The Haes Comms Card (TPCA05) enables networking of up to eight XLEN or XL32 control panels. Panels can be combined in any configuration, ranging from 2-zone to 32-zone units, in any order, to provide a total of up to 256 conventional or Twin Wire zones. The card is a simple plug-on module that mounts directly onto the main control panel circuit board.
In addition to the eight control panels, the network can support up to eight repeater panels or remote display units. These remote displays are supplied with a 4 × 40 character backlit LCD and provide full system status, showing all fire and fault conditions, as well as allowing global control of functions such as Silence and Reset across the entire network.
The networking system is designed for fault-tolerant (fail-safe) loop wiring, connecting from Comms A to Comms B and returning to the main panel. Where existing installations cannot accommodate a loop configuration, such as when upgrading older systems, the master panel can be reprogrammed to legacy RS485 communications monitoring. This allows virtually any cabling topology to be used.
Each card also includes six programmable switched negative outputs, which can be used to meet local switching or interfacing requirements.
