Alarm - Connect the wire labeled ALARM to a circuit that can supply a +12VDC signal when activated. When a +12VDC signal is seen on this input,
a repetitive alarm will sound on the output speakers until the +12VDC signal is removed. For example, this can be used to alarm the police offi cer
when a temperature sensor on a K-9 unit has reached dangerous levels. The ALARM input will operate with the IGNITION input on or off.
Automatic Short Circuit Protection - The Z3 Siren will sense a short circuit on the speaker outputs and automatically go into standby until the fault
is removed. Once the fault is removed, the Z3 Siren will return to normal operation.
Power Up Self Test - When the Z3 Siren system is powered up with the vehicle ignition, it will test the communication between the Amplifi er and the
Control Head. If this test fails, the Control Head will blink all LEDs and beep until communication is established.
Instant On - There is no “ON/OFF” switch. If the Z3 Siren is properly installed and the vehicle’s ignition is switched on, selecting any siren function or
keying the microphone will activate the selected siren function.
Microphone - Push-To-Talk (PTT) is highest priority and overrides all other siren tones. Pressing the push-button on the microphone will
automatically override all siren tones and switch to the public address mode. The microphone is easily plugged into the Control Head with a modular
phone plug. This allows the microphone to be unplugged for easy service or replacement.
Stuck Mic - If the PTT is pressed for 30 seconds , the Z3 Siren will disable the PTT and return to the previous operation. This will avoid the situation
where the PTT is “stuck” in the one position for extended periods. To continue using the PTT, release the PTT and press it again.
Blown Fuse Indicator - The Z3 Siren will give a visual warning if there is no power being supplied to any 3-Level output or to the Auxiliary A through
F outputs. This can be caused by a loss of power to the Z3 Siren power harness or by a blown fuse in the Z3 Siren. If any 3-Level output has no
power, the 3-Level Switch LEDs will blink to indicate that there is a fault. If any of the Auxiliary A through F outputs has no power, all activated
Auxiliary A through F LEDs will blink to indicate that there is a fault. The fuses can be easily accessed through the top of the Z3 Siren.
