INSTALLATION

Installing Ignition Sense Wire Assembly

The ignition sense input is connected using the connector with the 22-foot red wire pre-installed in pin

6.The white jumper between pins 1 and 3 is not used

with this transceiver, so it can be clipped off or left as is. It is used only Summit® or Viking® HT/GT trans- ceivers to route audio to the internal speaker. The other connector and wire assemblies in the kit can also be used if desired.

The red wire from pin 6 (see Figure 2-4) is connected to a 13.6-volt source that is switched by the vehicle ignition switch. Connect this wire using the included fuseholder and 1-amp fuse. Be sure to install the fuse as close as possible to the connection point so that it provides optimum short circuit protection.

2.4.4 CONNECTING HORN ALERT WIRE

NOTE: The horn alert feature is not available with SMARTNET/SmartZone models.

To utilize the horn alert, the horn alert output of the accessory connector is connected and special programming is required. When the horn alert sounds, pin 4 of the accessory connector goes low. The disabled condition is a high impedance state.

Maximum sink current of the horn alert output is

500 mA. Therefore, some type of horn alert driver circuit is usually required. If connecting to a relay, a diode should be connected across the relay coil with the cathode toward the battery side. This protects Q100 on the audio/logic board when the relay de- energizes.

The horn alert output is connected by using one of the 22- or 2-foot wire assemblies included in the Accessory Wire Kit. Insert the pin of the wire assembly into the pin 4 slot of the connector as shown in Figure 2-4.Then connect the other end to the horn alert driver.

2.4.5 OTHER ACCESSORY CABLE OUTPUTS

Speaker Output (pin 1) - This is a low-level, volume controlled, speaker output. It provides drive to an external device such as an audio power amplifier. The input impedance of the external device should be greater than 20k ohms.

For this output to operate properly, the audio amplifier requires an 8-ohm load. Therefore, if not using the internal speaker and no speaker is connected to the external speaker jack, connect an 8-ohm, 5-watt resistor to the external speaker jack.

Sw Bat Out (pin 2) - This output can provide a switched battery output current of up to 1.5 A (including the current supplied to the microphone connector). This current is limited by fuse F100 on the audio/logic board. CAUTION: Do not change this fuse to one with a higher current rating because PC board damage may result.

Horn Alert (pin 4) - See Section 2.4.4.Ignition Sense (pin 6) - See Section 2.4.3.

Output D (pin 7) - This output is available with LTR- Net/Multi-Net models only. It is controlled by the menu OPTION parameter or by an option switch programmed for that function. It can also be controlled by several I/O functions (see Appendix B).

2.5 REMOTE CONTROL UNIT INSTALLATION

2.5.1 GENERAL

NOTE: Install the remote mount transceiver, power cable, and accessory cable as described in Sections 2.2, 2.3, and 2.4, respectively.

No special control unit programming or PC board modifications are required prior to installing the remote control unit. An diagram showing a remote installation is located in Figure 2-2.As indicated in this diagram, the control unit has a 5-ft pigtail cable and the transceiver has a 1-ft pigtail cable. These cables can be directly connected if the control unit is mounted within approximately 6-ft of the transceiver. Otherwise, the optional 11-ft extension cable can be used to allow a mounting distance of up to approximately 17 feet.

2.5.2 MOUNTING REMOTE CONTROL UNIT

1.Check the area underneath the selected mounting surface for such things as wires, electrical compo- nents, and brake and gas lines that could be damaged when the mounting bracket screws are
