Meridian External Alerter and Recording Interface (MEARI)
The MEARI provides a remote ringer device installed in a location separate
from the telephone. The MEARI provides access to a standard, off-the-shelf
remote ringer, call status relay, audio recorder or visual indicator.
Program the MEARI interface to activate a ringer (or light) when the telephone
rings, or activate a recorder when the telephone is in use. The MEARI requires
an Accessory Connection Module (ACM).
MEARI connects to any M3900 set except the M3901 set, which has no
accessory dock. In order to use the MEARI accessory, the telephone must be
equipped with the M3900 series ACM and power supply (purchased
separately).
The MEARI provides relay contact outputs for both ringing and call status
(off-hook condition) for activation of third party peripheral products such as
loud ringers or call-in-progress indicators. Additionally, the MEARI provides
an audio output connection to voice recording equipment (as permitted by
law).
