Baldwin Boxall – Voice Alarm Monitoring Options
Our voice alarm monitoring products are BS EN 54 certified
All critical signal paths of a voice alarm/VACIE system must be fully monitored – from the fire officer’s microphone, through the amplifiers to the end of the loudspeaker lines. Also, any faults detected with the power supply, internal battery charger and backup batteries must be reported and acted upon.
Monitoring products available:
DC LINE MONITOR ISOLATOR:
- CANBUS modules consisting of two components: BV3ADIM and BV3ADIS.
- The BV3ADIM master unit is capable of controlling up to five BV3ADIS units
- Enables dual loudspeaker circuits to connect to a single amplifier
- Each BV3ADIS provides both A&B circuits for two amplifiers
- Up to 10 spurs per loudspeaker line
- DC line monitoring
BVRDADC – DC LINE MONITOR:
- DIN rail mounted CANBUS module with screw terminals for connections to amplifiers and loudspeaker lines
- 11 x amplifier surveillance (10 with automatic amplifier changeover)
- Monitors the integrity of loudspeaker lines by measuring a small DC current
BVLAM – IMPEDANCE MONITOR:
- Rack mountable unit – 1U high, two units fit across one rack ‘shelf’
- Enables eight loudspeaker zone selection from one amplifier
- Provides constant impedance monitoring on each of the eight loudspeaker circuits selected. (NB: due to detection accuracy, BVLAM is only suitable for VA systems with less than five speakers per circuit.)
BEL1 – END OF LINE:
- An active unit which is installed on each loudspeaker circuit
- Dimensions: 80mm H x 40mm D x 140mm W
- RAL 7046 finish
BEL1IP – END OF LINE:
- Weatherproof version of the BEL1.
- 97mm H x 80mm D x 157mm W
- Grey plastic finish.
BEL10 – END OF LINE:
- DIN rail mounted, the BEL10 is the equivalent of ten BEL1 units
- Typically, the BEL10 is used to ease the upgrading of an existing voice evacuation system, where loudspeaker lines are wired in a loop back to the rack
BVRDACO – AMPLIFIER/LINE MONITOR:
- DIN rail mounted CANBUS module
- 10 x BEL1 line surveillance with earth leakage fault detection
- 11 x amplifier surveillance (10 with automatic amplifier changeover)
BVRDNCO – AMPLIFIER/LINE MONITOR:
- As BVRDACO without auto-changeover
