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.
WARNING
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.

INSTALLING THE BASE
Figure 2 Installing 6" base
Notes: The end-of-line devices shown in Figures 1(a) and
1(b) 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.
