APPENDIX I: Audio Evacuation & Life Safety Functions

Although not certied as a “Life Safety” system, RHAON has been designed to meet the stringent requirements of most Audio Evacuation /

Life Safety system specications.

Since “Life Safety” requirements vary widely from country to country and from one locality to another, we strongly recommend you contact

your local authorities for an opinion before proposing a RHAON system for any Life Safety application. They know best what’s required in

your area to meet code requirements.

A summary of RHAON’s life safety features follows.

Redundant CobraNet Inputs

All RHAON Empowered ampliers have a secondary Ethernet input that can be used to provide a “redundant” control and distribution sys-

tem. Such systems, of course, also require a redundant Ethernet system. Changeover to the secondary or redundant system is automatic

in the event the primary system fails.

Continuous Performance Monitoring

The performance of all RHAON Empowered Ampliers and Loudspeakers is constantly monitored for faults and abnormalities.

Event Logging and Notication

Pre-selected events are recorded in a Log le for later review and analysis; may be automatically forwarded via e-mail to another location.

Fault Monitoring

An opto-isolated input monitors the integrity of an external wiring loop by detecting the presence of a “sense” voltage and reporting its

absence via the Ethernet network.

Fault Relay

An isolated relay uses external wiring to report any amplier fault, the loss of the Ethernet carrier signal or the absence of a sense voltage

to associated monitoring equipment. Normally Open & Normally Closed contacts handle up to .5 Amp @ 28 Volts AC or DC. The detection

circuit functions either with or without the array being connected to a RHAON network. If the RHAON carrier is present when the array is

rst turned on, it reports if the carrier signal is lost; if the carrier isn’t present when the array is turned on it won’t report unless the carrier

signal suddenly appears.
