Designed to accept radio frequency (RF) calls from Quantec’s staff attack transmitters & patient pendants.
QT422RX receivers are designed to be internally mounted and provide up to 60m RF coverage in communal gardens, car parks, etc.
The optional QT422RXEX external mounting aerial can extend coverage to up to 90m.
A recommended Option the QT421 RF Integrity transmitter will send periodic test transmissions to a QT422RX receiver (we recommend at least one is used per receiver)
In large areas multiple radio receivers can be used to ensure sufficient coverage.
For sites with multiple, separately-manned areas, an RF Grouping facility allows different radio receivers to respond to calls from certain transmitters
