Addressable systems work on a 2 wire loop system, each of the devices has an address and can reply back to the control panel giving its address and status. The control panel then analyses the data to establish the status of the device and can report devices as being normal, fault, pre-alarm and fire.
The base sounder and sounder with visual indicator are addressable loop powered devices use on ZP fire alarm systems.
The ZP755B-2P combines a detector base and audible sounder in a single stylish moulding.
The ZP755BV-4P also combines a detector base, audible sounder and includes a high intensity visual indicator in a single stylish moulding. It offers both audible and visual warnings from a single, addressable, loop wired unit.
These devices provide an elegant solution for areas where the installation of a separate detector and sounder would prove expensive, both in equipment capital value and system wiring costs.
