Tyco AutoPulse Z-10 - Programming the RAC Time Limit Cutout

Overview, Continued
The RAC Cutout Timer is a programmable timer that specifies the length of time the Releasing
Circuits are active. When the timer expires, the RACs “cut out”. This stops the water flow or
release of the extinguishing agent. This option is typically used on Deluge systems, and does not
work with all releasing systems and or releasing devices. (Some devices discharge their entire
supply of agent when fired so this setting would have no effect on operation.) A selection of “0”
means the RACs do not “cut out” and remain on until the system is reset.
