LOCATION
DETECT-A-FIRE detectors are precision temperature sensors.
They must be mounted in an area (normally a ceiling) so that:
1. The detector spacing complies with both system
requirements and requirements of the agency having
local jurisdiction.
2. The thermal air path to the shell is not obstructed.
Spacing per UL, FM, and UL of Canada is shown in Table 1.
Distances given are for between units on smooth ceilings.
Distances from partitions or walls are half that shown.
To assure that all spacing requirements are met, consult
the authority having local jurisdiction.
MOUNTING
DETECT-A-FIRE units are not position sensitive. Horizontal
and vertical detectors refer to the most common mounting
configurations for that unit. However, each type can be
mounted either horizontally or vertically depending on the
application and installation requirements.
*Although incandescent lamps are considered resistive, their inrush
current is 10 -15 times their steady current. Do not exceed ratings.

These detectors are provided with a surface mount adaptor
which may be mounted on a ceiling or to an outlet box.
However, if the adaptor is direct ceiling mounted, CIRCUIT
VOLTAGE MUST BE LIMITED TO 30 VOLTS.
The Canadian Electrical Code, Part 1, requires that these
devices be installed, mounted to an approved outlet box
and connected to Class 1 wiring. Surface mount units shall
be used only in this manner for Canadian approval.
For direct ceiling mount, proceed as follows:
1. The knockouts are located on the side of the surface
mount adaptor. Remove appropriate knockouts and
install rubber grommets.
2. Mount adaptor to solid ceiling surface through slotted holde in
adaptor mounting brackets. Supplied insulator gasket should
be placed between ceiling and adaptor. Adaptor may be
rotated to position detector.
3. Run system wiring through rubber grommets and connect
to terminals on detector per Figure 3 observing applicable
electrical codes.
4. Mount detector to adaptor with two #8-32 screws supplied.
For optional outlet box mount, proceed as follows:
1. Bend the mounting brackets on the supplied adaptor to fit
standard 4-including outlet box.
2. Mount adaptor to solid ceiling surface through slotted holes in
adaptor mounting brackets. Supplied insulator gasket should
be placed between ceiling adaptor. Adaptor may be rotated to
position detector.

1. In order to function properly, the sensing shell of the unit must
remain free from paint, grease, oil, etc. Should such a build up
occur, DO NOT, under any circumstances, attempt to remove it.
Replace the unit.
2. Detectors mounted in an area subject to physical abuse or damage,
other than above, must be suitable protected without obstruction the
thermal airpath to the unit.
3. Do not install the unit where the shell would be physically
damaged by sand, grain, rocks, etc.
4. Any detector that has been involved in a fire, abused
or damaged must be replaced.
5. Consult the factory for special precautions necessary
for outdoor use or moist environments.
ANY OF THE ABOVE COULD CHANGE THE FACTORY
TEMPERATURE SETTING, WHICH MAY RESULT IN PROPERTY
DAMAGE AND/OR PERSONAL INJURY OR DEATH.
IT IS POSSIBLE FOR A UNIT TO HAVE BEEN ABUSED OR
DAMAGED AND NOT DISPLAY ANY OUTWARD INDICATION OF
THE DAMAGE. ALL UNITS SHOULD BE TESTED PERIODICALLY
IN ACCORDANCE WITH NATIONAL FIRE PROTECTION
ASSOCIATION REQUIREMENTS (72e) OR THE AGENCY HAVING
LOCAL JURISDICTION.
WARNINGS
INSTALLATION (continued)
3. Run system wiring through rubber grommets and connect
to terminals on detector per Figure 3 observing applicable
electrical codes.
4. Mount detector to adaptor with two #8-32 screws supplied.
For optional outlet box mount, proceed as follows:
1. Bend the mounting brackets on the supplied adaptor to fit
standard 4-inch outlet box.
2. Mount adaptor to outlet box through two slotted holes in
adaptor mounting brackets. Adaptor may be rotated to
position detector.
3. Connect system wiring to terminals on detector per Figure 3
observing applicable electrical codes.
4. Mount detector to adaptor with two #8-32 screws supplied.
1. It is recommended that a standard 4-inch outlet box be
used to mount the detector. Care should be taken that a
neat 4-inch diameter hole be cut in ceiling to allow mounting
clearance for detector. An oversized or ragged hole may
show around the mounted unit.
2. Attach supplied flush mount adaptor to outlet box. Adaptor
may be rotated in screw slots to position detectors as desired.
3. Connect system wiring to terminals on detector per Figure 3
observing applicable electrical codes.
4. Mount detector to adaptor with two #8-32 screws supplied.
