Failure to properly install, test, and maintain a
smoke detector system may cause it to fail resulting
in loss of life and/or property.
WARNING
!
The detector provides the following features:
Detector/base lock
discourages unauthorized removal of
the detector by requiring a screwdriver to remove the
detector from the base.
Mounting base
mounts directly to standard single-gang, 3-
inch round or 4-inch octagonal electrical boxes. Can also
be mounted directly to walls and ceilings if the local
authority having jurisdiction allows.
Selecting a Location
Selecting a suitable location is critical to the operation of
smoke detectors. This equipment should be installed in
accordance with the National Fire Protection Associations
(NFPA) Standard 72.
Important:
Regulations pertaining to detector installation
vary from state to state. For more information, contact
your local fire department or local authority having juris-
diction.
In addition to NFPA 72, use the following location guide-
lines to optimize performance and reduce the chance of
false alarms from the detector:
Locate ceiling-mounted smoke detectors in the center of
a room or hallway at least 4 inches from any walls or
partitions.
Locate wall-mounted smoke detectors so the top of the
detector is 4 to 12 inches below the ceiling.
DO NOT
locate detectors in or near bathrooms or
kitchens.
Locate in a suitable environment as follows:
-
Temperature between 32°F (0°C) and 100°F (37.8°C)
- Humidity between 0 and 95% non-condensing
Locate away from air conditioners, heating registers and
any other ventilation source that may interfere with
smoke entering the detector.
Mount smoke detectors on a firm permanent surface.
Installing the Detector
All wiring must conform to the National Electric Code
(NEC) and/or local codes having jurisdiction. Use 12 to
24 AWG wire to install the detector.
1. If you are using the detector/base lock, remove the
detector knockout and break off the tab on the mounting
base. See Figure 1.
2. Remove the red plastic dust cover from the detector.
The detector is shipped with a dust cover for protection
on construction sites with dusty environments.
3. Run system wiring to the detector location and mount
electrical boxes if necessary.
4. Line up and attach the gasket and mounting base to the
electrical box, wall, or ceiling using the screws pro-
vided. Use the wall anchors if necessary. See Figure 2.
5. Strip the system wires and connect them to the appropri-
ate terminals on the detector. See Figure 3.
