Control Unit Location
The information in this section provides the user with guidelines necessary for
installation.
Consider the Control Unit mounting location. Mount the Control Unit NEMA Type 1
cabinet indoors and away from moisture, heavy dust, and contaminants. The controller
contains batteries; therefore, the selected area must have adequate ventilation to prevent
accumulation of explosive gas from the batteries.
A light duty lockable hasp secures entry to the cabinet.
The cabinet is suitable for wall mounting with mounting slots on 12 to 16 inches centers.
The total weight of the control assembly, including user-provided batteries, are listed
in the specification section. Ensure that the mounting surface and fasteners can safely
sustain the weight of the assembly.
The control system requires a 120 Vac or 240 Vac, 50 to 60 Hz power source (model
dependent).
You can use several methods to activate the UVIC system. Use the manual activation
switches and a handheld microphone to activate the system locally. Use landline control
through normally open contact switches. Make connections directly to the backplane
motherboard terminal block. The system can be remotely activated through a radio
transceiver or an external 600-ohm audio source.
If you are using radio control, consider RF coverage and antenna placement when
selecting a suitable location.
