HFP APS-CZ4

To further enhance the versatility of the HFP fire alarm system, four conventional detection circuits can be connected with up to 30 detectors per circuit. Conventional control panels can be replaced with this simple module and existing conventional systems can be interfaced directly to modern analogue addressable control systems and networks. A fail safe mode ensures that the detection inputs will still operate the sounder outputs and fire contact if communication to the HFP panel is lost. Up to 32 of these boards can be connected to the dedicated RS485 communications bus in the control panel giving the capability of up to 128 conventional zones with 64 sounder outputs. The detection zone boards may be mixed on the RS485 bus with 16 channel I/O Boards, 6 way sounder boards or 8 way relay boards to provide a very flexible system of I/O to satisfy any requirement. All inputs and outputs are configurable in the same way as devices connected to the loops and all may be acted upon by cause and effect logic. Standard HFP control panels contain fixings for one (four way) Detection Zone board, Sounder board, Relay board or I/O board, all of which can easily be connected using four signal wires to the power and comms bus within the panel. Consideration must be taken as to the loading on the main panel.
