GENERAL DESCRIPTION
These notification appliances offer a wide range of audible devices for life
safety notification. Our horns and chimes come with 10 field selectable
tone and volume combinations for a wide range of systems. Horns come in
two attrac-tive mounting designs, standard and compact. They are intended
for indoor applications and approved for wall and ceiling mount
installations.
These horns are public mode notification appliances intended to alert
occu-pants of a life safety event. Chimes are private mode notification
appliances used to alert trained personnel to investigate possible
emergency situations and take appropriate action. Both the horn and the
chime are listed to ANSI/UL 464 requirements.
These notification appliances are designed to be used in 12 VDC, 24VDC, or
24V FWR (full wave rectified) systems. AV devices can be activated by a
compat-ible Triga fire alarm control panel or power supply. The power
from these supplies can be either regulated or coded (pulsing) power
supplies. Refer to the appropriate fire alarm control panel manufacturer or
power supply for more information.
These wall horns and chimes come enabled with System Sensor
synchro-nization protocol which requires connections to a power supply
capable of generating the System Sensor synchronization pulses, a FACP
NAC output configured to System Sensor synchronization protocol, or the
use of MDL (3) module to generate the synchronization protocol.
FIRE ALARM SYSTEM CONSIDERATIONS
The National Fire Alarm and Signaling Code, NFPA 72, requires that all au-
dible notification appliances, used for building evacuation installed after July
1, 1996, produce temporal coded signals. Signals other than those used for
evacuation purposes do not have to produce the temporal coded signal. Triga
recommends spacing notification appliances in compliance with NFPA 72.
SYSTEM DESIGN
The system designer must make sure that the total current draw by the devices
on the loop does not exceed the current capability of the panel supply, and
that the last device on the circuit is operated within its rated voltage. The cur-
rent draw information for making these calculations can be found in the tables
within the manual.
When calculating the voltage available to the last device, it is necessary to
consider the voltage due to the resistance of the wire. The thicker the wire, the
smaller the voltage drop. Wire resistance tables can be obtained from electri-
cal handbooks. Note that if Class A wiring is installed, the wire length may
be up to twice as long as it would be for circuits that are not fault tolerant.
The total number of strobes on a single NAC must not exceed 69 for 24 volt
applications.
AVAILABLE TONES
The product line offers a wide variety of horn and chime tones for your life
safety needs, including temporal 3 pattern (½second on, ½second off, ½sec-
ond on, ½second off, ½second on, 1½off and repeat) which is specified by
ANSI and NFPA 72 for standard emergency evacuation signaling.
Both the horn and chime are compatible with coded power supplies. Coded
power supplies power the NAC and all connected AV devices with certain
power pattern that can be programmed from such power supplies. In this
mode there is no delay in device operations after the power is applied, the
sound will stop after the power is removed.

TAMPER SCREW
For tamper resistance, the standard captive screw may be replaced with a Torx
screw, ordered separately.
1. To remove the captive screw, back out the screw and apply pressure to the
back of the screw until it disengages from the housing. Replace with Torx
screw. (See Figure 5.)

INSTALLING A SURFACE MOUNT BACK BOX
1. The surface mount back box may be secured directly to the wall or ceiling.
Use of grounding bracket with ground screw is optional. (See Figures 6 and 7.)
2. The wall mount box must be mounted with the up arrow pointing up. (See
Figure 8.)
3. Threaded knockout holes are provided for the sides of the box for ¾ inch
and ½ inch conduit adapter. Knockout holes in the back of the box can be
used for ¾ inch and ½ inch rear entry.
4. To remove the ¾ inch knockout, place the blade of a flat-head screwdriver
along the outer edge and work your way around the knockout as you strike
the screwdriver. (See Figure 9.)
NOTE: Use caution not to strike the knockout near the top edge of the
surface mount back box.
5. V500 and V700 raceway knockouts are also provided. Use V500 for low
profile applications and V700 for high profile applications.
6. To remove the knockout, turn pliers up. (See Figure 10.)

WIRING AND MOUNTING
All wiring must be installed in compliance with the National Electric Code
and the local codes as well as the authority having jurisdiction. Wiring must
not be of such length or wire size which would cause the notification appli-
ance to operate outside of its published specifications. Improper connections
can prevent the system from alerting occupants in the event of an emergency.
Wire sizes up to 12 AWG (2.5 mm²) may be used with the mounting plate. The
mounting plate ships with the terminals set for 12 AWG wiring.
Make wire connections by stripping about
3
/
8
" of insulation from the end of
the wire. Then slide the bare end of the wire under the appropriate clamping
plate and tighten the clamping plate screw.
We provide a wire strip guide. See Figure 2 for wiring terminals and strip
guide reference.
CAUTION
Factory finish should not be altered: Do not paint!
CAUTION
Do not over tighten mounting plate screws; this may cause mounting plate
to flex.
SHORTING SPRING FEATURE
These notification appliances come with a shorting spring that is provided be-
tween terminals 2 and 3 of the mounting plate to enable system continuity
checks after the system has been wired, but prior to installation of the final
product. (See Figure 2.) This spring will automatically disengage when the
product is installed, to enable supervision of the final system.

MOUNTING AND REMOVING APPLIANCE
1. Attach mounting plate to junction box. (See Figures 3 and 4.)
2. Connect field wiring according to terminal designations. (See Figure 2.)
3. If the product is not to be installed at this point, use the protective dust
cover to prevent contamination of the wiring terminals on the mounting plate.
4. To attach product to mounting plate:
a. Remove the protective dust cover.
b. Hook the tabs on the top of the product housing into the grooves on
mounting plate.
c. Pivot the product into position to engage the terminals on the mounting
plate. Make sure that the tabs on the back of the product housing fully
engage with the mounting plate.
d. Hold product in place with one hand, and secure product by tightening the
single mounting screw in the front of the product housing.

FCC STATEMENT
These Strobes and Horn/Strobes have been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide rea-
sonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to
radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
The horn or chime will not work without power. The horn and
chime gets its power from the fire/security panel monitoring the
alarm system. If power is cut off for any reason, the notification
appliance will not provide the desired audio warning. The horn
or chime may not be heard. The loudness of the horn or chime
meets (or exceeds) current Underwriters Laboratories’ standards.
However, the horn or chime may not alert a sound sleeper or one
who has recently used drugs or has been drinking alcoholic bev-
erages. The horn or chime may not be heard if it is placed on a
different floor from the person in hazard or if placed too far away
to be heard over the ambient noise such as traffic, air condition-
ers, machinery or music appliances that may prevent alert persons
from hearing the alarm. The horn or chime may not be heard by
persons who are hearing impaired.
