A two-wire fire alarm system is based on conventional system technology and is often the choice for smaller applications or where budget constraints apply. These systems are great solutions for meeting safety and security requirements whilst maintaining a lower cost.
Two wire systems work by allowing detectors, call points and alarm devices for each zone to be wired on the same set of two-core zone cables back to the control panel. This enables it to use a single circuit per zone without the need for a separate sounder circuit zone. This will furthermore reduce installation costs and time.
