System Operation
The Keypad has 13 control switches (1 – 13), 2 programmable switches (P1 & P2) and a Reset/Walk Test switch (14).
Pressing any switch will give a corresponding output from the Output/Receiver. i.e. SW1 will switch output 1 on the
Output/Receiver, SW2 output 2 etc. Switches 1-12 can be set to latching or momentary operation. Switches 13, P1 and
P2 are latching only. Switch 14 has preset functions and cannot be changed. Latching switches once pressed remain
active until pressed again; momentary switches are active only when pressed. A bank of switches can also be set as ‘self-
cancelling’, which means that only one switch in the bank can be active at any one time. Switch 14 will cancel all active
switches.
The keypad has a permanent backlight for low light viewing and each active latching switch is illuminated 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.
Walk Test
By pressing and holding down switch 14 for 4 secs, switches 1 – 13 will be made sequentially active to allow the operator
to confirm that both the system and the equipment that it is controlling are functioning. When running this facility, switch 1
will remain active for 10 seconds to allow the operator time to exit the vehicle; thereafter subsequent switches whether
latching or momentary will remain active for 4 seconds. (Latching switches will illuminate when active momentary switches
will illuminate briefly) Switch 14 will flash whilst the test is in progress. When the test is complete the keypad will
automatically reset.
Sleep/Wake Up Function
The system will automatically shut down (sleep) after approximately 1 hour if no channels are active and the supply
voltage is less than 13.5V. (i.e. the vehicle is not running) The system will ‘wake up’ when a switch is pressed, the voltage
exceeds 13.5V or the door is opened (if connected).
The system will not go to sleep if any channel is active, the voltage is
O
13.5V or if the ‘door switch’ sense is negative.
Audible and Visual Warnings
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 led will flash continuously when the battery voltage falls below 9.5V.
When the door and handbrake are connected to the Interface unit, if the door is opened when the handbrake is not
applied the system will sound a warning beep.
Automatic Arrival Switching
When the door and handbrake are connected to the Interface unit, and P1 (pursuit) is active, if the handbrake is applied
and the door is opened, the system will switch to P2 (arrival).
If this function is required the ‘External 999 Switching’ cannot be used.
External 999 Switching (This is not available on systems with ZE0169i1 keypads)
When required the door switch signal can be used to switch the system to the programmed switch P1.
If this function is required the ‘Automatic Arrival Switching’ cannot be used.
PA Microphone
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 side of the keypad. When the switch is operated it will mute any
active siren tones. The volume is factory set but may be adjusted to suit operator preferences. See
Figure 2
.
Mounting
A number of installation options are made possible through the availability of various fascia mounting brackets. The
Keypad can be positioned either vertically or horizontally allowing the best use of limited mounting space.
Default Programme
The keypad may be supplied with a default programme which does not give the desired control. To disable the
programme disable the lockout and press and hold SW11 and SW14 until a confirmation beep is heard. Enable the
lockout
