• UVARM has the ability to send line level audio output to external equipment such as
fire alarm panels or amplifiers, and relays for activation of strobes or LEDs.
• Power control ramps up siren or speaker volume for added safety, custom volume
settings, and low power testing.
UV Controller Overview
The UV controller consists of two cabinets, which are bolted to a mounting channel for
ease of shipping and installation. The Control Cabinet (NEMA 4X) houses a card cage for
easy installation and maintenance of plug-in cards. The card cage has a capacity of ten
cards consisting as follows:
• One controller position (UV+)
• One accessory position for optional audio and relay module card (UVARM)
• Eight amplifier positions (UV400)
Each UV400 amplifier provides 400 watts to drive any combination of speaker drivers up
to 400 watts. Depending on the number of amplifier cards installed, eight power levels
are available from 400 watts to 3200 watts.
Activation codes, command sequences, and operating parameters are uploaded from a
computer through the RS232 port located on the front panel or over a communication
channel with the Federal Signal Commander software. All information is stored in non-
volatile memory that is immune to power and battery loss.
The control board, amplifiers, and optional equipment are all modularly constructed for
easy removal. In most instances, field service is limited to replacing a slide-out module,
which a non-technical person can perform with only a screwdriver.
The Battery Cabinet (NEMA 3R), the lower cabinet, houses rechargeable batteries. The
cabinet houses two or four batteries depending on the number of amplifiers used and
based on battery backup runtime and standby time. The lower and upper cabinets are
interconnected by a conduit, which is sealed to prevent any harmful gases from entering
the Control Cabinet. The AC charger or solar (regulator) maintains the charging of the
batteries. The batteries provide power to the Control Cabinet. The batteries continue
providing power to the Control Cabinet in the event of an AC power failure; typically, the
standby minimum is seven days.
The UV400 amplifiers are ordered separately, and quantity is based on the type of
speaker array. Refer to the following tables to determine the quantity of amplifiers to order
various siren combinations.
