System Overview
The 1142RX Radio Receiver
This system is be set to operate on ‘Cancel at
Source’.
The systems operating radio frequency is 868MHz.
The 1142 unit is 240 Volt mains powered with an
internal stand by battery.
It is advisable not to place the radio receiver close
to metal filing cabinets or at a low level. The higher
the 1142RX portable receiver is above the floor level
the better the radio reception. Do not place the
receiver next to computers or similar equipment
that emit spurious radio signals.
The range of the Call Aid UK radio transmitters is approximately 80 metres indoors, depending
on the building structure and up to 200 Metres outdoors. The range should be tested using the
1142’s RSSI (Radio Signal Strength Indicator) function at the proposed 1142RX portable position
in order to check that the radio Call alert buttons can transmit to the 1142RX receiver.
1142RX Incoming Alerts
When a call button is pressed the 1142RX display panel will respond by showing the call unit
identity in the OLED display. An audible alert will be activated, which will vary depending on
the alert type i.e. Call & Panic or Call & Assist.
If there is more than one Call alert on the system, the 1142RX display will scroll through the
incoming calls.
If “System Clear” is not displayed the power supply to the 1142RX unit should be checked.
Low Battery Warning
When a Call alert button is pressed and the battery is low, a low battery signal will be sent to the
1142RX master panel and the display will show “Low Battery” along with the Call alert button ID.
The “Low Battery” message can only be removed by changing the battery in the Call alert
button with the low battery and then sending a Call alert signal to the 1142RX master.
To Cancel/Reset Alerts
Call alerts can only be cancelled at the source of the call (i.e. at the radio Call alert unit that
transmitted the call). Alerts are cancelled at the triggered Call alert button with a double
button press function for units with two buttons.

on the 1142RX master. The higher the better but a minimum of 55 is recommended to give a
reliable signal. To cancel each call press both buttons at the same time on the transmitter unit.
Repeat this process until all the units have been tested. There is no need to action anything at
the 1142RX master as each time a Call alert button is tested it updates the RSSI value.
It is sensible to keep a record of this test so that should there be difficulties with receiving signals
from all the units above the 55 RSSI value you will able to “Map” how the signal is propagating
through the building.
If you cannot setup the system due to low signals please contact Call Aid UK on 0115 940 0905
for technical assistance.

Opening the 1150 Case
Battery:CR123
When the low battery signal is received at the master the battery will
have to be changed to stop the low battery beep.
Please ensure that the battery is installed correctly with the + to the +
symbol on the PCB.
Installation
Please note: This 1150 radio panic button should be located away from large metal objects as this will reduce the range of
the transmitter.Test that the signal is being received before final fixing. Hold the unit in the proposed position and test by
putting a call to the radio receiver.Try not to cover the 1150 with the hand as this will adversely affect the range
Low Battery
Setting room numbers
The numbers on the right hand side of the headers are binary numbers. To set the correct room number the numbers on the PCB
need to be added together. So by putting a jumper link on the numbered headers the appropriate transmit number is selected.
Please note: Unless by previous arrangement, units are shipped from our manufacturing dept. with the header links fitted to one
half of a header so that the unit does not have a pre-set number.
Example For room number 6= header 4&2should have headers fitted.
For room number 7= header 4&2&1should have headers fitted.
All the equipment fitted on any system must have the same system ID. All units are shipped from our manufacturing dept. with
the same System ID. To change the System ID on a transmitter unit the headers on J2 need to be moved. The headers relating to
the System ID are marked with S1, S2 and S4 on the right hand side. The numbers are binary numbers and so to get the correct
System ID the numbers selected with the jumpers need adding together as described above.
Example: System ID 3= header S2 + header S1. If there are no Jumpers on the System ID headers then the default setting
is System ID 1
To change the room number that will be
transmitted to the Radio Receiver the headers on
J1 need to be fitted to the correct position.

Setting the ID of the 1124
If the ID’s of the 1124 are known in advance then the numbering of the ID’s will be
completed during manufacture. However these are easily changed by moving the
headers on he PCB as shown below.
Each 1124 unit has a dedicated
ID number. To change the ID
number add or remove headers
to the required links.
E.G. Headers fitted to

1123-IP65 Radio Stand Alone Repeater
On the reverse of the 1123-IP65 Repeater there are few place for making holes that will allow
the repeater unit to be screwed onto the wall.
Before the repeater is screwed to the wall, test that all the Call alert button signals are reaching
the 1123 Repeater in the position on the wall where it is to be used. It is better for the repeater
to be as high as possible as the signal reception is better at this height.

further action is required, unless more panic buttons need to be stored, then exit the setup or
allow it to time out.
If there are five panic buttons already stored then the two left hand lamps will be lit until exiting
the setup.
To clear stored devices
If the 1123 memory is full (there are already five paired units in the memory) the two right hand
red lamps will be permanently lit when in setup mode. When more units need to be paired to
replace some of those already paired, the memory needs to be cleared. ALL the units to be
paired to this unit will need to be installed/reinstalled. When entering more devices and the
memory becomes full the two right hand red lamps will again be permanently lit.
