2-3.6.2 HEAT ACTUATED DETECTOR
The pneumatic heat-actuated detector (HAD), Part No. WK-840845-000 (Figure 2-38),
consists of a sealed hollow brass chamber having no moving parts. The detector is connected
to the pneumatic control head(s) by copper tubing. The air pressure in the detector increases
upon a rapid rate-of-rise in temperature, such as in the event of a fire. This pressure increase
is transmitted to the pneumatic control head(s) via the copper tubing, causing the control head
to actuate the system. The pneumatic heat detector, tubing, and pneumatic control head(s)
system is vented to prevent normal ambient temperature changes from actuating the system.
