Fire Safety Integration
EN 54 certified fire alarm panel integration with KNX via dry-contact relay, smoke detector wiring for 2-wire and 4-wire loops, and fire door control with electromagnetic door holders and BS 5839 / EN 54-2 compliance.
Fire alarm panel integration with KNX: EN 54, dry contacts and relay logic
How to correctly interface a certified fire alarm panel with a KNX building automation system using volt-free dry-contact relay outputs, galvanic isolation, KNX binary input modules and safety-priority group addresses — covering EN 54-2 required outputs, cause-and-effect matrix, cable requirements and BS 5839-1 vs EN 54-2 comparison.
Smoke detector wiring: 2-wire and 4-wire loop configurations
Complete wiring guide for conventional 2-wire zone loops and addressable 4-wire loops — end-of-line resistor calculations, Hochiki ESP and Notifier FlashScan addressing, Class A vs Class B loops, EN 54-7 detector spacing rules, cable specification to BS 5839-7 and false alarm management for analogue-addressable panels.
Fire door holders and electromagnetic door release: EN 1155 and KNX control
EN 1155 electromagnetic door holder specification, fail-safe 24V DC wiring from EN 54-4 certified power supplies, release method hierarchy (fire panel primary, KNX secondary), acoustic door holders for retrofit, daily time-switch management via KNX, and the common mistakes that fail fire safety inspections.
Fire-safe panel design for EN 54 projects
We design and build panels for fire-integrated KNX installations — including certified relay interfaces, fire-rated cable termination, galvanic isolation and cause-and-effect logic pre-tested before delivery.
