At least one relay module must be ordered with each 3300 System. If one common relay module per system has been ordered, all other monitors of this type will be jumper-programmed at the factory to activate relay bus one. Agency approval places limitations on the relay module. Quad Relays are not available with the Internal Safety Barriers option. AND voting logic is not available with Quad Relays.
Bold text indicates options as shipped from factory.
For Quad Relays, AND voting logic must be done externally by wiring the contacts in series.
