Supplemental Alerts
Alerting devices notify people working in noisy areas of outside, transferred,
and intercom calls. Connect an alert to one of the following:
■ Single-line telephone
■ MLX telephone with an MFM
■ Supplemental Alert Adapter (SAA) and analog multiline telephone
Alerts compatible with the SAA include horns, bells, chimes, and strobes. See
“Supplemental Alert Adapter” for installation instructions.
NOTE:
The MFM in SAA mode and SAA support devices operate on 48 V DC.
You can connect alerts operating on 20 through 30 Hz to an MFM in tip/ring
mode or a single-line telephone jack.
