ZP2-A Series Operation Manual
Control/LED
LED colour Description
Sounder Start/Stop
button and LED
Red
The LED indicates what happens when the button is
pressed:
If the LED is on (flashing or steady), pressing the
button silences the sounders.
If the LED is off, pressing the button activates the
sounders (if the control panel status and operating
mode allow manual activation of sounders).
The LED also indicates the status of the sounders:
• Steady indicates that sounders are active (or will
be activated shortly)
• Flashing indicates that a delay is counting
(sounders are activated when the configured
delay elapses or when the delay is cancelled)
• Off indicates that the sounders are off (or will be
deactivated shortly)
To prevent the immediate silencing of sounders
when an alarm is first reported, the Sounder
Start/Stop button may be temporarily blocked when
a configured sounder delay is counting down. For
more information, see “Stopping sounders or
restarting stopped sounders” on page 26.
Depending on the size of the installation, processing
commands to start or stop sounders may take a few
seconds to travel through the system. This is why,
for example, the LED may be steady but sounders
may not initially be audible.
Panel Silence button and
LED
Yellow

Reset button and LED
Yellow
Resets the control panel and clears all current
system events.
A steady LED indicates that the control panel can be
reset in the current access level.
