Haydon HAY-FIRE-ISO Fire Alarm Mains Isolation Switch

The Haydon HAY-FIRE-ISO is a purpose-designed fire alarm mains isolation switch developed to provide safe and controlled isolation of mains power supplies feeding fire alarm control panels, detection systems, and associated life safety equipment. Designed for use by authorised personnel, the unit incorporates a key-operated switch mechanism that prevents unauthorised disconnection of critical fire alarm systems.

Featuring a double-pole switching arrangement, the HAY-FIRE-ISO isolates both live and neutral conductors, ensuring maximum safety during maintenance, commissioning, fault finding, and servicing operations. The integrated F4A fuse provides circuit protection, while the switch design disconnects the fuse from the supply when switched off.

A mains neon indicator clearly displays the presence of power at the switched output, allowing engineers and maintenance personnel to verify system status at a glance. The distinctive red enclosure ensures easy identification in accordance with fire alarm installation practices and industry standards.

Manufactured to support installations working in accordance with BS 5839-1, the HAY-FIRE-ISO is suitable for commercial, industrial, educational, healthcare and public-sector fire alarm systems where safe mains isolation is required.
