LE80 Radio Receiver

Multipurpose LE80 Radio Receiver

With its multi-purpose operating modes, the LE80 Radio Receiver can be used in combination with wired or wireless Nurse Call systems. It is designed to receive radio signals from different TeleAlarm radio transmitters at the frequency of 868.8MHz. When receiving radio signals from either programmed or non-programmed wireless transmitters, the LE80 Radio Receiver switches its two relay outputs and activates its two LED indicators, according to the different functional modes described below.

The LE80 can be powered by 6-30VDC or by the optional power supply unit.

Nine different operating modes

868.8 MHz bidirectional

Functions

The LE80 Radio Receiver can be set to one of nine different operating modes in which the device behaves according to different transmitter inputs. Operating mode setup can only be done using the PR80 programming unit. Transmitters can be programmed with or without the PR80.

Mode 1: Normal (default mode)

Up to twenty wireless transmitters can be programmed. Calls are indicated by LED 2 and Relay 1. A low battery signal is indicated by LED 2 and Relay 2. Additionally, the custom output (see pinout) provides predefined voltages for four different predefined calls.

Mode 2: LED 2 deactivated at low battery indication

Function is the same as in Mode 1, except the low battery signal is indicated only by Relay 2. Additionally, the custom output (see pinout) provides predefined voltages for four different predefined calls.

Mode 3: Dementia

S87L and B80A wireless transmitters can be detected. Relay 1 can be used to lock a monitored door. Relay 2 can be used to trigger an existing Nurse Call system, or an input for other monitoring devices.

Mode 4: Dementia with Accompany

The LE80 Radio Receiver can be connected to a wired Nurse Call system, in which the ‘Accompany’ function can be implemented. Here the LE80 Radio Receiver will wait 10 seconds after receiving a signal from an S87L transmitter. If it detects a B80A transmitter

in this time window, then no alarm is generated. If not, then Relay 1 is activated for 2 seconds.

Mode 5: Remote control

Up to 20 wireless transmitters can be programmed. Per sequence, only the same transmitter can switch Relay 1 on and off.

Mode 6: Open receiver

No wireless transmitter needs to be programmed. Any transmitter within reception range of the LE80 Radio Receiver will activate the device.

Mode 7: Open receiver with a door location beacon number

Same functions as in Mode 6, but with door position transmission. Any transmitter within reception range of the LE80 Radio Receiver will activate the device, but only if the LE80 receives a signal (with the exception of a dementia) which contains the door beacon number.

Mode 8: Unique N86 behaviour

Behaviour is similar to normal Mode 1, with certain differences according to the transmitter or call type that is activated. Triggering an alarm on a programmed N86 transmitter will activate the Relay 1 for max. 20 min. The 20 min. cycle can be interrupted by the acknowledgement function of the same N86.

Mode 9: Dual channel receiver

All TeleAlarm Nurse Call alarm transmitters can be programmed. Calls are indicated by Relay 1 or Relay 2, according to the slot where the wireless transmitters are programmed. A low battery signal is indicated by LED 2.
