4.3 Calling the unit
4.3.1 2-wire operation
Calling the assigned extension number will allow the
unit to auto answer. The time to answer depends on the
unit’s internal ID and whether any faults are registered
on the unit (see Table 18). The unit’s ID is set at
configuration. Implementations requiring the primary and
secondary unit will have the 2-wire input connected in
parallel with the primary unit ID set to 1.
Unit ID
Time to answer
(no faults)
Time to answer
(with faults)
1
Typically, within 2 rings
Typically, within 6 rings
(delayed answer)
2-31
Typically, within 4 rings
(delayed answer)
Typically, within 8 rings
(delayed answer)
Table 19 – Answering times
Figure 8 – Primary & Secondary unit interconnection
Once the unit has answered, the user will be instructed
to follow a series of prompts or messages to enter
zoning information or be directed to leave a message
(see sections 4.4 and 4.5).
4.3.2 2-wire E&M operation
Calling the unit with E&M signalling requires no ringing
on the 2-wire audio interface. It will answer on receiving
an active key line on the E&M input of the telephone
interface input. The polarity of the E&M signalling is set
within the unit’s configuration (see the SAS manual for
details).
Once the unit has answered the user will be instructed
to follow a series of prompts or messages to enter
zoning information or be directed to leave a message
(see sections 4.4 and 4.5).
4.3.3 Auto-elevate messages
The unit has the facility to elevate the recorded message
to important message (emergency speech) status by
setting the configuration bit in SAS software.
When this feature is enabled, messages left after the
system has started broadcasting alarms will be given a
higher priority to override the alarm and broadcast the
message. Messages left before an alarm is broadcast
will maintain the lower priority and will not override
the alarm.
4.4 Zoning
The unit can be set to either global or zoned operation
by the front panel control or by loading the correct
configuration into the unit.
The Pbx has the ability to play a custom prompt to help
and guide the user through the available options. Please
contact Eaton for further information.
4.4.1 Global operation
Setting the unit to “global” operation as indicated on
the front panel will cause the unit to bypass the zoning
flow chart (see Figure 8) and prompt the user to leave a
message to be broadcast using the default zone list set
by the unit’s configuration.
