The general fire alarm outputs can be used / configured to transmit triggering signals
to extinguishing system equipment such as pilot cylinders, warning devices, etc.
If required, the outputs can be non-silencing. These outputs can be individually
disabled (sounder-1 / sounder-2).

Activation of Alarm Devices with Different Signals.
Signals during the pre-discharge warning period should be intermittent and signals
during the activated / released condition should be continuous.
In addition to turning the sounders ON, the sounders can be pulsed as an alert tone. Three separate pulse
patterns can be configured.

From Software Version 2.02 :
A second ALERT pulse type (PULSE-1) is provided. The original ALERT pulse type is now renamed as PULSE-
2 and this is the default pulse pattern for the COUNTDOWN condition.
22
Do not use SNDR3 for these functions.
23
ON normally takes precedence over PULSE patterns. Exceptions: during the pre-discharge countdown or during a hold condition.
24
The mark to space ratio of the HOLD PULSE signal should be configured to create a different and unique pattern to the standard Alert
PULSE-1 or PULSE-2 patterns.
