The ICA-202D+PA-402+RM2 combines Tech Works ICA202D with PA-402 in one RM2 saving space and installation time.
The Tech Works ICA-202D is the most versatile Audio Intercom available; yet it is also the easiest to integrate into your design. With 20 watts of clean audio power at 25-Volts it can do both the Intercom and the Paging functions in most facilities. The audio quality of the ICA-202D is superb. Noise and distortion are very low. Selectable equalization optimizes voice communications.
There are separate controls for Audio Level, and Reach. Once set, Automatic Level Control (ALC) assures the speaker level remains constant over a wide dynamic input range. The Remote user may wander throughout the room and still be heard at a nearly constant level without any operator adjustments.
All configuration settings are factory presets; only the speaker levels are set in the field. The microphone sensitivity (Reach) is preset with 16 position (3dB/Step) switches; the Speaker Levels are adjusted with Back Panel Controls. External Control allows the Operator to listen to very low sounds or soft speech from the remote station. The Remote Microphone Sensitivity (Reach) is fully controllable; set by a Front Panel Control, and/or Console Push Buttons, or PLC Touch Screen. ALC keeps the Speaker and Recording levels from exceeding preset levels.
A Privacy Tone, to alert the remote party that someone is listening, is a control option. If selected the privacy tone will sound every 20 seconds unless the PTT is pressed. Electronic switching takes less than 3mS. Audio Switching Delay is adjustable to eliminate the reverberation in difficult “hard acoustic” places like holding cells.
The logic interface is PLC compatible including stepped external “Level Control”. Input control options include Privacy Tone, Page, PTT, Mute, Activate, Shut Off, and Call Tone, which is automatically routed to the operator speaker. A Line level output for recording is included. A separate Page line level output provides audio to paging amplifiers if required. A Page Pre-Announce Tone (jumper option) is available.
The PA-402 is a Professional Audio Power Amplifier designed with the System Integrator in mind. It is specifically designed for Background Music, and Paging Applications and may be used with other Tech Works products to augment a variety of system designs. The PA-402 has Program Audio Inputs, Paging Audio Inputs, and Control signals that select which Audio inputs are directed to the Speaker. These inputs are transformer balanced allowing several PA-402’s to be connected in tandem, for large distributed systems. There is also an unbalanced Stereo Input for “Local” Music insertion.
The logic allows for a wide range of control requirements including; Enabling, Muting, Program, or Page selection. Logic options are selected from a set of dipswitches located on the rear of the amplifier. The PA-402 comes ready to use for most applications, and there are Application Templates for other common uses.
The audio quality of the PA-402 is superb. The undistorted output is 40-Watts. The PA-402 is fully protected against overloads. The unit automatically recovers when any overload is removed.
Modular Construction makes the PA-402 ideal for integrated designs. The unit is small; mounting is flexible, and easy, so it is ideal for space conscious requirements. Mounting options include Desk Mount (DM), Rack Mount (RM), and Wall Mount (WM). All signals are connectorized for ease of installation.
Power is from a Universal Plug-in DC power adapter or screw terminals for connection of any regulated 24VDC-3.5 Amp Power Supply (Sold Separately).
The Tech Works RM-2 Rack Mounting Kit is designed for use with our 1 rack unit high by half rack unit wide products. These are metal components with powder coat paint for use in EIA standard 19-inch equipment racks.
The RM-2 includes two short ears and a double wide metal top and mounting screws. To install the RM-2 you simply remove the Desk Mount tops of the two units to be mounted and place them side by side on the bench. Place the doublewide top on the two units and replace the screws. Then using the rack ear screws that come with the kit you attach the short ears to the outside of the package. Remove the back labels from the original Desk Mount tops and place them on the back of the completed unit.
