Note: If non-polarised alarm devices (eg some types of old mechanical bell, or a relay) are used, then
a diode will have to be placed in line with the device to enable fault monitoring. They may also need a
back EMF protection diode. (symptoms: Chattering sounder relays that don't turn off).

8.2 ADDRESSABLE SOUNDERS.

On the Premier AD, addressable sounders (the ones that take a loop address) can
be configured to operate on a zonal basis if required. If the sounders are in the
same group as an input device (Detector, MCP or I/O unit), then it will operate on an
alarm from that zone only. If there are no inputs in the same zone as the sounder,
then it will operate on any alarm.
(Note that the Premier AD has a preset "time out" of 3 minutes, after which, ALL
loop sounders will start, even one from a different zone)

8.3 ASSOCIATED SOUNDER BASES

Associated sounder bases (also known as platform sounders) do not communicate
with the fire alarm panel. They are controlled by the detectors remote output signal.
This means that when a panel configures the loop, it can not see these sounders.
The Premier AD assumes that any detector could have one of these sounders
connected, so when an alarm signal comes, the panel sends the "turn on your
remote output" to EVERY detector. This makes their operation slower than standard
addressable detectors.
If not every detector has a sounder base fitted, it might be possible to speed up the
sounder base start/stop time. See configuring sounder bases on page 19
8.4 SUPPORTED SOUNDER TYPES & THEIR APPLICATIONS
The Premier AD supports 4 general sounder types; conventional, addressable, addressable sounder
controller, and associated sounders. All types have advantages & disadvantages.
Sounder type Advantage
Conventional Wide range of devices
Devices tend to be cheaper.
Immediate start / stop
No quiescent current
