Strobe Light User’s Guide
ATTENTION! The model SL177 and SL177i strobe lights are designed to notify hearing
impaired individuals of impending danger, they have no detection means and MUST be
used in conjunction with operating Smoke, Heat, or Carbon Monoxide Alarms.
The model SL177i AC wire-in Strobe light can be directly interconnected with Kidde
Safety 3-wire Smoke, Heat and CO alarms. It will produce an intermittent flash pattern
(approximately 4 flashes, followed by approximately 5 seconds off) when triggered by a
Carbon Monoxide alarm and a steady flash when triggered by a smoke or heat alarm.
The model SL177 is a 2-wire device that can be used to add strobe light capabilities to
existing alarm systems produced by other manufacturers. A relay module or suitable
switching device ( not included), which is compatible with the alarm system will be
needed to energize the strobe light. Consult the alarm manufacturer to obtain the proper switching device for your specific alarm model.
Thank you for purchasing this strobe light. It is an important part of your family’s home
safety plan. You can trust KIDDE Safety to provide the highest quality safety products.
We know you expect nothing less when the lives of your family are at stake.

2. APPLICATIONS
PRIMARY DIRECT AND INDIRECT VISIBLE SIGNAL
Locate the strobe light on the ceiling in the center of the room or on
the wall a minimum of 80"(2 m) above the floor.
For rooms larger than 250 sq. ft. (14 ft. by 16 ft. - 4.27m by 4.88 m) the
notification device should be located within 16 ft. (4.88m) of the pillow.
SUPPLEMENTARY VISIBLE SIGNAL
The strobe may be located less than 80" (2 m) above the floor.
3. RECOMMENDED LOCATIONS OF VISUAL SIGNALING DEVICES
• Locate the first strobe light in the bedroom in which the hearing impaired
individual sleeps. If the bedroom door is kept closed at night, an interconnecting smoke detector must also be installed in that bedroom.
• Locate additional strobe lights in any lived-in room where a hearing impaired
individual would need to be notified of an alarm condition.
4. LOCATIONS TO AVOID
• In direct sunlight or high ambient light areas; the bright light may reduce ones
ability to notice the strobe light.
• In areas where the temperature may fall below 32˚F (4.4˚C) or rise above 100˚F
(37.8˚C).
• In areas with high humidity.
• Avoid outdoor locations (This device is not listed for outdoor use).
5. INSTALLATION INSTRUCTIONS
READ CAREFULLY – WIRING REQUIREMENTS
• This smoke alarm should be installed on a U.L. listed or recognized junction
box. All connections should be made by a qualified electrician and all wiring
used shall be in accordance with articles 210 and 300.3(B) of the U.S. National
Electrical Code ANSI/NFPA 70, NFPA 72 and/or any other codes having jurisdiction in your area. The multiple station interconnect wiring to the alarms must
be run in the same raceway or cable as the AC power wiring. In addition, the
resistance of the interconnect wiring shall be a maximum of 10 ohms.
• The appropriate power source is 110-130 Volts AC single phase supplied from
a non-switched circuit, which is not protected by a ground fault interrupter.
MODEL SL177i WIRING INSTRUCTIONS: For AC QUICK CONNECT 3 WIRE HARNESS.
WARNING: This alarm cannot be operated from power derived from a square
wave, modified square wave or modified sine wave inverter. These type of
inverters are sometimes used to supply power to the structure in off grid installations, such as solar or wind derived power sources. These power sources produce high peak voltages that will damage the alarm.
CAUTION! TURN OFF THE MAIN POWER TO THE CIRCUIT BEFORE WIRING
THE STROBE LIGHT.
1. When Strobe lights and alarms are interconnected, all the interconnected
devices must be powered from the same circuit.
2. A maximum of 24 Kidde Safety devices may be interconnected in a multiple sta-
tion arrangement. The interconnect system should not exceed the NFP
connect limits of 12 smoke alarms and/or 18 alarms total (smoke, heat, Carbon
Monoxide, etc). With 18 interconnected alarms it is still possible to interconnect
up to a total of 6 remote signaling devices and/or relay modules.
NOTE: WHEN MIXING MODELS WHICH HAVE BATTERY BACKUP (1275,
1275CA, 1276, 1276CA, 1285, 1296, i12040, i12040CA, i12060, i12060CA,
i12080, PE120, PE120CA, PI2000, PI2000CA, KN-COSM-IB, KN-COSM-IBCA, RFSM-ACDC, HD135F, HD135FCA, KN-COB-IC, KN-COB-IC-CA, KN-COP-IC, KNCOP-IC-CA) WITH MODELS WITHOUT BATTERY BACKUP (1235, 1235CA,
i12020, i12020CA, KN-COSM-I, KN-COSM-ICA, KN-COB-ICB-CA, CO120X,

MOUNTING INSTRUCTIONS:
• A trim ring is provided on the back of the strobe light. This trim ring is
installed on the electrical box between the electrical box and the strobe light.
• Remove the trim ring from the back of the strobe light by holding the trim
ring and twisting the strobe light in the direction indicated by the "OFF"
arrow on the cover.
CAUTION THIS UNIT IS SEALED. THE COVER IS NOT REMOVABLE! After selecting
the proper strobe light location as described in section 3, and wiring the AC
QUICK CONNECT harness as described in the WIRING INSTRUCTIONS, attach the
trim ring to the electrical box (see fig. 3).

FIGURE 3: SELECT PROPER MOUNTING HOLES ON THE TRIM RING
• Use a screwdriver to punch out only the pair of holes in the trim ring that
match your type of electrical box or plaster ring. Mount the trim ring to the
electrical box using the appropriate holes. NOTE: Use the circle, square, and
octagon markings near each mounting hole in the trim ring to help you select
the correct mounting holes (see fig. 3).
• Pull the AC QUICK CONNECTOR through the center hole in the ring and
mount the ring, making sure that the mounting screws are positioned in the
small ends of the keyholes before tightening the screws (see fig. 3).
• Plug the AC QUICK CONNECTOR into the back of the strobe light, (see fig. 4)
making sure that the locks on the connector snap into place.

• If you have finished all the WIRING AND TRIM RING MOUNTING STEPS, you
can install the strobe light on the trim ring. Alignment marks are provided on
the side of the strobe light and on the Install the strobe light on the trim ring
with the indicating marks aligned and rotate the detector in the direction of
the ON arrow on the cover until the strobe light snaps in place. (See fig. 5)
• Turn on the AC power, The model SL177i strobe light has a green AC power
on indicator which should be lit when the strobe is operating from AC power.
TAMPER RESIST LOCKING PIN: To make your strobe light tamper resistant a locking pin has been provided with your strobe light. Using this pin will help deter
individuals from removing the strobe light from the trim ring. To use the pin
insert it into the hole in the side of the strobe light after the strobe light has
been installed on the trim ring (see fig. 6). NOTE: The tamper resist pin will have
to be removed in order to remove the strobe light. This can be done easily with
a long nose pliers. Using the long nose pliers, pull the pin out of the hole, it is
now possible to remove the strobe light from the trim ring.
After installation TEST your strobe light by following the test procedure outlined
in section 6.
CAUTION! Early warning fire detection and visual notification is best achieved by
the installation of fire detection and visual notification equipment in all rooms
and areas of the household as follows: A smoke alarm and visual notification
