INSTALLATION AND MAINTENANCE INSTRUCTIONS
SD-100 Series Photoelectric Smoke Detectors
GENERAL DESCRIPTION
• Model SD-100-2WT: 2-Wire Photoelectric Smoke Detector with Heat
Sensor and Remote Indicator
• Model SD-100-4WT: 4-Wire Photoelectric Smoke Detector with Heat
Sensor
• Model SD-100-2WP: 2-Wire Photoelectric Smoke Detector with
Remote Indicator
• Model SD-100-4WP: 4-Wire Photoelectric Smoke Detector
All models incorporate a microprocessor with an advanced optical sensing
chamber. Models SD-100-2WT and SD-100-4WT feature a restorable,
fixed temperature (135°F/57.2°C) thermal detector. SD-100 Series
detectors are designed to provide open area protection.

MISE EN GARDE: POUR LE CONTRÔLE DES SYSTÈMES – POUR
LES BORNES 2 ET 5, NE PAS UTILISER DE FIL ENROULÉ SOUS LES
BORNES. COUPER LE CÂBLAGE POUR ASSURER LA
SURVEILLANCE DES RACCORDEMENTS.
TO PREVENT DETECTOR CONTAMINATION AND SUBSEQUENT WARRANTY
CANCELLATION, THE SMOKE DETECTOR MUST REMAIN COVERED UNTIL
AREA IS CLEAN AND DUST FREE.
AVERTISSEMENT
POUR ÉVITER LA CONTAMINATION DU DÉTECTEUR ET ANNULER LA
GARANTIE, LE DÉTECTEUR DE FUMÉE DOIT RESTER COUVERT TANDIS
QUE L'ENDROIT EST PROPRE ET SANS CONTAMINER DES POUSSIÈRE.

WARNING
INSTALLING THE BASE
FIGURE 3:
Notes: The end-of-line devices shown in Figures 1 and 2 must be
compatible with the control panel. The end-of-line supervisory relay must
be rated for the DC power voltage used.
Open area smoke detectors are intended for mounting on a ceiling or a
wall in accordance with the fire standard in your country.
There is a limit of 21 smoke detectors on one loop.
1. Ensure that all wires are properly identified, and fasten the wires
away from the connector terminals.
2. If you used a jumper wire to connect the poles of terminals 2 and 5
when testing the detector loop continuity, remove the jumper wire
before you install the detector head.
3. Mount the base of the smoke detector directly onto an electrical
junction box such as an octagonal (3", 3.5" or 4"), a round (3"), or a
square (4") box without using any type of mechanical adapter.
INSTALLING THE HEAD
1. Thoroughly clean the area of construction debris and dust.
2. Align the mark on the detector head with the short mark on the base
and twist the head clockwise to secure it. The mark on the head
should line up with the long mark on the base.
