999 / Arrival / Reset Switch
The Keypad has 12 standard control switches, 1 siren control switch and a 999/arrival/reset switch. Pressing any standard switch will
give a corresponding output from the Output/Receiver. i.e. SW1 will switch channel 1 on the Output/Receiver, SW2 channel 2 etc. The
siren switch operates channel 13. Switches 1-12 can be set to latching or momentary operation. Switch 1 and 2 are intended to be
used as a light bar front/rear/360 utility as detailed below. The siren switch is only latching. Latching switches once pressed remain
active until pressed again; momentary switches are active only when pressed.
Switches 1 and 2 are assigned for use with a light bar. Switch 1 activates the front of the light bar and switch 2 the rear. When both
switches are clear, hold switch 1 for 0.5 seconds and it will activate both channel 1 and 2 giving the user a 360 function with one
button press. When in 360 mode, hold switch 1 for 0.5 seconds and the keypad will de-activate both channels 1 and 2. The buttons
operate as normal in all other situations.
A bank of switches can also be set as ‘self-cancelling’, which means that only one button in the bank can be active at any one time. The
keypad has a permanent backlight for low light viewing and each active latching switch is illuminated further when active. Momentary
switches are illuminated only when pressed. Under low light conditions a light sensor will lower the illumination intensity of all active
switches to prevent driver distraction. The sensor for this is situated at the bottom of the keypad and should not be covered if the
Auto Dim feature is to function. Keypad legends can be factory fitted according to the customer’s requirements or customer fitted.
Soft switching prevents large current surges on the vehicle electrical system by staggering the programmed switch activation.
When the battery supply falls below 12 volts, providing no channels are selected, the power down timer will start up. After 20 minutes
the unit will power down and disable the keys back lighting. The unit will ‘wake up’ when a key is pressed or when the battery voltage
rises above 13 volts.
When the unit is asleep, pressing any key will wake the unit up but won’t turn that channel on. This allows the acts of waking and
operating a channel a separate action. The 999/arrival/reset key will however wake the unit up and activate the pre-programmed
respond mode, allowing a quick response if required.
If the battery is at or below 12 volts, pressing and holding the reset and siren keys together will put the unit to sleep. If the voltage is
too high, the unit will emit a long beep indicating to the user that the switch panel system can’t go to sleep.
The Keypad incorporates a public address microphone for use with a Woodway siren with PA capability and is made active via a PTT
(Press-To-Talk) switch located on the right hand side of the keypad. When the switch is operated it will mute any active siren tones.
The volume is factory set to 50% but may be adjusted to suit operator preferences via the keypad.
As a reminder that the panel is active, the LED at the top of the panel will flash and the system will beep every 30 seconds.

The 999/arrival/reset switch will automatically change its function between three modes of operation:
• Reset; when a key is selected manually or via the arrival button, pressing this key will clear any selected channels.
•
999; when the keypad is clear, pressing this button will activate the pursuit channels. A blue LED will light below the button to
indicate this mode is active.
•
Arrival; when the keypad is in pursuit (999) mode, pressing this button moves the selection to the preset arrival mode. A red LED
will light to indicate that the keypad is in arrival mode. Pressing the button again will clear all channels (reset).
•
Walk test; holding the 999/arrival/reset button for two seconds will activate an automatic walk test. This will turn on each channel
consecutively for five seconds allowing the user to check the operation of each device on the system. The first channel will stay lit
for fifteen seconds to allow the user time to exit the vehicle. Press the reset button to cancel the walk test at any time.
