Vaughan, ON – The Mircom Group of Companies, a global provider of advanced fire life safety systems and communication products is pleased to announce that the Mircom FR-320 Releasing Control panel has been enhanced with the addition of three new modes of operation. This provides this panel with additional flexibility by expanding the total to 14 different modes of operation.
The FR-320 has three new UL/ULC listed modes of operation which provide additional flexibility. The new modes are as follows:
Mode 12: Pre-Action/Deluge, Single hazard, Cross Zoned, Combined Release
Mode 13: Pre-Action/Deluge, Single Hazard, Not Cross Zoned, Combined Release
Key Features for Modes 12 & 13: The addition of a second supervisory zone allows one zone to be used for supervising the valve, and the second to be used for supervising the pressure. A separate zone to supervise the valve and the air pressure is required by many codes.
Mode 14: Pre-Action/Deluge, Single Hazard, Not Cross Zoned, Combined Release
Key Feature for Mode 14: This mode allows NAC 1 to be on steady and NAC 2 to be on temporal at the same time allowing NAC 1 to power strobes (for first stage alert to the building before the release is actually active) and NAC 2 for actual signaling at the same time.
The FR-320 is a field configurable releasing control panel that operates with the following types of systems:
- Wet Pipe System The most common type of sprinkler system is the wet pipe, which contains water under pressure in the sprinkler system pipes at all times. The system uses closed sprinkler heads.
- Dry Pipe System Similar to a wet system, but does not contain water above the clapper. The system side is filled with compressed air, which holds back the water supply by keeping the clapper or “dry pipe valve” closed.
- Pre-action System Similar to a dry-pipe system in that the water is kept from entering the piping by a “pre-action” valve. Closed sprinklers are used on piping that is filled with air that may or may not be pressurized. A supplemental electronic fire detection system (separate from the main building fire alarm system) is also installed, serving the same areas protected by the pre-action system.
- Deluge System Similar to a pre-action system except the sprinklers are open type. They are not kept closed by a fusible link. The water supply is kept from the system by a “deluge valve” which is released by the activation of supplemental fire detection such as fire detectors (heat or smoke). Once water flows through the system, it is discharged by every sprinkler head in the system.
With these new modes of operation and the additional seven solenoids that were approved for use late last year, the FR-320 Releasing Control Panel provides a great solution for high value applications such as computer rooms, libraries, museums and banks. This powerful system provides pre-action, deluge and agent release functionality in one field configurable panel.
