Lockdown · Evacuation · Medical · Panic. Announced over your existing PA. Every phone on staff told instantly, even on silent.
Emergency & Lockdown System turns one iPad plugged into your PA amplifier into a complete emergency alert station. Staff carry the free Emergency Remote on their own iPhone or Android: hold a button and the site hears the alarm, the office sees who raised it and where, and every registered phone gets a critical alert that cuts through silent mode. Raise it silently when sound would make things worse. No cloud, no server, no wiring beyond one audio lead.
How the station connects to your PA, registering staff phones, raising a lockdown from a phone, the silent alarm, live location, and the All Clear.

Two apps that find each other on the site Wi-Fi. The iPad lives with the PA amplifier and does the announcing; staff phones are the triggers. Everything below is standard — nothing is an add-on.
Lockdown, Evacuation, Medical Emergency and Panic. Press and hold for 1.5 seconds so nothing fires by accident; the phone confirms "Received by station". The PA plays the siren pattern and a clear spoken announcement, twice, then repeats until All Clear.
Tap Silent Mode and the alarm makes no sound over the PA. The office and every registered phone are told quietly. Escalate to the full PA alarm later with one hold, once it is safe to make noise.
Emergency Remote uses Apple Critical Alerts on iPhone and Do Not Disturb override on Android, so a silenced phone in a drawer still sounds. Phones get a normal alert tone; the siren only ever plays over the PA.
The PA announces who raised the alert. Their GPS position goes with it and shows on a map on the station and every phone. On the alarm screen they can type where they are — "on the oval, west end" — and the PA re-announces it.
Admins send notices to every staff phone with a normal tone (wet-weather timetable, assembly moved), and make PA announcements from their phone — typed for the announcer voice, or recorded in their own voice and saved to a shared library.
Each phone registers with its own ID and security token and waits for the office to approve it. Star the admins, remove a phone in one tap. Every alarm, update and All Clear is logged with who and when, exportable as a CSV for your records.
Designed around what a teacher actually does with a phone in a frightening moment: one hold, no typing, no menus.
Alerts tab, hold Lockdown for 1.5 seconds. Silent Mode first if sound would make things worse. The phone confirms it was received.
The station plays the siren pattern and the spoken announcement over the school PA — "Lockdown. Lockdown. This is not a drill. Raised by Sam Taylor." Then repeats until stood down.
Every registered phone gets a critical alert with who raised it and where, a live map, the Call 000 button, and — in a lockdown — an "I'm hiding" button that silences that phone and tells the office they are hiding.
Anyone can add an update or their location; lockdown updates go to phones only, never the PA. The office or an admin holds All Clear and the PA gives the spoken stand-down.
The Emergency Station sits on the PA and keeps listening in the background, even while a bell scheduler or another app owns the screen. When an alarm comes in it takes over the display with everything the office needs.








Finds the station on the site Wi-Fi, registers once with a name and role, and reconnects itself from then on. Staff see calm status day to day; the alarm screen only appears when it matters.








Every decision in the app follows one rule: never make a bad situation worse, and never leave the office guessing.
A teacher who sees a threat can raise the alarm silently, so no siren gives away that the alert has gone out. When it is safe, anyone can escalate it to the full PA lockdown with one hold.
During a lockdown, updates and locations go to staff phones and the office only. Nothing is broadcast that could tell an intruder where people are.
One tap puts that phone into a no-sound, no-vibration state until All Clear, and tells the office that person is hiding. Only Lockdown and Panic show it; Medical and Evacuation don't need it.
A lesser alarm can't replace an active lockdown. The phone that raised it is told it was logged but not announced. Nothing silently disappears.
The alarm screen carries a one-tap Call button for your country's emergency number: 000, 911, 999, 112 or 111, set once on the station and sent to every phone.
Switch on Drill Mode and every announcement is prefixed "This is a drill", phones show a drill badge, and history is flagged. Everything else runs exactly as it would for real.
The station is just another audio source to your amplifier: it plugs into the line input like a CD player did. Already running a bell scheduler on an iPad? The station runs in the background on the same iPad.
One 3.5 mm aux lead to the amplifier's line input. The charging port stays free for the wall charger.
Add a USB-C to 3.5 mm audio adapter with charging pass-through (about $20) so the iPad charges 24/7 through the same port.
Install the station on the same iPad. It keeps listening in the background while the bell app runs in front, and takes the PA when an alarm comes in.
Any iPhone on iOS 16 or newer, any Android phone on Android 8 or newer, on the site Wi-Fi. Free, no accounts.
The system is complete and in final testing with schools now. One station licence covers the whole site; the staff app is free for every phone. Pilot sites get direct support from the developer during rollout.
Yes. The station and the phones talk directly over the site Wi-Fi. Alarms, announcements, updates and All Clear all work with no internet. Only the push-notification path for phones that have wandered off the Wi-Fi uses the internet.
Yes. Emergency Remote is approved by Apple for Critical Alerts on iPhone, and uses Do Not Disturb override on Android. A phone in a drawer on silent still sounds. The siren itself only ever plays over the PA — a phone gives a normal alert tone.
Yes. Tap Silent Mode, then hold the alarm. Nothing plays over the PA; the office and every registered phone are told quietly. It can be escalated to the full PA alarm with one hold when it's safe.
Panic uses coded wording over the PA so staff know exactly what's happening without alarming students. The wording of every announcement — and the sound for every alarm — can be changed on the station.
No. Every phone registers with its own ID and security token and waits in the Devices list until the office approves it. Removed phones can't re-enrol themselves. The station's Settings and All Clear can be PIN-protected.
No. Admins (starred phones) can send All Clear, staff notices and PA announcements from wherever they are on site. The iPad can live in the comms rack.
No. The iPad is the server. There are no accounts, nothing is stored off-site, and no data is collected. See the privacy policy.
No. The station runs in the background on the same iPad and takes over the PA when an alarm comes in.
Pilot sites are being onboarded now. We'll set it up with you and run the first drill together.
