Due to changes to transmission path faults in AS1670.1:2015 (clause 2.6e), there is a requirement to split the audio output of the individual emergency zone amplifiers into audio multiple feeds.
If the audio is required to be split at the panel, then there is a 4-way audio splitter (154-0280), with each audio feed capable of handling up to 100watts. The total audio power handled by the splitter is 250watts. Each audio feed is individually supervised and isolated. Up to two 4-way splitters (8 outputs) can be connected to each 120W EV3000 Amplifier, and one 4 way splitter (4 outputs) can be connected to each 40W EV3000 Amplifier.
A power supply (154-0278) is required for every 10 4 way audio splitters.
If the audio is required to be split remote from the panel, then there is a 2-way remote audio splitter (4210-0143). The audio feeds can handle up to 60watts each, with a total of 120watts per splitter. Each audio feed is individually supervised and isolated, and passes the fault condition back to the EV3000 audio amplifier.
The 2-way Remote Audio Splitter is available as a DIN mount.
