ENVIROMUX-SDS-CELC(P)
PHOTOELECTRIC SMOKE
DETECTION SENSOR
Installation Instruction
Introduction
The ENVIROMUX-SDS-CELC(P) is a smoke detection sensor intended for connection to an NTI ENVIROMUX-MICRO-T(RHP),
ENVIROMUX-16D/5D/2D, or ENVIROMUX-MINI-LXO (ENVIROMUX). When properly connected, the ENVIROMUX-SDS-CELC(P)
will provide signals to the ENVIROMUX that with proper configuration will result in alert messages being sent to users of the
ENVIROMUX. The ENVIROMUX-SDS-CELC(P) has screw terminals for easy user connections and the ENVIROMUX-SDS-CELCP
includes a 12VDC AC adapter.
This Photoelectric smoke detector (hereinafter called Detector) detects smoke using a couple of infrared diodes. The principle of
detecting is based on the fact that a granule of smoke can reflect infrared light. Infrared diodes are placed in a special chamber. The
chamber can shield external light, but doesn't prevent smoke from entering it. In the absence of smoke, the diodes can detect very
weak infrared light. As smoke enters the chamber, the diodes will receive more and more light. When the smoke reaches a certain
density, the Detector will sound out an alarm signal. In order to reduce interference and lower power consumption, the emitting circuit
uses a pulse signal. The Detector has a special structural design and ASIC, providing a dustproof, mothproof and anti-outside light
interference feature. The Detector is suitable for detecting the smoke in a house, shop, hotel, restaurant, office building, school, bank,
library, etc.
Product Features
The detector works once connected directly to DC power. A flashing LED indicates the Detector is working normally and an LED that
stays ON solid indicates an alarm condition. Normally-closed output contacts will open in an alarm condition. Connections to these
contacts are made when the Detector is secured to the mounting base.

Preparation for Installation
1. There should be no large objects that would block airflow within 0.5m (20 inches) of
the Detector.
2.
There must be no source of wind flow within 1.5m (60 inches) of the Detector.
3.
The Detector should be mounted more than 0.5m (20 inches) from any wall.
4.
The distance between two Detectors can be no less than 15m (50 feet) and the
distance between Detector and corner must he less than half of the distance between
Detectors.
5.
Always install the Detector on a horizontal surface. If it must be installed on a
slanted surface, the angle of slant must be less than 45 degrees.
6.
Clean the Detector by brushing the openings in the head with a soft brush every six months
to ensure the sensitivity and life of the product. Be sure to power OFF the Detector before
cleaning.
