mounted directly to the ceiling using the plastic screw anchors packed with the bracket. For direct mount-

ing, the bracket is used as a template and 3/16-inch holes are drilled for the screw anchors.

TAMPER RESISTANCE

This detector includes a tamper-resistant

feature that prevents its remova[ from the base without the use of a tool.

enable this feature, remove the smaller tab by breaking it at the scribed line on the tamper resistant tab before installing

the detector. The tamper resistant tab is on the detector mounting base.

To remove a tamper-resistant

detector from the base, use a pocket screwdriver,

or aimi[ar tool, to depress the tamper-

resistant tab and turn the detector counterclockwise.

The tab is accessible through the slot on the mounting baee.

WIRING INSTALLATION

GUIDELINES

All wiring must be installed in compliance

with local electrical codes and the requirements

of the authority having jurisdic-

tion.

The conductors

used to connect the smoke detectors to the control panel should be color to reduce the [ikelihood of

wiring errors. Improper connections

can prevent a system from responding

properly in the event of a fire.

For signal wiring (the wiring between interconnected

detectors),

it is recommended

that the wire be no smaller than 18

gauge (1.0 mm ) 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 twisted pair wiring or shielded cable for the power (+ and -) loop is

recommended

to minimize the effects of electrical interference.

or soldering, as appropriate,

for a reliable connection.

Make connections

by stripping about 3/8" (1 O mm) of insulation from the end of the wire. Then, slide the wire under the

clamping plate and tighten the clamping plate screw. Do NOT loop wires around the terminal.

Check the zone wiring of all bases in the system before installing detectors in them. This includes checking the wiring for

continui~,

correct polarity, and performing

a dielectric test,

The detector is addressed

via a unique internal serial number sequentially

stored in the detector's special circuits. Refer

to the suppofling

instructions for the appropriate

information.

TESTING THE 4192CPM

SENSITIVi~

Note: Before testing, notify the proper authorities

that the smoke detector system is undergoing

maintenance

and, there-

fore, will be temporarily

out of service. Disable the system undergoing

maintenance

to prevent unwanted alarms.

Note: Before testing the detector, check for the presence of the bhnking LED. If it does 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 sensitivity of the 4192CPM in the following

two

ways:

A. Test Switch

1. Press and hold the test switch for 10 seconds.

2. An alarm should be annunciated

at the system's control or console within 10 seconds, Some systems also cause the

detector's LED to latch on during the alarm. Otherwise, the LED continues to blink eve~ 10 seconds.
