Control Wire Harness (Connector B)

● Speaker Out

Connect the LIGHT BLUE (SPK+) and BLUE (SPK-) wires to one 100W 11-ohm impedance speaker.

● Ignition Activation (IGN) input

Apply +VDC continuously to RED wire to enable the siren system. Connect this wire to a positive

circuit controlled by the vehicle ignition switch to allow the siren amplifier to be turned on & off together.

The system does not operate without this Ignition Activation. DO NOT directly connect this wire to the

battery as this may drain battery.

● Siren Tone Activation

Apply +VDC continuously to BROWN wire to activate the siren tone. The siren tone will only sound if

the Siren Interlock (WHITE) wire is enabled. For tone selection, see page 7 for Tone Group Selection.

● Siren Interlock input

Apply +VDC continuously to WHITE wire to enable the activation of siren tone. Connect this wire to

the switch output of a beacon or the primary warning light. The siren tone will only sound when this

wire is enabled with the Siren Tone Activation (BROWN) wire.

Note: If siren interlock is not required, connect this wire directly to the positive (+) battery terminal.

● DAY/NIGHT Volume

Apply +VDC continuously to ORANGE wire to activate volume dimming of siren tone (reduced output).

This function does not affect the sound output of Air Horn, Mic volume.

Base on the Tone Group setting, this wire may be used for tone change. For actual function of this

wire, see page 6 for Tone Table.

● Horn Ring Transfer (HRT) input

When the Siren Tone is not activated:

- If WHITE wire is enabled, apply +VDC momentarily to PINK wire for two cycle of the Siren Tone or

apply +VDC continuously for a continuous Siren Tone until the wire is released.

- If WHITE wire is not enabled, apply +VDC continuously to PINK wire for Air Horn tone until the wire

is released.

- Base on the Tone Group setting, this wire may sound or behave differently. For actual function of

this wire, see page 6 for Tone Table.

When the Siren Tone is activated:

- Apply +VDC continuously to PINK wire for Air Horn tone until the wire is released.

- Base on the Tone Group setting, this wire may be used for tone change or behave differently. For

actual function of this wire, see page 6 for Tone Table.

This wire may be wired to a positive or a negative source based on the DIP switch setting. See page

6 for DIP SWITCH SETTING.

● Mix Tone

While Siren Tone is activated, apply +VDC continuously to YELLOW wire for Mix Tone function. This

function allows the siren speaker to deliver two siren tones simultaneously for a fanfare effect and increase

Siren effectiveness. Base on the Tone Group setting, this wire may sound or behave differently. For

actual function of this wire, see page 6 for Tone Table.

● Radio Re-broadcast

Connect GREY and GREEN-YELLOW wire to the speaker output of a radio console. Apply +VDC

continuously to PURPLE wire to re-broadcast the incoming radio messages over the siren speaker.

● Record-n-Play

This function allows user to record a short message up to 20 seconds and re-broadcast over the siren

speaker. Connect GREEN wire to a momentary switch before recording or re-playing

For Recording:

1. Enter the recording mode by pressing and holding the Record-n-Play switch for more than 5

seconds; a continuous single beep will sound from the siren speaker. Do not release the switch yet.

2. While holding the switch, pick up the microphone and press the PTT button to start recording. (DO

NOT release the switch or PTT during the recording.)

3. Release the PTT button to end the recording; double beeps will sound from the siren speakers.

Release the momentary switch to save and exit the process.

For Re-Play :

1. Quick press the Record-n-Play switch once to play the pre-recorded message three times.

2. Quick press the Record-n-Play switch 3 times to play the pre-recorded message continuously.

3. Quick press the Record-n-Play switch once during the re-play to end the re-broadcasting.
