- The specific resistance of the detector’s conductor pair is 0.191 Ohm/m.
- The diameter of the detector’s conductor pair is not more than 1.0 mm.
- The outer diameter of the alarm device is no more than 4.0 mm.
- The detector is permitted to be installed in explosive hazard zones.
- No extra requirements are needed for the detector.
- Connection to the fire alarm device is established through an intrinsic safety barrier.
- The service life of the detector is at least 25 years.
Advantages of line-type thermal detectors
- Affordable price. Protectowire thermocable is more affordable than other types of detectors.
- No maintenance costs. Line-type thermal detectors are maintenance-free, and their reliability and durability proven by over 80 years of global application.
- A wide range of models. Enables use in the most demanding operating
– environments.
– temperature from -40°C,
– explosive hazard premises,
– chemically aggressive media (sulfate and acetic acid, benzene, methanol, glycerin, oil, gasoline, butane, ultraviolet radiation, etc.).
- Savings on installation costs. Protectowire thermocable has a mounting span of 3 m, which is almost twice that of similar products.
