INSTALLATION

Place the sensor into the sensor base. Turn the sensor

clockwise until the sensor locks into place.

To use the tamper-proof feature, break the smaller tab

on the base as shown in the installation instructions. In-

stall the sensor. To remove the sensor from the base

when using the tamper-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 sensor to be rotated counterclock-

wise for removal.

NOTE: The decorative ring must be

removed in order to remove the head when using the

tamper-proof feature.

Refer to NFPA 72, Chapter 5-3 “Smoke Sensing Fire

Detectors” for spacing, location of sensors and other

guidelines.

TESTING

Sensors may be tested locally in the following ways:

• A. Place a test magnet against the sensor housing

per the instructions. The sensor should go into

alarm within 30 seconds.

• B. Aerosol Generator - The Gemini Model 501

aerosol generator may be used to perform a

functional test. This test should be performed

immediately following the magnet test. Magnet

test initiates an approximately ten minute period

when the detector's signal processing software

routines are not active. Failure to first perform the

magnet test will introduce a time delay before the

detector alarms. Follow instructions in the

generator instruction manual.

MAINTENANCE

Cleaning programs should be adapted to the individ-

ual environment in conformance with the National Fire

Alarm Code, NFPA 72. We recommend, at the least, an

annual cleaning of the unit. The sensor screen and cover

assembly 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 sensor.
