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

Installation
Place the detector into the detector base. Turn the detec-
tor 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 remove
the detector 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 detector
to be rotated counterclockwise for removal. NOTE: The
decorative ring must be removed in order to remove the
head when using the tamper-proof feature.
The tamper-proof feature may be defeated permanently
by breaking the plastic lever off the base.
Note: The number of two-wire smoke detectors which can
be accommodated per zone varies with different control
panels. Consult the control panel instruction 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 per-
formed 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.
Cleaning programs should be adapted to the individual
environment in conformance with NFPA Standard 72. We
recommend at 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 procedure, refer to the Instal-
lation and Maintenance instructions furnished with each
detector.
