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 congurations.
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.

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.

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.

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.

Connecting Trigger Devices
The WIR401 can be used
to control various trigger
devices. On the right are
a few examples on how
to wire the most common
trigger devices.
When trigger devices are
connected you will need
to set the latching mode as
explained below.
Latching Modes
The WIR401 has two Latching modes which control how
long the relay is active, Latching and Non-Latching.
Latching acts as an On/Off switch. When the transmitter
is pressed the relay will stay active until the transmitter is
pressed again.
Non-Latching mimics the press of the transmitter and will
only remain active as long as the transmitter is pressed.
(Not compatible with WIR305 key pads)
The Latching mode is set by the position of the Latching Cap
on the PCB. To position the Latching Cap you will need to
open the receiver.
First remove the front faceplate then remove the front of
the housing. There are 2 locking clips on either side of the
housing. To release the clips you will need to push on the
side of the front housing and lift at the same time.
Once removed you will see the black Latching Cap in the
middle of the PCB. To set the receiver to Latching mode the
Latching Cap needs ts across both pins (right top). To set
the receiver to Non-Latching mode you need to remove the
Latching Cap and reconnect it to one pin only (right bottom).

Latching Modes
The WIR404 has two Latching modes which control how
long the relay is active, Latching and Non-Latching.
Latching acts as an On/Off switch. When the transmitter
is pressed the relay will stay active until the transmitter is
pressed again.
Non-Latching mimics the press of the transmitter and will
only remain active as long as the transmitter is pressed.
(Not compatible with WIR305 key pads)
The Latching mode is set by the position of a dip switch on
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 .
Once removed you will see 4 dip switches on the top of
the PCB labelled 1 to 4. To set a channel to Latching ick
the corresponding dip switch to On. To set a channel to
Non-Latching ick the corresponding dip switch towards
the channel number.
Basic Operation
The 4ch receiver has 4 numbered push buttons on the
front of the unit so that the 4 relays can be controlled from
the receiver itself.
This makes it a great option for central locations such as a
reception desk or security offi ce where an operator could
control security barriers or an electronic door release to
grant access to visitors.
Members of sta would gain access as and when they
needed using key fob and key pad transmitters.
