Mounting The Radio - Tait TM9155R Installation Manual

The radio allows for output to external alert devices using the digital GPIO

lines of the auxiliary connector and the internal options connector.
AUX GPIO4 can be fitted with a power MOSFET (Q707) to directly
connect external alert devices (e.g. flashing light, buzzer, horn relay) to the
radio. Also, resistor R768 must be removed.

Mounting the Radio

Once the cables are all in position, you attach them to the radio and secure
it in its mounting location. The procedure varies, depending on whether
you are using the base plate and cover.
Warning!! Mount the radio securely so that it will not break loose
To mount the radio without using the base plate and cover:

must be used. For more information, refer to the service manual
and the online help of the programming application.
Connect a normally open switch between the pin of the input line
(pin 5 for AUX GPI2) and pin 15 (AGND) of the
auxiliary connector.
While the MOSFET is rated at 12 A (with heat sink), the
maximum allowable current of the connector and radio's
earthing system is 2 A. Therefore, a horn must not be
connected directly to the radio. A horn relay must be used.
The selected output line must be programmed to 'External Alert 1
or 2', active to 'Low', and signal state to 'Momentary'.
Connect the external alert device to the pin of the output line (pin 10
for AUX GPIO4) and pin 8 (+13V8 SW) of the auxiliary connector
(or a different positive battery connection).
This means that the negative side of the alert device must be con-
nected to AUX GPIO4 and the positive side to pin 8 (+13V8 SW).
The external alert device must be capable of accepting a voltage of
between 10V and 18V.
in the event of a collision.
Locate the 110W Mobile chassis in the mounting location and drill
mounting holes.
Connect the Control Head cable, Antenna cable and External
Speaker (if installed). Lastly, connect the power cable.
Fix the 110W Mobile chassis securely to the mounting surface.
