12. PA AMPLIFIER INSTALLATION
The optional PA amplifier & SMPSU (P/No. ZXT155) allows the onsite
manager to broadcast public address announcements through all
intercoms simultaneously.
Note; PA intercoms (P/No. ZXT206) must be fitted in all dwellings.
One PA amplifier & SMPSU can drive approx. 80 intercoms, for larger
systems a second ZXT155 will be required and the site PA wiring must
be split into two legs.
INSTALLATION
The PA amplifier & SMPSU is housed in a single steel enclosure 200x500x100 mm (HxWxD) designed for wall mounting
below the Advent xt controller.
MAINS SUPPLY
The 240V AC mains supply should be taken from the same fused spur as the Advent xt controller. Fit the nylon strain relief
to the socket to prevent the mains lead being inadvertently unplugged.
TERMINATION
3 cables are provided for connection to the Advent xt termination board - see table below for connections and colour
codes. See Drg No. ZXT100 sheet 2, for larger systems with intercoms split over 2 legs see Drg No. WD0276.

SMPSU & DC-DC MODULES
The 15V/100W switch mode power supply unit (P/No. W00586) is factory set to 13.75V DC output to supply the two 24V
DC-DC converters and the PA amplifier board. This voltage also charges the 12V standby battery.
The two 24V/50W DC-DC converter modules (P/No. W00590) are factory wired to provide +/- 24V DC supply for the PA
amplifier board. The DC-DC converters have solid state overload protection and contain no user serviceable parts.
PROGRAMMING
The All Call and Fire Tone options must be enabled in the “General Setup” programming - see the Advent xt Programming
Manual (Tynetec Doc No. FM0411).
