Wihkum is a staff duress alarm app for schools. Staff press HELP on their own iPhone or Android phone, and the people your school has set for that help type, such as the closest trained staff, are alerted with their location inside the school’s geofence. Master users can trigger a lockdown or evacuation, every incident is recorded, setup can take as little as 2 hours, and pricing starts at A$3 per user per month.

Teachers and support staff shouldn’t have to send a student running to the office with a coloured card when something goes wrong. Wihkum is a duress alarm system for school staff that turns each staff member’s own phone into a personal duress alarm. It’s set up around your school’s grounds, so when someone presses HELP, the right people know who needs help and where. Staff download the free app, and your school can be up and running in as little as 2 hours. Pricing starts from A$3 per user per month.

How the Wihkum duress alarm works

When a staff member presses HELP, Wihkum alerts the people your school has chosen for that type of help, not the whole school, so help can get there quickly without unsettling everyone else.

  1. Your school sets a geofence. This is a virtual boundary drawn around your school grounds. Learn more about how school geofencing works.
  2. Staff download the free app on their own iPhone or Android phone.
  3. A staff member presses HELP. GPS pinpoints where they are on the grounds.
  4. The right people are notified, with the person’s location. Who is notified depends on the help type your school has set up. For example, students fighting in the playground can notify the closest trained staff, while an intruder alert can call emergency services and notify staff. The alert sounds even if a phone is on silent or Do Not Disturb.
  5. Everyone can see who’s coming. A real-time view shows which responders are “On the Way”.

Help types for every school situation

One duress button covers everything from a student’s allergic reaction to an intruder on the grounds. When staff press HELP, they can choose the type of help they need, so responders know what to expect before they arrive:

  • Medical, such as a severe allergic reaction or a seizure
  • Accident, such as fractures, cuts or head injuries from play equipment
  • Behaviour
  • Harassment and bullying
  • Mental health, including staff anxiety and burnout
  • Intruder or active shooter
  • Fire, structural damage or chemical spill

Each help type can be set to notify different people. For example, an intruder alert can call emergency services and notify staff, while students fighting in the playground can notify the closest trained staff. Your school can also create its own help types, each with its own alert tone, to suit the way your school works.

Lockdown and evacuate from the same app

Some situations need the whole school to act at once. In Wihkum, nominated Master users can send an immediate lockdown or evacuate notification to every staff member. Only Master staff can see and use these two buttons, so everyday staff accounts stay simple and focused on calling for help. For more on planning ahead, see our guide to school lockdown systems.

No accidental lockdowns: how Wihkum prevents false alarms

In the United States, some schools give staff wearable panic badges, and some of those badges have started full lockdowns by mistake:

  • Molalla High School, Oregon (22 September 2026): a staff member asking for help accidentally set off their panic button and started a lockdown. Police were already on campus before it was cleared. At a board meeting on 8 October 2026, the district said it would pilot sending alerts to administrators first, so they can review them before a full lockdown. Sources: Molalla High live feed, Citizen Portal, 8 October 2026.
  • West Laurens High School, Georgia (16 September 2026): a staff badge pressed against something inside a small bag set off an alarm, and the school went into a brief lockdown. Source: The Courier Herald, 16 September 2026.
  • Florida (2024–25 school year): of more than 54,000 alerts from a statewide wearable panic button system, 44% related to student behaviour, about 1% to a campus threat and about 1% to suspicious activity. Most of the rest were drills (23%) and system tests (13%). Source: WLRN, 2 April 2026.

Most calls for help are everyday medical or behaviour situations. A false lockdown frightens students, brings in police and can make people take real alerts less seriously.

In Wihkum, a call for HELP and a whole-school lockdown are kept separate. HELP alerts the closest trained staff. Only Master users can start a lockdown or evacuation, and they must enter a one-time 4-digit code first. That means a bumped phone, a press in a pocket or a wrong tap can’t put the school into lockdown on its own.

The right help for everyday incidents, and a deliberate, confirmed step for a lockdown.

Privacy and location: what staff need to know

Nobody can see where you are unless you press HELP. Then, and only then, trained responders see your location. The app checks location periodically so it can work out who the closest responders are, but that information isn’t visible to anyone until help is requested.

Wihkum doesn’t sell data to third parties. Its only income is subscriptions. The app is also light on your phone, using about 3% to 8% of battery a day, depending on movement, and about 3 to 5 MB of data a month. Read more about security and privacy.

Set up in as little as 2 hours

Upload your staff list in bulk and Wihkum can be running across your school in as little as 2 hours. The app works on any phone currently supported by Apple or Android, so there’s no extra hardware to install. Custom schedules let you set when the system runs during school hours, weekends and holidays, and support staff such as gardeners and cleaners can call for help 24/7. Schools in Western Australia can also read about emergency help for schools in WA.

Pricing: from A$3 per user per month

Wihkum starts at A$3 per user per month. Pricing depends on your school, so tell us how many staff you have and a Wihkum representative will be in touch to discuss pricing for your school.

Duress alarms and your WHS duty of care

Under model WHS laws in Australia, organisations must manage the health and safety risks of workplace violence and aggression. In the US, the OSH Act 1970 requires employers to provide a safe workplace, and in the UK the Health and Safety at Work Act 1974 does the same.

Wihkum doesn’t replace your risk assessment, but it helps you meet your duty of care in practical ways. It gives staff a fast way to call for help and identifies trained responders in advance. It also records every incident, including the date, time, staff involved and location, so you can report on it and review it.

Wihkum vs wearable and fixed duress buttons

A fixed duress button only works if you’re standing next to it. Wihkum goes wherever your staff go on the school grounds, on the phone they already carry.

Duress alarm FAQs

How does a duress alarm work in a school?

Staff press HELP on the Wihkum app, and the people your school has set for that help type, such as the closest trained staff, get an alert with their location.
