Installation
Electrocution or severe personal injury can occur when making electrical
connections, drilling holes, or lifting equipment. Therefore, experienced electricians
in accordance with national and local electrical codes, acting under the direction of
the installation crew safety foreman, should perform installation.
Explosive gases and corrosive materials may be present. To prevent explosion or
severe personal injury, installation technicians must be experienced with the safe
installation of lead-acid type batteries.
Recommendations on Control and Battery Box Location
First consider the siren location and method of activation before determining control
and battery box location. You can activate the DCFCB and DCFCTB unit remotely
through radio or landline controls and locally using pushbuttons provided in the
control unit. Refer to the Land Line Control section on page 60 for additional
information on remote activation using landline controls.
Since the controls are in a NEMA 4 rated enclosure and the batteries are protected,
you may install the controls indoors or outdoors. If you install indoors, ensure
adequate ventilation is provided for the four lead acid batteries to prevent build-up of
explosive gas.
To ensure proper siren power is maintained, it is recommended that the control and
battery box location be within a 50 feet wire run to the siren. If it is necessary to
make a longer run, use a 1 AWG or larger wire for the siren motor.
When mounting the control and battery box, it is recommended that the units be out
of reach to avoid vandalism but accessible to service personnel. Both boxes come
equipped with padlock hasps. Use these for added security.
The control and battery boxes are shipped mounted on an aluminum channel with
four mounting holes for 1/2-inch bolts. The total weight of the control and battery
box is approximately 364 pounds including the batteries. Therefore, insure that the
mounting surface and fasteners can safely sustain the weight of the assembly and any
additional environmental stresses placed on it.

Note: When installing this product, insure that Local and NEC guidelines are
followed.
