This transmitter is supplied as a self contained PCB assembly for installation into
other equipment. This unit will transmit to all the 4600 series receivers. (Refer to
modes of operation for correct use.) It has an integral, unique design, mini-helical
aerial that attaches directly to the PCB: alternatively, it can be used with any
external, 50 ohm aerial, if required.
Design advantages include:
• Crystal controlled accuracy
• Pulse scanning of inputs increases immunity to damp conditions
• Built in long-life lithium battery. (seven year target lifetime.)
• 12 functional modes cover most requirements
PHYSICAL DETAILS
The unit consists of a single-sided, SMT technology PCB,
90mm x 63mm, which incorporates a standard 4600 series encoder and a
Scantronic 04689UK-50 transmitter. There are three types of input terminals, each
with a positive (+ ve), Ground (Gnd) and an input connection (A,B,C) for
convenience.
Two groups of DIL switches are provided, one group of 12 controls the site/unit
code settings and the smaller group of 6 control the operating modes.
The aerial connection takes a 6BA, or similar, nut/bolt enabling the small, spring,
helical aerial supplied to be fitted directly to the PCB, or, if required, a flying lead to
any external aerial can also be used.
The 04603UK-50 is powered by a permanently-connected 3.7V Lithium-thionyl
chloride power cell. The PCB consumes a small amount of current, even when not
transmitting, giving a quiescent battery life of sixteen years for slow mode and
seven years for fast mode operation. If the transmitter is triggered 50 times a day,
the theoretical battery life is reduced to 10 years and 6 years respectively.
Scantronic specify 7 years and 4 years to allow for tolerances.
In test mode, the battery consumption is typically 5mA giving a continuous
transmission time of 320 hours.

GENERAL DATA
Some background data on the 4600 series signalling format will help you
understand the more complex functions. The code sent by the transmitter is a 12 bit
data frame repeated for approximately 1.5 seconds. To indicate a low battery, the
transmission time is extended to approx. 7 seconds. These 12 bits can be used for
different functions according to the application.
They are split as follows:
The first x bits are site (or house) code.
The next y bits are unit (or zone) code.
The last z bits are data bits, by convention, they are
lettered, in order, DCBA (Max 4 bits only)
For example, the 4600 radio alarm panel has 6 site code, 4 zone code and 2 data
bits.
FUNCTIONAL MODES
Before attempting to use any new mode, refer to the operational notes at the end
of this document.
The unit has many different operational modes selected by the DIL switches and
control input C. It also has an input speed selection DIL switch (FAST).
The main modes are:
1. Single channel, A input, low to trigger.
2. Single channel, A input, bi-directional to trigger (A inverted).
3. Boat/caravan, single zone panel + transmitter, with built-in delay timer.
4. Alarm/tamper with restore on both alarm and tamper.
5. 2 channel, bi-directional trigger on both A and B inputs.
6. Two channel, bi-directional trigger only on B input.
7. Two channel, with B input configured for tilt switch. `includes built-in delay
timer and pre-transmit warning
bleep.
8. Four channel mode. Four button capability but will send only the first button
pressed. ( multi-key lockout.)
9. Four button/two channel mode. Two pairs of buttons turn on/off '9' internal
memories in the transmitter. Only if a change in a memory has occurred will a
transmission be sent. (Nursecall mode.)
10. Two button/two channel mode. Sends both buttons as they are pressed
(either together or separately).
11. Self-test. Sends the 12 DIL switch code, regardless of the operational mode.
In all modes at the end of a transmission, the 12 site/unit code DIL switches are
scanned and remembered by the unit. When the transmitter is next activated it uses
that data for the new transmission. Not all the 12 bits will be used; depending on
which mode is used, up to 4 data bits are altered according to the input states.
HOW TO SELECT A MODE.
1. Single channel, mode 'A' trigger, for 4611, 4612, 4613, 4618/9 & 4660/75
transmitters.
'MODE O' and 'MODE 1' DIL switches must be ON. Inputs B and C
must not be connected.

If a connection is made from input A to Gnd, the transmitter will send 12 site/unit
code bits read directly from the DIL switches. No transmission will occur when the
connection is removed.
2. Single Channel, 'A' Input, bi-directional to trigger
('A' Inverted) for 4611, 4612, 4613, 4618/9, & 4660/75 transmitters.
MODE 0' and 'MODE 1' DIL switches must be ON.
Input B must not be connected and input C must be tied to Gnd with a wire
link.
If input A is either connected to, or disconnected from Gnd, the transmitter will
send 11 site/unit code bits read directly from DIL switches with data bit A (the 12th
data bit) active (logic 1) if the link is made, or in-active if the link was removed, i.e.
it sends the status of the A input on data bit A, but inverted.
3. Boat/caravan single zone panel for 4612, 4618/9
& 4660/75 transmitters.
'MODE 0' DIL switch OFF.'Mode 1' DIL switch ON. Connect an arming
switch (key switch or similar) across input C to =ve. Connect a normally
closed sensing device between input A and Gnd.
Panel is disarmed with the key switch ON. Input B is continuously monitored (24
hour tamper zone).
If it opens, the transmitter will send 10 site code bits together with data bit B active
and data bit A as per input A (i.e. input A linked to ground will give data bit A
inactive). Any activity on input A is otherwise ignored whilst the unit is disarmed.
If the key switch is opened, the panel goes into a fixed 25 second exit period during
which the bleeper sounds.
At the end of this period, the bleeper goes quiet and input A becomes armed. If
input A is now opened, the 25 second entry period starts, together with the
bleeper. If the panel is not disarmed, by closing the keyswitch during this period,
the transmitter will send 10 site code bits together with data bit A active. When the
transmission ends, input A will be re-armed.
The panel can be disarmed at any time by closing the key switch.
4. Alarm/tamper transmission, with restore on both alarm and tamper. 4612,
4618/9, 4660/75 & 4600.
'MODE 0' DIL switch OFF, 'MODE 1' DIL switch ON. Input C linked to Gnd.
Connect a normally closed tamper loop between input B and +ve. Connect a
normally closed sensing loop between input A and Gnd.
If either input A or input B loops are broken or reconnected, a transmission will be
triggered. It will send 10 site/unit code data bits read directly from the DIL switches
DIL switch together with the state of the A and B inputs. The A & B data bits are
inactive (logic 0) if both input 5 loops are intact.

