MOUNTING
·
On a 4-inch square box with or without plaster
ring. Minimum depth 1.5 inches.
·
On a 3.5-inch octagonal box. Minimum 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.
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.
TESTING
Detectors may be tested in the following ways:
·
Place a test magnet against the detector
as directed in the installation instructions.
The detector should go into alarm within
30 seconds.
·
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 detector.
MAINTENANCE
Cleaning programs should be adapted to the individ-
ual environment. We recommend at least an annual
cleaning of the unit. The detector screen and cover as-
sembly can be removed, revealing the sensing cham-
ber. A vacuum cleaner can be used to remove dust from
the screen, cover and sensing chamber. For the com-
plete procedure, refer to the Installation and Mainte-
nance Instructions furnished with each detector.
