8.6 Alarm/Door Bell
The system can monitor external Alarm or Door Bell contacts:
Alarm Monitor—should the external contact activate, a unique
Alarm Ring signal and LCD display may be received. To restart
the monitor circuit, the external contacts must be deactivated
and the Alarm Ring signal terminated.
Door Bell—a unique Door Bell Ring (single tone burst) may be
received each time the external contact is activated. A system
contact also can be assigned to act as a Door Open contact.
To terminate the Alarm signal:
• Dial the alarm reset code (refer to Numbering plan (106~109)).
To activate the Door Open contacts:
• Lift the handset,
• Dial the Door Open code and contact number 1-2 or 1-4 (refer
to Numbering plan (106~109)).
8.7 Power Fail Transfer (PFT)
When AC power to the system fails, back-up operation may be
provided with back-up batteries or Power Fail Transfer (PFT).
When battery back-up is provided the station will operate
normally. When PFT is implemented, an SLT is connected to
a CO line by the system. This SLT can be used as any normal
SLT, providing service while power is out.
8.8 System Voice Memo
The integrated Voice Mail modules incorporate several Voice
Memos to provide Station Users with general information such as
station number, date, time, and feature status. Voice Memos are
heard over the Phone speaker and over the handset for SLTs.
For the Station Status Memo, the following items are reported:
Date and Time
Station number
ICM Signaling Mode (Handsfree/Tone/
Privacy)
