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.
