By the DC Fire & Security engineering team — installing and maintaining fire and security systems since 2010. Updated June 2026.
A panic (hold-up) alarm signals a deliberate emergency — robbery, threat, violence — silently to an ARC for priority response, without sounding on site. Options: fixed buttons at tills/receptions, wireless pendants/fobs for mobile staff, and app/lone-worker devices beyond the building. Police treat confirmed hold-up activations as priority; false activations are policed hard. Cost: £150–£500 added to a monitored system.
Hold-up alarms ride the same NPCC framework as intruder URNs but with sharper handling: HUA activations are treated as crime-in-progress priority, callbacks to premises are avoided (an aggressor answering changes nothing good), and false activations burn response fast — typically two false HUAs in twelve months triggers withdrawal, stricter than intruder strikes. Hence the design emphasis on deliberate-action devices (dual-press, shrouded buttons), staff training ('this button is a police car, not a manager call'), and test procedures agreed with the ARC. Certificated installation and maintenance are scheme requirements as with any URN path.
The clear cases: cash-handling retail (convenience, betting, pharmacy, jewellers — where insurers often require HUA provision), licensed premises at closing, GP/dental/housing receptions facing public aggression, schools' front offices, and any lone-opening/closing routine. Adding HUA to an existing monitored Grade 2/3 system: £150–£500 installed depending on button count and wireless needs; standalone monitored panic provision for premises without intruder systems prices like a small monitored install. Lone-worker app services run £5–£15/user/month. We fold HUA design into commercial surveys by default where the trade profile suggests it — and train staff at handover, because the button's value is the confidence to press it correctly.
We install and maintain fire and security systems across Bedfordshire, Hertfordshire and London — with fixed written quotes, a 36-month warranty, and certification your insurer will accept.
