MOUNTING
· On a 4-inch square box with or without
plaster ring or supplied adapter. Minimum
depth 1.5 inches.
· On a 3 1/2 or 4-inch octagonal box. Minimum
depth 1.5 inches.
VIEWS SHOWING POSITION OF TEST MAGNET
· On a single gang box. Min. depth 1.5 inches.
INSTALLATION
Place the detector into the detector base. Turn the de-
tector clockwise until the detector locks into place.
To use the tamper-proof feature, break the smaller tab
on the scribed line in the tamper proof tab located on the
detector mounting bracket. Install the detector. To re-
move the detector from the base when using the tam-
per-proof feature, insert the blade of a small
screwdriver into the hole on the side of the base and
push the plastic lever away from the detector head. This
will allow the detector to be rotated counterclockwise
for removal. NOTE: The decorative ring must be re-
moved in order to remove the head when using the tam-
per-proof feature.
WARNING: To prevent detector contamination
during construction, smoke detectors must be
protected from dust and contamination until area
is clean and dust free. See NFPA 72-5-3.7.1.3.
The tamper-proof feature may be defeated perma-
nently by breaking the plastic lever off the base.
NOTE: The number of two-wire smoke detectors
which can be accommodated per zone varies with dif-
ferent control panels. Consult the control panel in-
struction manual to determine the capacity.
Refer to NFPA 72, Chapter 5-3 “Smoke Sensing Fire
Detectors” for spacing, location of detectors and other
guidelines.
· Field metering of detector sensitivity may be
performed with the aid of a voltmeter and Test
Kit MOD 400R.
For the complete procedure, refer to the Installation
and Maintenance instructions furnished with each de-
tector.
TESTING
Detectors may be tested in the following ways:
· Place a test magnet against the cover opposite
the test module socket (See illustration above).
The detector should go into alarm within 5 sec-
onds.
MAINTENANCE
Cleaning programs should be adapted to the individ-
ual environment in conformance with NFPA Standard
72. We recommend, at the least, an annual cleaning of
the unit. The detector screen and cover assembly can be
removed, revealing the sensing chamber. A vacuum
cleaner can be used to remove dust from the screen,
cover and sensing chamber. For the complete proce-
dure, refer to the Installation and Maintenance instruc-
tions furnished with each detector.
· A test card with one end marked “ALARM”
and the other end marked “NO ALARM” is fur-
nished with each unit. For the complete proce-
dure, refer to the Installation and Maintenance
instructions furnished with each detector.
