6. Install a user-supplied, fused,
disconnect switch. Use the
proper type required by the
authority having jurisdiction in
your area.
7. If the speaker array is installed on
the roof of the building, it may be
desirable to install the control and
battery box inside the building, if
practical.
5.1 Electrical Connections
A. General
Install the siren electrical system in
compliance with local electrical codes
and NEC recommendations.
As a safety precaution to protect
personnel and equipment, ALL SIREN
UNITS MUST BE SOLIDLY
CONNECTED TO AN EARTH
GROUND. If the siren is installed on a
building, ground the system to a metallic
object known to be on a dedicated earth
ground. For pole mounted installations,
drive a metal rod or bar at least eight
feet (8 ft.) into the ground, as close as
practical to the base of the pole. FOR
MAXIMUM PROTECTION, USE A
SEPARATE, CONTINUOUS 6 AWG
OR LARGER WIRE FROM THE SIREN
FRAME TO GROUND AND FROM THE
CABINET OF EACH SIREN UNIT TO
GROUND.
NOTE: CONDUIT CONNECTIONS
MUST BE SEALED AND PROTECTED
TO PREVENT WATER ENTRY AND
CORROSION IN THE CONTROL
CABINET.

B. Power Connections
1. Route 1/2" conduit (steel
preferred) between the usersupplied,
fused disconnect switch
and the conduit-fitting hole in the
bottom right-hand of the control
unit enclosure. Use weatherproof
switches, electrical boxes and
connectors to prevent water
entry and corrosion.
2. Route two (2) user-supplied
power wires and a ground wire
through the conduit that was just
installed between the control unit
and the fuse disconnect box.
Use wires no smaller than 14
AWG. Connect the ground wire to
the green and yellow DIN
mounted terminal block or the
cabinet ground stud. Verify the
appropriate siren model has been
purchased. 240VAC models
contain a step-down transformer
pre-wired to the DIN rail located
on the right side of the control
cabinet. Connect the two AC
power wires to the DIN mounted
terminal blocks labeled L1 and
L2.
Connect the power wires and the
lightning protector to the AC
disconnect box per instructions
provided with the lightning protector
and governing electrical codes.
