Primac* Systems were widely used throughout the munitions industry in the 1960's and 1970s. Primac* components are becoming expensive, scarce or obsolete. An upgrade to Pyrotech Rapid Response Deluge Systems through RAM, LAM and CPF-74 components is an efficient and cost effective method of suppression.
An upgrade to Pyrotech Pilot Operated Deluge may include using some of the existing piping, wiring and system components.
In many cases, upgraded systems will use the same types of Pyrotech components already in use and on-site in other buildings, simplifying use, maintenance and parts.
Contact Pyrotech to discuss options that may be available.
After firing of the squib operated systems, disc or caps and squibs must be replaced.
Solenoids are supervised for short, opens and grounds. On a squib operated system, the igniter wire can be supervised but condition of explosive is not known.
With electrical reset, the system can be reset (closing solenoid valves) with a key-switch, pushbutton or automatically by the RAM modules. There are no parts to replace.
An optional, automatic reset feature allows automatic reset after a preset time as long as no fire is present. The system is then ready to fire again automatically.
Due to low pressure prime and the remote location of the valve, air in the piping of a squib operated valve can cause slow and fluctuating response times.
Pyrotech deluge valves do not present the problem of bringing explosives (squibs) into the hazardous area.
Squibs have a shelf life and should be periodically replaced.
Mechanical manual release is possible even in the event of total power failure (including loss of primary power and battery back-up).
Pyrotech Pilot Operated Valves (CPF-74) can be interfaced with all types detection.
The LAM (Lowcost Accelerator Module) supervises and controls up to 4 solenoids. The LAM is a slave module to the RAM.
