Cause-and-Effect Matrix.
Also known as · C&E matrix · Cause-effect register
Written, signed, witnessed table tying every input event (fire, nurse-call, medical-gas, access-control, CCTV, BMS) to every gated output (PA, AHU damper, lift, mag-holders, CCTV bookmark, BMS log) with acknowledgement-delay tiers.

What this connects to (outgoing edges)
Supports
Hospital ELV Stack
Clinical-occupancy ELV coordination — fire-alarm, nurse-call, medical-gas alarm, access-control, IP-CCTV and BMS converging on a cause-and-effect supervisory matrix with NABH pressure-boundary discipline and OT-anaesthesia acknowledgement-delay tiers.
Supports
High-Security ELV Stack
Coordinated perimeter screening (UVSS, ANPR, X-ray, RFID auto-recognition), control-room CCTV, EPABX-LAN backbone, per-load UPS topology, chemical-earthing strategy and hand-off boundaries to convenience features that run in parallel with screening.
