Radio Operation
The AMI can be used to access a mobile or base radio for wireless broadcasting. This application
requires connection of the AMI’s audio output (TB3-1 and TB3-2) and control output (TB4-7 and TB4-8)
to the transmit audio and PTT inputs of the radio’s accessory connector. This connection allows the
ACC2500 to broadcast live speech and alarm tones/messages over the RF airwaves.
N OTE : Radio audio levels can vary greatly between manufacturers. As noted in the “Specifications”
section of this manual, the AMI audio level output is 1 Vrms. Please contact our Service Department at
1-800-492-1212, prompt no. 2, if this level overdrives the radio input, as an attenuation circuit may be
required.
Page/Party ® Operation (Model 10959-908 Only)
The Model 10959-908 AMI is equipped with a Page/Party ® Interface PCBA, which can play messages/
alarms and connect telephone calls to a Page/Party ® system. It can generate a VLC tone during a
message/alarm that gives VLC-equipped Page/Party ® stations a signal to change the volume of the
message/alarm being played.
When interfaced to a Page/Party ® system, the operation of the AMI’s telephone interface is as previously
described, and includes all page modes. The selected party line is hardwired in the system, and cannot be
changed by the caller or the AMI configuration.
In addition to the telephone operation as described above, a user on the Page/Party ® system can initiate a
call by using Party Hot Dial. When configured via the ACT Tool, the AMI recognizes when a station
goes off-hook on the designated party line, and automatically dials the preprogrammed telephone number.
When the station goes on-hook, the call is terminated after the hang-up delay expires.
