LED L-series Indoor Horn Strobes and Strobes — P/N I56-0022-000 8/25/2023 7
Section 3: Installation
3.1 Wiring and Mounting
All wiring must be installed in compliance with the National Electric Code (UL applications), (Canadian Electric Code (ULC applications),
and local codes as well as the authority having jurisdiction. Wiring must not be of such length or wire size which would cause the notifica-
tion appliance 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 field
wiring.
Make wire connections by stripping about
3
/
8
" of insulation from the end of the field 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 6 for wiring terminals and strip guide reference.
3.2 Wiring Diagrams
The 2-wire horn strobe and strobe only require two wires for power and supervision. (See Figure 7.)
Shorting Spring Feature. These appliances enable system continuity checks of field wiring on the mounting plate before appliances are
installed. The mounting plate has a shorting spring between terminals 2 and 3 that will automatically disengage when the product is installed,
to enable supervision of the final system. (See Figure 6.)

– Note for positioning: Ceiling mount back boxes: Ceiling surface mount back box SBBCR/WL is a common back box for ceiling
horn strobes, strobes, speakers, and speaker strobes. Use the top (SPK) mounting holes for ceiling speaker and speaker strobe
products. Use the bottom (STR) mounting holes for ceiling horn strobe and strobe installation needs.. (See Figure 15.)
2. Select appropriate knockouts and open as needed.
– 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.
– If using the ¾ inch knockout: 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 17a.)
NOTE: Use caution not to strike the knockout near the top edge of the surface mount back box.
– V500 and V700 raceway knockouts are also provided. Use V500 for low profile applications and V700 for high profile applications.
To remove the knockout, turn pliers up. (See Figure 17b.)
