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 d
isplayed 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.
