MOUNTING
INSTRUCTIONS
Each 4192SDM
detector is supplied with a mounting
bracket kit that permits the detector to be mounted
using several
techniques.
1. Units maybe mounted directly to a 3-inch or 4-inch, 1-1/2-inch deep octagonal electrical box using the supphed mount-
ingbracket
(See Figuresl
and 2).
2. Units maybe
mounted to a 4-inch square electrical box by using a plaster ring with the supplied mounting bracket.
3. Units maybe mounted directly to the ceiling using the plastic screw anchors packed with the bracket. For direct mount-
ing, the bracket is used asatemplate
and 3/16-inch
holes aredri[led
forthe
screw anchors.
TAMPER
RESISTANCE
This detector
includes atamper-resistant
feature that prevents itsremova[
from the base without the useofatool.
To
enable this feature, remove the smaller tab by breaking it at the sctibed line on the tamper resistant tab before installing
the detector. The tamper resistant tab is on the detector
mounting base.
Toremove
atamper-resistant
detector from the base, usea
pocket screwdriver,
orsimilar
tool, todepress
the tamper-
resistant tab and turn the detector counterclockwise.
The tab is accessible through the slot on the mounting
base.
WIRING INSTALLATION

A78- , %%0,
For signal wiring (the wiring between interconnected
detectors),
it is recommended
that the wire be no smaller than 22
gauge in cross sectional area. However, the screws and clamping plate in the base can accommodate
wire sizes up to 12
gauge (2.5 square mm). The use of tilsted
pair wiring or shielded cable for the power (+ and -) loop is recommended
to
minimize theeffects
of electrical interference.
If shielded cable is used, the shield connection to and from the detector must be continuous
by using wire nuts, crimping,
or soldering,
as appropriate,
for a reliable connection.
Locate installations
where normal ambient temperatures
do not exceed 120°F.
Make connections
by stripping about 3/8 (10 mm) of insulation from the end of the wire. Then, slide the wire under the
clamping plate andtighten
theclamping
plate screw. Do NOT!o~p \\,ires around tha terminal.

DETECTOR
ID NO.
The detector is addressed via a unique internal setial number sequentially
stored in the detector's special circuits
Refer
to the supporting Ademco control panel installation instructions for the appropriate
information.
TESTING
Note: Before testing, notify the proper authorities that the smoke detector system ;s undergoing
maintenance
and, there-
fore, will be temporarily
out of service. Disable the s),stem undergoing maintenance
to prevent unwanted alarms,
Note: Before testing thedetector,
check forthepresence
of?heblinting
LED. Ifitdoes
not blink, power has been lost to
the detector (check the wiring) or it is defective
(return for repair).
Detectors must be tested after installation and periodic maintenance.
Test the 4192SDM
as follows:
A. Test Switch
1. Press andhold
thetestswitch
for5 seconds.
2. An alarm should be annunciated
at the system's control or console within 5 seconds. Some systems also cause the
detector's
LEO to latch on during the alarm. Othemise,
the LED continues to blink every 10 seconds,
