2-3.4 Electric Control Heads

2-3.4.1 ELECTRIC CONTROL HEADS

The electric control heads (Figure 2-31 and Figure 2-32) provide for electric and local manual

actuation of the CO

cylinder valve, or directional (stop) valves. The control head is operated

electrically by a suppression control panel and is equipped with a lever for local manual

operation.

The electric control head contains a microswitch whose contacts are used to break the electrical

circuit to the solenoid when the head is actuated. This reduces the overall power consumption

of the fire suppression system. The actuating pin latches in the released position and must be

mechanically reset.

A suitable suppression control panel, specifically listed and/or approved for use with the

following control heads, shall be provided for supervision of the releasing circuits per NFPA

requirements. In addition, a 24 hour back-up power source shall be provided per NFPA

requirements. Electrical data is contained in Table 2-8.
