AVAC is a new low-cost, high-quality modular voice alarm system designed to simplify the provision of a BS5839 part 8 compliant voice alarm system. The fact that multiple AVACs (and slaves) can be  onnected to a fire detection system makes AVAC ideal not just for simple one zone installations but for virtually all small to medium sized applications, including phased evacuation projects.With high quality pre-recorded digital messages, near CD-quality sound and ancillary connections for optional emergency microphones, public address and background music equipment, AVAC is particularly suited for factories, office blocks, shopping centers, hotels and leisure centers.AVAC is suitable for category V1 and V2 systems complying with BS5839-8 (2008).
In one compact wall-mountable enclosure, the AVAC comprises:-
Standard Features
- A Context Plus XP95 specific interface for direct connection to a Context Plus fire alarm loop
- A straightforward fire alarm interface that can be connected to any analogue addressable fire alarm system via a series of input/output units on the loop
- A high-quality digital message store containing programmable Evacuate, Alert and Test messages
- A prioritized mixer
- Two x 60-Watt continuous average power Class D amplifiers (plus an optional standby amplifier)
- An EN54-4 compliant switch mode power supply and battery charger
- Three balanced line level inputs for the (optional) connection of an emergency microphone, paging/public address microphone(s) and a background music source
- Space for 2 x 7Ah VRLA batteries typically providing at least 24 hours standby and 30 minutes alarm running time
- A slave line level output allowing the connection of up to 26 slave AVAC amplifiers to extend loudspeaker coverage and allow greater flexibility over public address paging and background music distribution (as they have their own paging and background music inputs)
