How do I integrate digital signage with my emergency comms?

You integrate digital signage with emergency comms by giving the signage CMS a priority-override capability that takes a trigger from your voice alarm system, fire panel, manual call point or mass-notification gateway, then pushes a pre-recorded full-screen message to every screen in the building within seconds. Done properly, the signage estate becomes a visible second channel alongside audio evacuation, which matters in noisy spaces, for hearing-impaired occupants and where the procedure isn't a simple evacuation.

The CMS layer is the load-bearing component. Samsung MagicInfo, BrightSign Network, Visix and Spectrio all support priority override out of the box. The override is triggered by a contact closure, REST API call, SNMP trap or SIP message from one of: a BS 5839-8 voice alarm system, the building fire panel, a manual call point on the security desk, or a dedicated mass-notification gateway like Singlewire InformaCast or AtHoc. The signage CMS holds a library of pre-recorded messages, ideally one per language and per procedure, and the trigger selects which message goes live and on which screens.

Compatibility with Martyn's Law is the framing question for UK qualifying premises. The legislation expects four documented procedures: evacuation, invacuation (move people inside, away from exterior threat), lockdown (secure in place) and communication (how you tell people what to do). Digital signage is one of the strongest "communication" channels because it works for occupants who don't have the staff app, can't hear the announcement, or weren't expecting one. The procedures themselves carry different messages: an evacuation message points to the nearest fire route; a lockdown message tells people to shelter, lock doors and stay silent; an invacuation message tells external occupants to come inside.

What "good" looks like in a real deployment: priority override across every screen within five seconds of trigger, pre-recorded messages by language and procedure, optional integration with access control (so the same trigger that locks down the building also pushes the lockdown message), and a tested fail-safe that defaults to a static evacuation graphic if the CMS itself is offline at trigger time. Build it as part of the wider security stack, not as a signage afterthought.

Quick reference: signage CMS with priority override (MagicInfo, BrightSign Network, Visix, Spectrio) + trigger from voice alarm / fire panel / mass-notification gateway + pre-recorded messages by language and procedure (evacuation, invacuation, lockdown, communication); override active across every screen within seconds.
