The 52051RE-26 is an advanced analogue addressable heat detector, designed to detect either a fixed temperature of 58 °C or a rapid rise in temperature (Rate-of-Rise). It uses Type A1R detection logic, combining fast response to fire with low false alarm risk.
Part of the Series 200 Advanced Protocol family, it provides accurate, programmable detection in a wide range of commercial and industrial environments. The unit requires the B501AP base (sold separately) for mounting.
Key Features:
Dual detection: fixed 58 °C and Rate-of-Rise (A1R)
Addressable: uses rotary switches for easy configuration
Tri-colour LED: 360° visible status indicator (green, amber, red)
Advanced Protocol: part of the Series 200 range for enhanced communication and control
Compatible with legacy systems: backward-compatible design
Base required: B501AP (pure white)
