Triggering Signals to Equipment within the System.
22
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).
3.3.2.2 Pulse Pattern Configuration
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.
[Pulse Pattern]
PULSE-1 ON 1s.
PULSE-1 OFF 4s
PULSE-2 ON 1s
PULSE-2 OFF 1s
HOLD PULSE ON 1s
Use the buttons to highlight the required pulse period
and then press the button to select it.
A menu of parameters is presented for the selected
sounder.

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.
Do not use SNDR3 for these functions.
ON normally takes precedence over PULSE patterns. Exceptions: during the pre-discharge countdown or during a hold condition.
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.
