3.5.1 Overview

Figure 3-56 Fire linkage principle
● If the pre-fab. module catches fire, the extinguishant control panel sends dry contact signals
in the first stage alarm to the access actuator to release the access control.
● If the pre-fab. module catches fire, the extinguishant control panel sends 24 V DC signals in
the second stage alarm to the power distribution box used for switching off non-fire
extinguishing loads. Then the shunt release trips and the fresh air fan shuts down.
If the pre-fab. module catches fire, smoke and heat will trigger the smoke and
heat detectors, which will send fire alarm signals to the extinguishant control
panel. Upon receiving the fire alarm signals, the extinguishant control panel
counts down and then opens the electrical actuator on the fire extinguisher so
that the fire cylinder discharges extinguishing agent to the protection zone. At the
same time, the extinguishant control panel automatically reports alarms.
