Dry pipe hose system control unit APIN-HM_CEN
Dry pipe hose system control unit model APIN-HM_CEN controls, operates and signals activation of the dry pipe hose system.

There are two possible arrangements for transmitting the dry pipe hose system activation signal:

• if the building does not have a fire alarm system in place, the alarm signal and malfunction signal are transmitted to the security company via a digital communication device,

The control unit model APIN-HM_CEN has a built-in module for operating shutdown of the dry pipe hose system.

System bleeder valves
System bleeder valves bleed air when the hydrant system is in operation thus ensuring rapid delivery of water to the hydrant cabinet. Bleeder valves are automatically closed by the hydraulic system when the water reaches the bleeder valve.

System drainage
Drainage of the dry pipe hose system may be envisaged using two methods:

• manual arrangement
• automatic arrangement.
