The Eaton Flexi EFBW8ZFLEXI is an 8 zone fire alarm control panel that can run each zone as either a BiWire (two-wire) or a standard conventional zone. Because every zone is configured individually, BiWire and conventional devices can be mixed on the same system, which makes the panel well suited to new installations, extensions and upgrades of existing conventional systems. It is certified to EN 54-2 and EN 54-4 and designed to meet the recommendations of BS 5839-1.
Key features
- Each of the 8 zones can be set to BiWire or conventional mode
- Connect an existing conventional system to a BiWire system
- Compatible with two-wire and conventional EN 54-23 certified visual alarm devices (VADs)
- Up to 32 detectors and manual call points per zone
- Conventional sounder circuits: none if all zones are BiWire, 2 if up to 4 zones are conventional, 4 if 5 or more zones are conventional
- Volt-free Fire, Fault and Interlink relays plus an auxiliary output
- Class change input to activate all sounders
- RS485 repeater port
- Straightforward, intuitive interface for simple programming and maintenance
