Introduction
The Zendit range of wireless key fobs & key pads is a gift to any CCTV, alarm or access
control engineer thanks to its versatility and wide range of congurations.
Ideal for opening gates, switching lights on, sounding audio devices such as the VoiceO,
this great value range adds lots of functionality to a security or automation system
without a hefty price tag.
The key fobs can be used as a standard fob for up to 4 devices or even wall mounted in a
bracket to serve as a static panic button or controller. Handy belt clips are also available
to carry the fobs on your person within easy reach again as either a panic button or for a
member of sta to gain quick control or access of other equipment.
The entire range includes single or multi (2, 3 or 4) button key fobs in either a white or
black nish with a selection of key-rings and clips, compact wall mount push button key
pads and 1 or 4 channel receivers with control buttons too.
Dual channel key pads are a useful addition to the range allowing a xed access pad to
activate the opening of a door or gate without the risk of personnel losing or forgetting
their keys.

Wireless Key Fobs
The Zendit key fobs oer an eective, low cost method for
wireless control of up to 4 electronic devices.
1, 2, 3 and 4 channel fobs are available in black and white. The
small compact fobs have a working range of up to 50m and a
handy sliding button guard prevents accidental activation.
This section explains the simple steps required for pairing
key fobs to receivers, learning commands, replacing
batteries and operation.

Pairing Key fobs & Receivers
It’s really easy to pair a key fob with a receiver, just follow
these 2 simple steps:
Step 1
Press the Learn button on the receiver. The LED light on
the front of the unit will turn red.
For the 1Ch WIR401 this is found on the side of the unit.
On the 4Ch WIR404 it is positioned at the top of the PCB.
To gain access you will rst need to remove the cover by
unscrewing the small locking screws on either side of the
unit. The front panel can then slide up and o.
Step 2
Press Button 1 on the key fob Twice. The LED light on the
receiver will ash and then turn o.
Note: When pairing a multi channel key fob all other
channels are learnt automatically after learning
channel 1. Channel 1 activates relay 1, channel 2
activates relay 2 and so on.

Wireless Key Fobs
Self Learning
The Self Learning function (On the 2, 3 & 4 channel key fobs) allows you to copy
commands from one key fob to another. Self Learning is an easy way to set up multiple
key fobs or add new key fobs without having to go back to the receiver.
To program a key fob using Self Learning follow the 3 steps below:
Replacing A Battery
The key fobs are powered by a CR2032 3V DC battery
which should last for up to 2 years of general use. Don’t
worry, when the battery does run out you won’t need to
pair the key fob again, just replace the battery.
To replace the battery you will rst need to remove the
three small screws from the back of the key fob (shown
right). Remove the back of the housing to reveal the
battery. Slide the battery out of its holding slot and
replace with a new one ensuring the new battery is
installed with the positive side facing up.
Useful Accessories
Wall mount brackets allow key fobs to serve as a static
panic button or controller.
Handy belt clips are also available to carry the fobs on
your person within easy reach again as either a panic
button or for quick control or access of other equipment.
Step 1
On the Existing key fob press
Buttons 1 and 2 together.
Step 2
Now press Button 2.
Step 3
Now on the New key fob
press Button 1 Twice.

Wireless Key Pads
Our dual channel key pads can be used to create a xed
access pad ideal for opening doors and gates eliminating
the risk of losing or forgetting keys.
Relays are activated by entering a numeric password
rather than the press of a single button for a secure
wireless solution.
This section explains the simple steps required for
installation, pairing key pads to receivers, operation,
password management and battery replacement.
Specication
Frequency Range Battery Dimensions
433.92MHz Up to 100m 3V CR2450 93 x 73 x 43mm
Installation
As an anti-tamper measure key pads can only be installed
and removed using one of the keys supplied:
Step 1
Insert the key into the lock on the underside of the key
pad. Turn the key clockwise until it clicks and then lift the
front of the key pad o the mounting plate.
Step 2
There are ve mounting indented knock-out holes for
securing the key pad. Either use a hammer and punch
or drill out the holes required. You can choose to use 3
screws in holes 2, 4 & 5 or 4 screws in holes 1, 3, 4 & 5.
Step 3
Mark the screw positions on the mounting surface, drill
the holes and plug with appropriate xings.
Step 4
Screw through the holes in the key pad’s base and into the plugs.

