Chapter 3: Wiring the e-Q2B Siren System
e-Q2B Siren System
20
The siren can be controlled by the position of the five-position rotary switch located on the control
head. The five rotary switch positions are
OFF
,
MANUAL
,
WAIL
,
YELP
,
and
PRIORITY
. In addition,
the radio rebroadcast function is available while the
MANUAL
mode of operation is selected and the
RADIO
button is activated.
If the
MANUAL
position is selected, the siren can be manually activated by pressing the
CYCLE
or
BRAKE
push buttons or foot switches (if installed). By activating the
CYCLE
button, the siren
tone increases in frequency. By releasing the
CYCLE
button, the siren tone gradually decreases in
frequency. The activation of the
CYCLE
switch simulates the application of voltage to the original
electromechanical Q siren. Releasing the
CYCLE
button simulates the coasting down of the original
electromechanical Q siren.
The activation of the
BRAKE
button simulates the accelerated braking, or slowing down, of the
siren output. This braking action is similar to the original electromechanical Q siren when the brake
solenoid is activated.
The
AIR HORN
function is selectable anytime the rotary switch is not in the off position. The
AIR HORN
tone sounds with all other siren tones:
MANUAL
,
CYCLE
,
BRAKE
,
WAIL
,
YELP,
and
PRIORITY
. The microphone via its push-to-talk switch or the PA/radio rebroadcast function
overrides the
AIR HORN
function.
Connecting the Switch Input for the Model e-Q2B-200-RCFD
The Model e-Q2B-200-RCFD siren is designed to operate without a control head. The siren
produces a continuous e-Q wail tone while the
CYCLE
input is activated. The foot switch input is
connected to the front of the siren amplifier through the 2 x 6 plug-in terminal block. The
CYCLE
input is the only active input on this model. No other features are available.
The power connections are the same as those for the standard e-Q siren. Connecting the
CYCLE
input to ground through a switch generates a siren tone. Immediately disconnecting the switch turns
off the siren.
