Door Bell function
Although the PRT32 is not equipped with any special functional key which would be
solely dedicated to operate as a door bell button it offers an alternative mechanism.
In order to trigger a
Door Bell
output user must press [#] key for more then 2s.
The indication of a door bell is accompanied by continuous sound generated by the
internal buzzer.
Note: In PRT32 the long press of [#] key is treated as Door Bell button while the
use of [#] key which follows digits of a PIN code is used to mark the end of a PIN
code.

Alarms
The PRT32 reader can detect and indicate following type of alarms:
•
Forced Entry
•
Prealarm
•
Door Ajar
Forced Entry and Door Ajar alarms will occur only if the reader operates with a
Door Contact
. The alarm indication is carried out over the
Alarm Output
line and
optionally accompanied by the internal buzzer (see option:
Door alarm indication
on internal buzzer
). For each type of alarm the PRT32 uses different signal
modulation of an output.
