The Siemens collective heat detector is designed for applications in harsh environments where dust, moisture, fibers or corrosive vapors would make conventional smoke detectors unsuitable.
Based on a high-precision thermal sensor, this device offers high reliability in detecting rapid temperature increases (thermovelocimetric) and monitoring the attainment of fixed thresholds, according to the A1R classification, in accordance with EN 54-5.
The detector body is constructed of shockproof and tamperproof materials, while the internal electronics are protected from electromagnetic interference, vibration and temporary condensation.
It is therefore ideal for:
Industrial environments
Dusty warehouses
Areas with high humidity
Installations with forced ventilation
A built-in 3-color LED, visible from any angle, indicates the detector status (normal, alarm, error). Up to 2 external alarm indicators (type FDAI91/92/93) can be connected, for installations requiring remote visibility.
The module uses signal processing algorithms to ensure reliable performance, and features drift compensation and built-in error monitoring.
Compatible with standard Siemens 110z series bases
Suitable for both surface and recessed installation
Compatible with exchanges on collective and conventional lines
IP40 degree of protection (expandable to IP42 with RS720 base seal)
Workshops and industrial laboratories
Tunnels, basements and garages
Areas subject to rapid temperature changes
Environments where smoke detectors would generate false alarms
