I am an electrician working for Vancouver Island Health Authority. At one of our hospitals, a new Simplex Grinnell addressable fire alarm system (with a 4100ES Panel) is being installed. Voice communication is being used for paging, alert signal, alarm signal, and emergency telephone. CAN/ULC-S524-06 Clause 4.5.1 D
directs that where the building is sprinklered, that a fault within one floor area shall not prevent voice communication in another. Is the fault referred to in the data loop serving active field device, and/or supporting field devices or does this refer to a fault in a voice communication circuit. In other words, does one have to split up voice communication speakers into different circuits when they serve different floor areas?
Thanks
