Programmable features
The EST3X control panel includes a number of programmable features that can
be configured using the 3-SDU System Definition Utility (V5.02 or later).
• Groups: Allows you to create a collection of devices that are grouped in the
database in order to provide a group response that is separate from that of its
member devices.
• Custom audio messages: Allows you to record custom audio messages for
broadcasting through an emergency voice/alarm system.
• Automatic alarm signal silence timer: Determines how long alarm signals
remain active if they are not silenced manually. Possible values are 0 to
60 minutes.
• Reset inhibit timer: Ensures alarm signals are active for at least 1 to
60 minutes before you can silence them or reset the system.
• AC power fault delay timer: Delays reporting AC power failure off-premises.
• Waterflow silence: Allows you to silence alarm signals when a waterflow
device is activated.
• Zone re-sound inhibit: Prevents silenced signals from re-sounding when
another device in the same Zone group activates.
• Two-stage timer: Specifies the time you want to allow for two-stage operation.
The timer starts on the first alarm event.
• Trouble re-sound: Determines how long panel trouble buzzers can remain
silent with an active event on the panel. The buzzer re-sounds when the time
is exceeded. By default, this timer is set to 24 hours.
• Message routing: Routes messages to panels through network routing, or to
panels and printer ports using message annunciation routing.
