Heat Detection Tube

Heat Detection Tubing is a new fire detection system implemented by Clean Air Industries since January 2020. The tubing runs along the wall in the filter compartment. When temperature reaches 375 o F, the tube bursts and immediately releases the fire suppression agent. The heat detection

tubing is implemented to allow the system to release the fire suppression agent during power loss.

The heat detection tubing comes with pressure switch to monitor whether the fire suppression agent

has been released.

FSS Pressure Switch

The pressure switch monitors the pressure in the

heat detection tube. When the tube bursts, the

pressure in the tube will drop. This triggers the

pressure switch, which will then send signal to

the PLC to let the PLC know that the fire

Strobe / Horn

The fire strobe and horn are built into one unit operated by

24VDC. Typically, the fire strobe is mounted to the front of the

electrical door. On some applications, remote fire strobes are

mounted for indication elsewhere in the facility. When the alarm is

activated, an auditory horn will sound and a flashing strobe light

will be visible.
