What are hazard alarm systems?
Hazard alarm systems (HAS) is a collective term for all types of alarm systems that are capable of independently recognizing dangers or reporting them via telecommunication technology. They are used to reliably warn and thus protect people and property against dangers such as intrusion, fire and robbery.
The term hazard alarm systems (HAS) includes the following types of systems, among others:
- Fire alarm systems (FAS)
- Intrusion alarm systems
- Smoke and heat extraction systems (SHEVS)
- Voice alarm systems
- Assault/Raid alarm systems
A number of VdS and DIN regulations must be observed for the installation and operation of HAS. If VdS certified systems are to be operated, these systems must be type-approved and may only be installed and maintained by VdS-approved installers.
