Another feature allows cycling through Wail, Yelp, Phaser and Standby by
providing a signal to the horn ring auxiliary wire when the function switch is in
the Hands Free (HF) position. A Park Kill option is provided for connection to a
door switch, etc. to disable the siren when exiting the vehicle. The PA volume
control is provided on the front panel of the control head, while the Radio volume
is on the amplifier box. The front panel is backlighted with LED’s for night
visibility. This compact unit utilizes short circuit, high voltage, low voltage, and
reverse polarity protection systems for maximum service life.
The SS741MG unit is designed to allow maximum versatility in mounting.
The control head is remote from the siren amplifier box creating a compact user
interface plate that can be flush mounted into the dashboard. The amplifier box
can then be mounted remotely in the trunk, under the dashboard, under the seat,
or wherever convenient.
The siren amplifier has been designed with several protection features to
provide exceptional field service. Excessively high or low voltage detection will
disable the siren output to protect both the amplifier and the speaker. Fused inputs
provide safety against reverse polarity. Speaker diagnostics provides user
feedback as well as shutdown protection if the speaker output becomes either
electrically open or shorted. The two separate independent amplifiers allow
redundancy backup, should one speaker short out during operation the other
amplifier and speaker will remain fully operational. CAUTION: These
protection features will not guard against overloading the outputs.
The SS741MG unit is available in the following different versions:
SS741MG Standard version w/ microphone mounted to the face
plate.
SS741MGX Remote microphone connected to the back of the control
head via an extension harness.
SS741MG-TEC Standard Version with reversed 7-position knob functions.
