monitoring current Omniview 360° LED (fire alarm indicator) Non-polarised terminal Remote indicator output Unauthorised head removal signal facility Standard EN54-7:2000 + A1:2002  Nittans EVC-P’s special design allows the smoke to pass through the chamber slots while the light cannot enter from the outside. It uses the light scatter method which means that a LED pulses every 8 seconds. After reaching the alarm level for the first time, the interval between this and the next pulse is automatically reduced to 4 seconds. An alarm is only given when two pulses were successful. Furthermore Nittan’s design of the EVC-P smoke detector is highly resistant against false alarms caused by air velocities, contamination or RF interference.
