The Telex MCE-325 User Programmable User Station is a 4-channel intercom station used to establish monitoring and communication within an RTS compatible intercom system. The MCE-325 may be used as a headset station or as a speaker station with the optional MCS-325 modular speaker. It's completely compatible with 2 or 4 wire intercom lines (or combination of both). An array of external sources may be interfaced with the MCE-325, including two-way radios, paging systems, satellite circuits and more.
Call signaling is accomplished using an inaudible (20 kHz) signal to activate a call indicator LED.
Instantaneous Auto Reset (IAR), the newest technology in performance and safety, which uses a revolutionary new circuitry that dynamically monitors line fault conditions. Then, when the fault is removed, automatically brings individual power supply channels up.
Active, unattended remote station microphones may be deactivated by momentarily injecting an inaudible (24 kHz) signal into the corresponding intercom line. The MCE-325 can send and receive "talk-off" signals.
The MCE-325 may be programmed for voice activation of the microphone.
Program audio assigned to a channel is interrupted during talk.
External Device Keying
External devices, such as two-way radios, speaker mute relays, or paging systems may be activated through key outputs at the auxiliary connector on the rear panel. The key outputs may also be used to expand the simple IFB function, allowing any one of a number of MCE325 stations to interrupt the program source and talk on the line.
The microphone preamplifier circuit contains a limiter, which helps to equalize voice levels.
Retains programming even when power is shut off.
