Sigtronics Universal Y Adapter 6 Pin Installation Instructions
The Sigtronics Universal Y Adapter 6 Pin is designed to simplify the
process of connecting a Sigtronics Emergency Intercom System or a
MRIM-2 unit to your mobile radio.
Installation
1. To select an appropriate mounting location for the adapter, first
connect it up to the radio. To do this, unscrew and remove the two
screws on the top of the Universal Y adapter. Leave the lid in place
on the adapter for now.
2. Unplug the radio hand mic from the radio mic jack and plug it into
either one of the telephone type jacks on the Universal Y Adapter
module.
3. Plug one end of the short cable that came with the adapter into the
other telephone type jack on the Universal Y adapter.
4. Plug the other end of the short cable into the hand mic connector
on radio.
5. Now you are ready to select a mounting location for the adapter.
Select a spot out of the way so that the adapter and its cables will
not interfere with the normal operation of the vehicle. Note one
more cable will have to come out of the adapter for the wires that
go to Sigtronics intercom or MRIM-2 unit. This cable can come out
of any side of the adapter except the top. For convenience, the bottom of the adapter already has a hole for this. Make sure that the
hand mic has enough cable length to be used properly. If necessary
swap the hand mic and the short cable positions on the adapter
for best cable routing.
6. Hold the adapter on the intended mounting place and remove the
adapter lid. Mark with a pen or pencil through the two mounting
holes and the cable hole (if desired) on the bottom of the adapter.
If the cable to the Sigtronics intercom or MRIM-2 unit needs to
come out the side of the adapter mark that hole also. Note cable
holes on the side of the adapter should be as close to the bottom
as possible to clear the adapters circuit components. Drill all the
holes and mount with the supplied #10 sheet metal screws. Note:
As an option to using the sheet metal screws, the included double
sided foam tape may be used to mount the adapter.
7. Route the cable from the intercom or MRIM-2 unit through the hole
on the adapter. Note: Use the wire supplied with the Sigtronics
system for connection to the Universal Y terminal block. If unavailable use wire that has 22 or 24 gauge stranded conductors. Cut to
length but leave a few inches for access.
8. Strip the insulation from the individual conductors about 1/2 inch.
Twist the conductors to eliminate any loose strands. Using the
appropriate wiring pinout table insert the wires into the terminal
block holes. Note: Some configurations require that 2 wires be inserted into one hole. Two 22 or 24 gauge stranded wires carefully
twisted together will fit into one hole correctly. To insert the wire,
using a finger nail or small screw driver, press and hold the selected
orange tab down towards the circuit board and insert the wire into
the matching hole. Make sure the wire is inserted enough into the
hole that insulation touches the hole entry (no exposed bare wire).
Release the tab. Carefully inspect and fix any loose wire strands that
did not make it into the hole. Repeat for all wires.
9. Install the provided tie wrap securely on the intercom or MRIM-2
cable so that the wires won’t pull out of the adapter box.
10. Replace the adapter box lid making sure the wires do not get
pinched around the edges. Reinstall the lid screws.
NOTES: Don’t forget to also hook up the speaker wires (2 violet wires)
from the Sigtronics intercom or MRIM-2 unit to the radio speaker
leads. Adjust the Sigtronics intercom or MRIM-2 units transmit and
receive levels per their appropriate installation instructions. Your existing radio hand mic and speaker will still function as normal.
WARRANTY: One year parts and labor.
