Horn Alert FunctionThe Horn alert function (max. 2A drive) is enabled by in-stalling the KCT-60 in the transceiver.INSTALLATION2-1. Installation Procedure1. Remove the ACC. cap on the rear of the transceiver.2. Connect the D-sub connector of the KCT-60 to the D-sub15-pin terminal of the transceiver.3. Insert the two crimp terminals of the Horn alert cable topins 13 and 14 of the square plug.4. Connect the square plug to the 15-pin connector of theKCT-60.5. Connect the remaining two Horn alert cables to your carHorn alert signal control.The internal FET switch can be controlled by turningthe HA function on/off and by using a signaling decodeoutput. The maximum current of HA is 2A. This switch isthe FET switch of P-channel type. Therefore, a DC powersupply is necessary to use the HR1. The voltage range isfrom 5V to 16V.Note: You must set up using the KPG-141D.3. Ignition Sense Cable (KCT-18: Option)The KCT-18 is an optional cable for enabling the ignitionfunction. The ignition function lets you turn the transceiverpower on and off with the car ignition key.3-1. Installing the KCT-18 (Ignition sense cable) inthe transceiver1. Connection Cable (KCT-60: Option)The KCT-60 connection cable kit is used to connect thetransceiver to a Horn alert cable, KCT-18 (Ignition sensecable), KES-5 (External speaker), or through the KCT-36 ex-tension cable.1-1. Installing the KCT-60 (Connection cable) in thetransceiver1. Remove the ACC. cap on the rear of the transceiver.2. Connect the D-sub connector of the KCT-60 to the D-sub15-pin terminal of the transceiver.3. Connect the 15-pin connector of the KCT-60 to a Hornalert cable, KCT-18, KES-5, or through a KCT-36 exten-sion cable.Note: You must setup using the KPG-141D.Horn alert cable,KCT-18, KES-5 or throughKCT-36 extension cableKCT-60Horn alert cable,KCT-18, KES-5 or throughKCT-36 extension cable13.
