Chapter 3 Universal Relay Controller Installation
The Universal Relay Controller (URC) is an extension of and an orderable accessory for O9 control
head. URC is used to control high power switching peripherals, e.g. lightbar. URC works on all
lightbars which can be controlled by power application. URC is connected to the transceiver's GCAI
port.
The URC design consists of a microcontroller and uses 10 relays to control the switching device. A
separate ground for isolation exists between the relay and MCU sections, which is provided by the
use of iCoupler from Analog Devices. Each relay is connected to an output with 15 A fuse. The
maximum load allowed on each output is 12 A. Two cables, each with the maximum of 60 A, can be
used to connect to the input connector at the bus bar. Each cable is connected with a 60 A circuit
breaker. One-wire EEPROM is employed to enable GCAI to recognize the URC accessory ID. CPS
can be used to program the relay patterns.
When installing URC, make sure to plan the installation carefully and leave additional room in the
front and rear of the box for cabling and accessory connections; and also to the sides of the radio so
that you may access and install the trunnion screws.
The recommended mounting location for URC is in the car trunk, either next to the transceiver or
within the area not further than 4.5 m away from the transceiver. Ensure that sufficient cooling is
provided. Do not cover URC with baggage, blankets, etc.
3.1 Universal Relay Controller Mounting
The mounting location must be accessible and visible. Select a location that permits routing the
cable as directly as possible.
NOTE: For optimum URC performance, orient the mounting trunnion as shown in Figure 3-1.
Figure 3-1. Universal Relay Controller Orientation
An adjustable trunnion, which allows a number of mounting positions, is supplied for mounting the
URC. The installation must not interfere with the operation of the vehicle or its accessories.
Do not backfeed power into URC.