Password Management
Zendit password controlled key pads provide extra security
as they restrict access and control to chosen personnel.
You can even set dierent passwords for each channel.
The section below has simple steps on changing and
resetting passwords.
Default Password
The default password for both channels is 000000.
Changing The Password For Channel 1
•Hold down Button A until the top left LED lights up.
•Enter current password e.g. 000000 and press Button A.
The second LED will then light up.
• Enter your new password e.g. 123456 and press Button A.
The third LED will then light up.
•Re-enter your new password e.g. 123456 and press
Button A. The rst three LEDs will then ash to conrm
your new password has been set.
Changing The Password For Channel 2
•Hold down Button B until the top right LED lights up.
•Enter current password e.g. 000000 and press Button B.
The third LED will then light up.
• Enter your new password e.g. 123456 and press Button B.
The second LED will then light up.
•Re-enter your new password e.g. 123456 and press
Button B. The last three LEDs will then ash to conrm
your new password has been set.

Resetting The Password
•Insert the key into the lock on the underside of the key
pad. Turn the key clockwise until it clicks and then lift
the front of the key pad o the mounting plate.
•Press and hold any numeric button so that the second
LED lights up.
•Keep holding the button, with the other hand turn the
battery cover clockwise and remove. Re-insert and turn
anti-clockwise to lock in place. All 4 LEDs will then light
and go out one by one from the right. The password will
now be reset to default 000000.
Battery Maintenance
The key pads are powered by a CR2450 3V DC battery
which should last for up to 2 years of general use. Don’t
worry, when the battery does run out you won’t need to
pair the key pad again, just replace the battery.
Note: To replace the battery you will need to use one of the
keys supplied with the key pad.
Low Battery Indicator
If the battery voltage is lower than 2.4V the two centre LEDs
will light together when pressing any numeric button as a
reminder to the user that the battery requires replacement.
Replacing A Battery
•Insert the key into the lock on the underside of the key
pad. Turn the key clockwise until it clicks and then lift
the front of the key pad o the mounting plate.
•Turn the battery cover clockwise and remove.
•Slide the battery out of the holding clips and replace
with a new battery ensuring the negative side of the
battery is left exposed.
•Re-insert and turn anti-clockwise to lock in place.

1Ch Wireless Receiver
The compact 1Ch receiver is perfect for smaller systems. For
extra security the WIR401 uses rolling codes which change on
every use, this means they are never duplicated.
Specication
Feature Specication
Working Voltage 12V DC 30mA
Temperature Range -20ºC ~ +60ºC
Frequency 433.92MHz
Max Stored Transmitters 30
Relay Load Capacity 1A 30V DC
Weight 36g
Dimensions 58 x 34 x 20mm
Installation
To mount the lightweight receiver we recommend a
simple double-sided adhesive foam pad.
Connections & Powering
All connections to the WIR401 are made using the screw
terminals at the bottom of the receiver. This can be done
without opening the case. Removing the front faceplate
exposes the screw terminals and the wires can be inserted
into the holes in the bottom of the case (right top).
There are 5 screw terminals (right bottom). The rst 2 from
the left are for connecting the power. These terminals
are not polarity sensitive so the 12V DC and the Ground
(GND) can be connected to either terminal. The receiver
requires 12V DC power source supplying at least 30mA.
The last 3 terminals are for the relay. From left to right they
are Normally Closed (NC), Common (COM) and Normally
Open (NO). The relay is limited to 30V DC and rated at 1A.
When connecting a trigger device to the receiver you
will also need to set latching mode as explained on the
opposite page.
