Fire alarm hvac shutdown relay.

Addressable control module could also shut down the hvac system in case a fire by a logic as required with hvac control ddc panel. The intelligent fire alarm relay. When placing a new fire alarm system in an educational facility a contractor may feel frustrated by the requirement to interface nonfire systems. Current configuration is a normally closed loo p wired r elay connection in hvac equipment s is not considerable relay to relay connection in hvac control panel and marshalling cabinet plc could be.

The alarm contractor is only willing to supply a signal to my hvac control panel to. This approach allows the fire alarm system to do what it does best detect notify and activate emergency controls while allowing an hvac system or bas to do what it does best manage the air quality of the building. Gamewell fci silent knight firelite notifier siemens and est edwards are just a few name brand examples. The intelligent fire alarm relay can only be used on intelligent fire alarm systems and is made specifically to work with particular brands of fire alarm systems.

The fire alarm system fas must either monitor or control these nonfire systems. Each monitor input provides an interface between a fire alarm control panel and one or more normally open contact type devices. When a fire alarm occurs it is common to shut down hvac equipment to reduce the spread of smoke and air to feed a fire. Traditionally integration between fire alarm systems and hvac systems has been limited to dry contact type relays.

The designer leaves it to the contractor to figure it out. In many such situations the fas designer will not have thought through the interface for each nonfire system. Each relay output is intended for form c switching applications which do not require wiring supervision for the load circuit. In some cases positive pressure fans are turned on to create a high pressure area in stairwells which keeps smoke out.

Our state mechanical code calls for smoke detectors to shut down an air handling device if it supplies more than 2 000 cfm. In either case these fans draw more current than a fire system relay is rated to handle. We have up to date information on the newest fire alarm trends such as fire service access elevators mass notification voice intelligibility occupant evacuation elevators and two way communication for areas of refuge.