5. Two channel with bi-directional trigger on both A & B inputs. 4612, 4618/9
& 4660/75.
'MODE 0' DIL switch ON. 'MODE 1' DIL switch OFF. Input C linked to +ve.
Connect as 4 except that the loop on input B is from Gnd to input B.)
6. Two channel with bi-directional trigger only on B input.
4612, 4618/9 & 4660/75.
'MODE 0' DIL switch 'ON' and 'MODE 1' DIL switch OFF. Input C must be
disconnected.
If input A is linked to Gnd or Input B is connected to/or removed from Gnd, the
transmission is triggered. It will send ten site/unit code data bits read directly from
the DIL switches plus the state of the A & B inputs. If the inputs are connected to
Gnd at the time of transmission, the data bits A & B will be active (logic 1).
7. Two channel with B Input configured for tilt switch.
4612, 4618/9 & 4660/75.
'MODE 0' DIL switch 'ON' and 'MODE 1' DIL switch OFF. Input C must be
connected to Gnd.
Connect a push-button from input A to Gnd and a normally closed mercury tilt
switch from input B to Gnd.
If the button is pushed, an immediate transmission is sent with data bit A active
(logic 1). If the mercury switch contact opens, an internal timer starts to run. If the
contact remains open for 14 seconds, the buzzer starts sounding. If the contact
remains open for a further 14 seconds, a transmission is triggered with data bit B
active (logic 1). The mercury switch closing at any time before the transmission,
resets the timer to zero and silences the bleeper. If a B type transmission has been
sent, closing the mercury switch contacts triggers another transmission with both A
& B data bits set inactive (logic 0). This is effectively a 'restore ' transmission. In all
the transmission types, the first 10 data bits are site/unit code read direct from the
DIL switches.
8. Four channel mode. Four buttons. 4618/9.
Both 'MODE 0' and 'MODE 1' switches OFF. Input C must be linked to +ve
Up to 4 normally open push buttons can be connected as follows:-
Button D from input A to Gnd
Button C from input A to +ve
Button B from input B to Gnd
Button A from input B to +ve
Pressing any button sends transmission that consists of 8 site/unit code bits read
direct from the DIL switches together with 4 data bits DCBA. Only one data bit is
active (logic 1) according to which button was pressed.
9. Four button/two channel mode. 4618/9 & 4660/75
Both 'MODE 0' and 'MODE 1 switches OFF.` Input C must be disconnected.
Four buttons can be connected as per 8 above.
The transmission consists of 10 site/unit code bits read directly from the DIL
switches together with two b its held in internal A & B memories. The B memory is
turned ON' (active) by pressing button A and 'OFF' by pressing button B. The A

memory is turned 'ON' by pressing button C and 'OFF' by pressing button D.
The new transmission will only occur if either memory has changed since the last
transmission.
If buttons B & D are replaced by two diodes and one button (B), the option
functions as a nursecall with button B being the cancel button.
10 Two button/two channel mode.
Both 'MODE 0' and 'MODE 1' switches OFF. Input C must be linked to Gnd.
Two buttons can be connected - button B from input B to +ve and button A from
input A to +ve.
This functions similarly to 9 above except that the memories are automatically
turned 'OFF' at the end of a transmission.
11 Self test mode.
This mode is selected by separate DIL switch labelled 'TEST'.
If selected, it overrides any other mode selection and repeatedly sends a
transmission, consisting of 12 site/unit code bits read directly and continuously from
the DIL switches. Changing the DIL switches during the transmission will cause an
immediate change in the transmitted data.
FAST MODE OPERATION
The DIL switch labelled FAST gives two options for the speed at which the inputs
are scanned which also has a direct affect on battery life.
If the FAST switch is off, the inputs are scanned every 100mS. This is suitable for
most types of input except very fast push buttons and gives battery life of typically
7 years. If the FAST switch is 'ON' the inputs are scanned every 20mS, with a
reduced battery life of typically 4 years.
If the speed mode is changed, it is necessary to switch off the transmitter and wait
2-3 seconds before switching on again, before the new speed comes into effect.
OTHER OPERATIONAL DATA
a. In all operational modes except 7, the bleeper will produce a small click every
time any input (A, B or C) changes state.
b. If any DIL switch is changed, the first transmission immediately after the
change will use the old switch data.
Always 'throw away' the transmission following a DIL switch change.
c. Most modes of operation will not allow a second transmission of the same
type as its predecessor within 500ms. This is to avoid several transmissions of
the same type causing a false 'low battery' signal at the receiver.
d. Switching on/off.
The DIL switch labelled ON/OFF isolates the battery. It takes up to 15
seconds for the circuit to correctly function after switching on.
