TwinflexPro² two wire fire alarm system


A conventional 2-wire fire alarm system is often the natural choice for smaller applications or where budget constraints exist.

Fike’s TWINFLEXpro² 2-wire fire alarm system has long been known for its adaptability and cost-effectiveness within a variety of applications, big or small … making it one of the most flexible products on the market.

Building on those strengths and designed for ease of use and state-of-the-art monitoring, the LPCB-Approved TWINFLEXpro² is the next generation in 2-wire fire alarm reliability.

The reliable fire protection system you can count on

This versatile fire alarm system incorporates Fike’s ASD Multipoint detector using smoke and heat detection with optional built-in sounder, allowing the whole system to be installed using only one pair of wires per zone. That means easier, faster installations AND cost savings.

Alarm Confirmation Feature 

Using the built-in alarm confirmation feature, until an alarm has been confirmed within an  individual area, only that area is evacuated.  At the same time, if an alarm is triggered in a  common area, the device initiates a full alarm  evacuating all surrounding areas. This unique  panel feature is vital where two- stage alarms are required.

For example – when an alarm is indicated by  an individual detector, the sounder for that  device/zone is activated and the control panel  carries out the configured number of  confirmation checks on that specific zone.

If the alarm is confirmed, the control panel  enters the fire state and all additional  notification devices are activated throughout  the facility. If the detector alarm is rejected,  the sounders on the zone are silenced, and  the detector in alarm is reset.

For safety, activating a callpoint will override  any delays or confirmation settings.
