Calling for help quietly

Most alarm features make noise, which is not always what you want. If someone is threatening you, a siren may make matters worse. Panic buttons and duress codes are two ways to ask for help without drawing attention. Both usually send a signal to the monitoring center while the system appears to behave normally.

These are features for emergencies, and they are not a substitute for calling emergency services directly if you can do so safely. They are best understood as an additional option that may be useful in particular situations.

Panic buttons

A panic button is a dedicated trigger for an emergency. It may be:

  • A key or button on the keypad. Many keypads have dedicated panic keys, often pressed together or held for a couple of seconds to reduce accidents.
  • A wireless pendant or key fob. These can be worn or carried and work within the range of the panel.
  • A fixed button. Businesses often install buttons under counters, desks or at reception, where an employee can press them discreetly.
  • A button in a phone app. Some systems let you send an alert from a smartphone.

Panic buttons are usually categorized by what they signal. Common types include audible and silent versions, as well as ones for fire, medical or police needs. A silent type typically notifies the monitoring center without sounding a siren. An audible type may sound the siren in addition to sending the message. Which type is appropriate depends on the situation and local rules.

Duress codes

A duress code is a special alternate disarming code. If a person is forced to turn off the system under threat, they can enter the duress code instead of the normal one. The panel disarms as if nothing is wrong, so an attacker sees the expected result, but it also sends a silent signal to the monitoring center indicating that the user is under duress.

For this to work, a few conditions apply:

  • The system must be monitored. A duress signal that goes nowhere accomplishes nothing.
  • The monitoring center must know how to treat the signal and what to do next. This should be agreed in writing.
  • The code must be different enough from the normal one to avoid accidental use, yet memorable enough to be entered under stress.
  • Responders may approach differently, which is a reason to understand local procedures.

A tip for choosing the code: many panels restrict simple patterns. Avoid something that is only one digit different from the regular code, since it is easy to press by mistake and may also be easy to guess.

When these features are appropriate

Situations where people consider these tools include:

  • A business with cash handling or a counter where staff could face a hold-up.
  • A home where someone has reason to fear a forced entry or confrontation.
  • Someone vulnerable living alone, who may need a quick way to request urgent help. This overlaps with the issues in the article on senior safety.
  • A property where a delivery or visitor could attempt to force an occupant to disarm.

They are not appropriate for casual use. A panic alert normally means a serious request for assistance, and misuse can have consequences, including fines or reduced trust from responders in some areas.

Limits and cautions

  • Response is not guaranteed or instant. Time and outcomes vary.
  • False activations happen. A bag brushing a keypad or a child pressing a button can send a real alert. Make sure everyone knows how to cancel and how to notify the monitoring center if it was a mistake.
  • A silent alert is still an alert. If the attacker notices the monitoring call-back, it may increase the risk. Ask the provider how it handles duress signals: calling the premises may not be appropriate in that case.
  • People differ. Under stress, some people forget codes. Practice, within the limits your provider allows, to build confidence.
  • Local rules vary. Some places treat panic alarms specially, with specific permits or response policies. Check with your local authority.

Planning and practicing

  1. Decide who needs access. In a workplace, that could be every employee at a counter. In a home, perhaps adults only.
  2. Choose locations. Place panic buttons where they can be reached naturally, such as near the entry door or beside the bed, and hidden from view if appropriate. Avoid positions where they can be pressed by accident.
  3. Agree on a procedure. Write down what the monitoring center will do upon receiving each signal, and who will be contacted.
  4. Brief the right people. Tell family members or staff how the features work and what not to do, such as pressing the button repeatedly or announcing it.
  5. Test with the provider. Ask the monitoring center to put the account into test mode first, so that an exercise does not trigger a real dispatch.
  6. Review periodically. Change the duress code if it becomes known, and update lists when people join or leave. See also the notes on managing employee credentials.

Where this fits in the whole system

Panic features are one part of a broader emergency plan. Working smoke detectors, a method for contacting emergency services, and a plan for where to go in an emergency all matter more than any single device. Treat panic buttons and duress codes as tools that may help, with no promise of a particular result.
