Addressable systems work on a 2 wire loop system, each of the devices has an address. The control panel monitors these devices and analyses the data they send in to establish the status of the device. The panel then can report devices as being normal, fault, pre-alarm and fire.
The ControlMaster ZP2 is available as 1 loop with up to 64 zones with 300 output groups or 2 loops expandable to 4 with up to 256 zones with 300 output groups, both with fire brigade and fire protection controls.
The small cabinet has up to 24 LED Zone indicators for fire and fault with space for a 4 digit number, the larger cabinet has up to 40 LED Zone indicators for fire and fault with ample text space.
