IP 101–4-PR (RO ASPZ)

IP 101–4-PR (RO ASPZ) Mine intrinsically explosion-proof heat fire detector

The IP 101–4-PR (RO ASPZ (РО АСПЗ)) is designed to detect fires by monitoring the ambient temperature (monitored fire factor), the dynamics of its change, and to transmit the current temperature value upon request from a fire alarm control panel (FACP) of the fire alarm system (SPS (СПС)) or another compatible device.
