Esser 800271 ES Detect Rate-of-Rise Heat Detector

This heat detector measures the rate of temperature rise and, with its fast-responding semiconductor sensor, detects rapidly growing fires early. It also features a maximum value function; it triggers an alarm even when temperature rises slowly. It is preferred in warehouses, parking lots, and technical spaces. Because it has its own processing power, it performs automatic self-testing, stores alarm and operational records, and can be connected with a parallel indicator lamp.
