Bosch 5603 Single-circuit

Mechanical Heat Sensor or Detector

The Bosch 5603 is a professional-grade single-circuit mechanical heat detector designed for reliable fire detection in specific environments. Unlike smoke detectors, this unit is triggered by a significant increase in temperature, making it ideal for locations where smoke, dust, or moisture might cause false alarms, such as kitchens, laundry rooms, garages, or industrial settings. As a mechanical sensor, it operates on a simple and robust principle, providing a dependable and maintenance-free solution for your fire alarm system.

Features :

The Bosch 5603 is engineered with features that are essential for reliable fire detection. It includes both a fixed-temperature and a rate-of-rise functionality. The fixed-temperature element triggers the alarm when the ambient temperature reaches a specific threshold, while the rate-of-rise element responds to a rapid increase in temperature, providing early detection of a fast-spreading fire. The robust metal housing and simple mechanical operation ensure long-term durability and resistance to environmental factors that could damage more sensitive electronic components. This detector is designed for easy installation and is a crucial component for a comprehensive fire alarm system.

Advanced Options :

Beyond its core detection capabilities, the 5603 detector is built for seamless integration into professional fire and security panels. Its single-circuit design provides a straightforward connection to the alarm control panel. Its robust design and reliable performance make it a trusted component in a wide range of commercial and residential applications. The Bosch 5603 provides a professional and dependable solution for fire detection in challenging environments where other sensors may fail.
