Alarm Attributes (PGM 227)
The System can monitor an external contact, most often employed as an Alarm indicator or
Doorbell. The Alarm attributes define the operation of the external contact. An Alarm Signal
sent to assigned stations can be repeating or a single burst, the former is often desired. For
the Doorbell, a single tone is sent each time the contact is activated (refer to the programming
table below for a description of the features, the data entries required and LCD displays for each
attribute).
1. Press the [PGM] button and dial 227.
2. Press the desired Flex button, refer to the following Table.
3. Use the dial pad to enter desired data for the attribute.
4. Press the [SAVE] button to store the data entry.
External Control Contacts (PGM 228)
The MPB includes 1 contact, which can be used to control external devices. The contact is
assigned to activate under one of several conditions: As a Loud Bell Contact (LBC), the contact
will activate when the assigned station receives an external call.
NOTE: When using LBC and the System is in the Night or Timed Ring mode, the contact will activate for
incoming UNA calls and will ignore any station assignment.
The contact may alternatively be activated as a Door Lock Release contact, when the External
Page Zone is accessed.
