Silent alarms for threats in the workplace.

Safety is often just a feeling.
We make it a fact.

Intuitive and unobtrusive: safety that works.

It is an unfortunate and disturbing trend – staff who work in direct contact with customers are increasingly being confronted, insulted and even physically threatened. Although this is predominantly a growing problem in the area of social services, other occupations are also being increasingly affected. 

What can you do to prevent this as an employer? Create genuine safety! Give your staff the certainty that they can discreetly call for help in an emergency – and receive backup as quickly as possible. With a silent alarm, duress alarm or armed-intruder alarm based on the novaalert alarm software.

FAQs - Silent alarms

A silent alarm must be transmitted as quickly and reliably as possible. To do this, a recipient group is first determined for the alarm message. In an emergency, these individuals are most likely to receive the alarm message via the novaalert desktopCLIENT on their PC workstations or via the novaalert mobileAPP on their smartphones.

The alarm message always has priority – this means it is always superimposed on the user’s screen or transmitted as a high-priority voice message. This alarm can neither be heard nor seen at the threatened employee’s workstation

The alarm message contains all necessary information, i.e. the name of the threatened employee and their location, which is displayed graphically on the building plan. Additional documents can also be pushed to each recipient’s screen, e.g. action plans or rules of conduct.

Each alarm message must be acknowledged. In other words, if nobody or too few people respond to an alarm message, additional personnel are alerted by means of escalation management. This ensures that every emergency call actually brings help

Depending on the existing infrastructure, a silent alarm can be transmitted in several different ways.

  • If the employee uses a PC workstation, they can trigger an alarm – without anyone else noticing – simply by pressing a key combination on the computer’s keyboard. The novaalert desktopCLIENT is installed on all PC workstations for this purpose.
  • With a suitable telephone infrastructure, help can also be requested by pressing a single button on the desk telephone.
  • Naturally, traditional emergency buttons can also be used to trigger silent alarms. These buttons are discreetly installed in hidden locations and can be operated inconspicuously. The installation effort for this solution can be reduced to a minimum by choosing monitored wireless pushbuttons.
