ESP MAGfire Auxiliary Isolation Switches
The ESP MAGfire Auxiliary Isolation Switches range provides robust key-operated devices designed to safely isolate mains and auxiliary circuit supplies in conventional fire alarm systems. These switches help installers and maintenance teams work on fire panels and ancillary equipment without the risk of live voltage, improving on-site safety and compliance. ESP MAGfire auxiliary isolators — such as MAGAUXISORP (red) and MAGAUXISOWP (white) — are engineered to handle mains switching up to 8 A, making them suitable for isolating typical fire alarm control panel supplies or auxiliary relays. Keyed operation adds a layer of tamper-resistant security, limiting access to authorised personnel, while clear LED indicators show operational status at a glance. Mounting is straightforward with supplied surface back boxes for either flush or surface installation, and programmable features — where supported — help tailor activation behaviour to site needs. These switches are part of the wider MAGfire conventional fire alarm range, helping installers build safe, maintainable fire system circuits with confidence.
