Description
VIGIL EVAS voice evacuation systems provide the solution for many projects, regardless of size, layout or type. The CANBUS modules, which contribute to this flexibility, are listed below.
BVRDACO:
- Amplifier/line monitor.
- 10 x BEL1 line surveillance with earth leakage fault detection.
- 11 x amplifier surveillance (10 with automatic amplifier changeover).
- 1 x RS485 half-duplex port for communicating to control microphones, fire detection systems, network control fault reporting.
BVRDNCO:
- As BVRDACO without auto-changeover.
BVRDCI:
- 1 6 x analogue voltage sensing inputs for monitored and unmonitored input access, ambient noise sensors, remote volume controls, etc.
- 4 x volt free changeover relay contacts for busy, etc.
- 8 x NPN open collector outputs 40V @ 100mA.
- 1 x RS485 half-duplex port for communicating to control microphones, fire detection systems, network control, fault reporting.
BVRDFPI:
- Fire panel interface.
- 24 x opto-coupled inputs from fire detection system.
- 1 x common fault volt-free changeover relay contacts.
- 1 x RS485 half-duplex port for communicating to control microphones, fire detection systems, network control, fault reporting.
BVRDADC:
- DC line monitor.
BVRDADIM & BVRDADIS:
- Enables dual loudspeaker circuits to connect to a single amplifier.
- Each BVRDADIS unit provides both A&B circuits for two amplifiers.
- Up to 10 spurs per loudspeaker line.
- The BVRDADIM master unit connects to the BVRD2M router.
- Up to five BVRDADIS can be connected to one BVRDADIM.
- Fitting five BVRDADIS enables broadcast and monitoring for up to twenty loudspeaker circuits. (The modules plug directly together.)
- Utilises DC line monitoring techniques, therefore BEL1 end of line monitoring is not required. (Please refer to ‘system requirements’.)
- Failure of either the A or B circuit from one amplifier will not effect the other circuit.
- In the event of an amplifier failure, reserve amplifiers will automatically operate.
- With five BVRDADIS fitted, a one-in-ten amplifier changeover ratio is enabled.
- Earth leakage protection.
