conditions for the installation of this equipment.

Conexões e Chicotes

Together with the equipment are supplied pigtails with connectors to make each
wiring harness. (Example shown in the enhanced area in figure 3). It is of extreme
importance that the sections about wires in Table 3 be respected and followed closely.

Table 3: Section of the wires for connection

A fuse should be added to the wiring harness (Figure 3) close to the battery to
prevent damage to the electrical system of the car by short circuit.

External Siren (input of signal for siren selection)

This input is a signal to select between tones of the siren, normally it is used in
undercover vehicles. This should be connected to a ground through a momentary
selection switch, each pulse of this switch will navigate between the tones Pierce > Yelp
> Hi-Lo > Wail > Off. Maintaining the switch pressed for more than a second and a half,
turns the siren off.

Input for Hands Free function

The RT1000 possesses a button in the front panel used to activate the Hands
Free function. When this function is active the internal relay will be activated,
deactivating the horn, and making the horn button function as the siren selector
according to table 6.

NOTE: When this function is active, the vehicle horn will not function.

To deactivate the Hands Free function, press the same button on the panel again.

IGNITION input

The IGNITION input should be connected to the vehicle key switch, in the fashion
that the equipment only functions when the key switch is on. If the user does not want
to use this function, this input should be connected to power (+12 or +24V). Table 7
shows the logical functioning of the input together with the I-Saver feature.

I-Saver Input
If this input is activated the moment that the function IGNITION is activated, the

siren will wait for 4 hours before deactivating. This function is activated when
connected to the battery positive.

Battery management function:

The LED indicator of the low battery will be activated if the power voltage reaches
the critical level of 10.9V for the 12V model and 21.9V for the 24V model, for more than
25 seconds. At this voltage it is still possible to start the vehicle. Once the LED is on, all
the functions are turned off. Take this chance to start the vehicle to recharge the
battery.

IMPORTANT: In situations when it is necessary to use the functions of the RT­1000, even when the battery is low, the users need simply press the button of the
function he/she desires and the equipment will function as normal. The Low Bat LED
will remain lit until the level of the battery is 13.3V for the 12V model and 26.6 for the
24V model.

Table 9: Logic of the low battery function

Low Bat – Output 7 (low battery signal)

Similar to the battery management system, this output will be activated (+12 or
+24V) if the power voltage falls below the critical level of 10.9V for the 12V model and
21,9V for the 24V model for 19 seconds. At this level it is possible to still start the
vehicle.

This output will only be deactivated when the voltage returns to a level of 13.3V
for the 12V model and 26.6V for the 24V model.

This output allows you to trigger some external device, for example alarms, relays, etc.
The power of this output is limited to 250 mA.

This output, associated with the front LED (previous topic), signals that the battery is at
the critical threshold. See table 10 below, the voltage values for both amp models:

Radio Inputs

RADIO 1 and RADIO 2 inputs must be connected to the audio outputs of the radio
to be amplified in the siren output when the RADIO function is enabled in the
Panel. To adjust the volume of the siren output function a secondary volume
adjustment is used and located on the buttons AUX2 (increase) and AUX3
(decrease). See Figure 9. To adjust the volume, press and hold for more than 1s a
while the RADIO function is triggered or while speaking into the microphone with
PTT pressed.
