2.1 VIGIL3 MODULE CONNECTIONS
The VIGIL3 Voice Alarm system is completely modular in nature.
Audio Input and Output modules are connected together in a
large Ethernet based loop (no switches required) to form a single
Voice Alarm Control and Indicating (VACIE) system.
Amplifiers are connected to the Audio Outputs of the BV3AOM8
via CA
T5 patch leads and audio inputs are connected to BV3AIM2
or BV3AIM4 modules.
BV3AOM8 modules are mounted within amplifier main frames
so the f
ault indications are visible from the front and BV3AIM2/
4 modules are mounted on DIN Rail at the rear of the rack for
easy site wiring termination.
NOTE: BV3AOM8 amd BVMBC modules do not need to be located within
the cooling air flow and can be mounted in seperate mainframes to the
amplifiers if required.
CAN Bus Modules (BVRDCI, BVRDACO, BV3MDP10F etc.)
are connected in a daisy chain configuration to a BV3AOM8.
NOTE: Speaker line monitoring CAN bus modules (BVRDACO,
BVRDNCO etc) must be connected to the BV3AOM8 serving those speaker
circuits.
