• Wide Operating Temperature Range: Operates reliably in temperatures ranging from -25°C to +50°C (class A1) or -25°C to +65°C (class B).
• High Ingress Protection: Features an IP44 rating for protection against dust and water.
• Dimensions & Weight: Compact dimensions of 112 x 72 x 55 mm and a lightweight design at just 0.3 kg.

Principles of Operation:

The ZIS-PHD heat detector is designed to respond to temperature increases during a fire event. It can function as a fixed temperature detector when the preset threshold is exceeded, as defined by its sensitivity class. Additionally, it acts as a rate-of-rise detector when there is a sudden temperature spike. The detector's electronic unit, equipped with a measuring thermistor, continuously monitors temperature changes in its surroundings. Upon detecting a critical change, it transmits an alarm signal to the interconnected fire alarm control panel and activates the built-in LED diode, providing a visual indication of the alarm status.
