The ICM-8C series of Intercom Control Masters are ruggedized intercom panels for use in harsh environments such as correctional facilities while providing high quality audio communication with complete control. The ICM-8C series was designed to withstand physical attacks and deliberate abuse designed to disable the unit.
These units feature a 12 gauge stainless steel faceplate, vandal resistant steel selector switches and vandal resistant LEDs. The integral speaker and microphone are mounted in such a way to prevent physical damage to the components from objects and liquids that could cause these components to stop working. The chassis of the unit is constructed so users cannot introduce liquids inside to damage components and is constructed of rugged, powder coated steel. Field wiring for speakers and call buttons is connected to the unit using a industry standard 50 pin connector. A metal “keeper” prevents users from unplugging the field wiring and thus disabling the unit.
The ICM employs our unique intercom amplifier with discrete dual channel operation. Separate Operator and Remote amplifiers, AGC, level, and reach controls are used to provide complete control and quality audio. Both amplifiers are capable of 20 Watts of output into a 25Volt-industry standard speaker loads.
Operation – An internal jumper selects whether station selection is done by a single press of the associated steel button or by holding the station button for the duration of the conversation. Holding the button during the conversation keeps operators from selecting an unused station so as to never hear the call in tone over the speaker. An All Call button selects all stations for one- way paging announcements.

Options / Models
Scan – The Scan (“S” option) allows the operator to listen to each station sequentially when the intercom is not in use. As a station is scanned, the associated LED flashes and the operator automatically hears audio from the scanned station. If the operator hears something of interest, they press the button corresponding to that station and scanning is paused. When monitoring is complete, pressing the button a second time resumes scanning where it left off.
Alarm – The Alarm (“A” option) feature allows integration of external video switchers or alarm contacts with the ICM-8C. This permits connection of alarm contacts (inputs) for each station or connection to a video switcher (outputs). This “audio follow video” or “audio follow alarm” can be used in a variety of corrections applications.
