Description
The C-TEC ACTIV C4 EN54-5 A1R Heat Detector (C4403A1R) is a high-quality conventional fire alarm heat detector designed to provide reliable detection where heat detection is more suitable than smoke detection. Manufactured in the UK by C-TEC, this A1R rate-of-rise heat detector is third-party certified to EN54-5 by Intertek and is designed for use with conventional fire alarm systems.
The C4403A1R provides effective fire detection by responding to both a rapid increase in temperature and a static temperature within its specified response range of 54°C to 65°C. Its wide 9–33V DC operating voltage and low quiescent current make it suitable for a wide range of compatible conventional fire alarm applications. Two ultra-bright red LED indicators provide 360° visibility, making alarm indication easy to see from different directions.
Designed with reliability and straightforward servicing in mind, the C-TEC ActiV C4403A1R is compatible with the C4408 non-diode and C4408D diode detector bases. The ActiV range features a simple click-and-twist design, while the compatible bases incorporate an integrated locking mechanism to help prevent tampering. For installers and fire alarm professionals looking for a dependable EN54-5 conventional heat detector, the C4403A1R is a practical choice for suitable fire detection systems.
