1.0 GENERAL. 1.1 FEATURES. The Model 1241 is the most sophisticated Two Way audio device on the market today. Features include: ♦ Central station detection and automatic disconnect upon central station disconnect. ♦ Compatibility with all digital communicators. ♦ Microprocessor technology which provides a wide range of operating modes. ♦ Activation by a trigger input immediately after the communicator hangs-up and/or by its built-in ring detector by calling the system back after the alarm report.
2. A Touch-Tone phone in parallel with the receiver line if used in the line hold mode. 3.0 CONFIGURING THE MODULE. 3.1 OPTION SWITCH DESCRIPTION. The Eagle Model 1241 has many modes of operation. It can be custom configured for each installation. The following is a description of each of the option setting switches. Recommended settings are italicized. NOTE: When changing the Option Switches, always remove power, set switches, then reconnect power.
The module may be switched into either mode and back again (as many times as desired) independent of which mode it was initiated. Recommended setting for SW3 is OFF. ______________________________________________________________________ SW4: ON = Activate the system from ring detector. (Note: system will also activate with trigger input when in this position, dependent on SW5.) OFF = Activate the system with the trigger input ONLY (disable ring detector). This switch controls the full-time ring detector.

P3 - This sets the type of microphone used on MIC1 (only). Set the shunt block across pins 1 and 2 (default) when using an electret microphone (Eagle Model 2101). When using an amplified microphone, set the shunt block across pins 2 and 3.
Speakers. The Model 1241 is designed to drive up to four speakers. Total speaker impedance must be eight (8) ohms or greater. (See section 3.2 for wiring diagram.) If additional speakers are required, or if additional volume is desired, the Eagle Model 1402 SPEAKER EXPANSION MODULE must be used. 3.6 COMMUNICATOR PROGRAMMING. When programming the digital communicator, it is advised to begin the "TELEPHONE NUMBER" with "∗ ∗ 70" (tone dialing) or "1170" (pulse dialing).
When the system detects the programmed number of rings, it will pick up the phone line and send a series of 3 "beeps" as an answer acknowledgment. The system now has the line, but Two Way is NOT active. The operator has 15 seconds to press (and release) the * (asterisk) key to activate the module. If the * is not sent in 15 seconds, the system will hang-up. When the * is received, the system will generate a two tone "beep-bop" acknowledgment and the red LED will illuminate.

sent is when the module is used in the "listen-in only" mode for the duration of the call. To shut down the module, press and release 9 at any time. To shut down the module and initiate the five minute call back window, press and release 8 at any time. This will allow the central station or any other party to call back and have an active Two Way session. (This is beneficial when a home or business owner wishes to listen-in after the central station has finished.

P2 - MODEL 1400 AUXILIARY RELAY MODULE This module provides an additional DPDT relay which is activated when the audio module is activated. It is automatically de-activated when the module shuts down. The color code on the Model 1400 wire harness is the same as the cable supplied with the audio module. P4 - MODEL 1402 SPEAKER EXPANSION MODULE. The Model 1402 provides three additional speaker outputs.
7.0 ADDITIONAL INFORMATION. 7.1 INSTALLATION TIPS. ♦ Microphones and Speakers must be a minimum of 3 feet apart. ♦ Do not place microphones at or near devices that generate loud ambient sounds. ♦ Do not place microphones in heating ducts. ♦ Do not place microphone at or next to keypads that contain an internal piezo unless it is disabled. ♦ Always, always use shielded cable for all microphone runs. ♦ Full time call back mode is not recommended for most installations.
8.0 FCC REQUIREMENTS. 1. The Federal Communications Commission (FCC) has established Rules which permit this device to be directly connected to the telephone network. Standardized jacks are used for these connections. This equipment should not be used on party lines or coin lines. 2. If this device is malfunctioning, it may also be causing harm to the telephone network; this device should be disconnected until the source of the problem can be determined and until repair has been made.
