Quantec’s QT412 transmitters allow users to activate calls on a Quantec system. They have a typical
infrared (IR) transmitting range of 10 metres (line of sight) and a typical radio frequency (RF)
transmitting range of approx. 60 metres, dependent on physical conditions / environmental factors.
Each transmitter has two IR emitter
windows (one on each side to maximise
performance), two buttons (A & B) and a
retained ‘pull clip’.
Depending on the model purchased,
pressing its buttons, or activating its pull
clip, will generate the following levels of
call on compatible Quantec IR call points, IR
ceiling receivers and/or RF receivers.

Note that different levels of call to those listed above can be generated, if required. However, to
do this the transmitter must be reconfigured by an experienced engineer using a QT423
Configurator (see page 4 for details). Note these instructions explain how to use standard factory-
supplied QT412RXA and QT412RXCA transmitters only.

RECONFIGURING THE TRANSMITTER (OPTIONAL)
The QT423 Configurator allows the operation of a QT412 range transmitter to be tailored to suit
the requirements of a specific site. It allows authorised engineers to:
(Note: The available level of calls available include Attendance, Standard Call, Presence, Help
Required, Reset, Emergency and Attack. See
COMPATIBILITY ISSUES
, below.)
• Assign the level of call that will be triggered when the transmitter’s A button is pressed
• Assign the level of call that will be triggered when the transmitter’s B button is pressed.
• Assign the level of call that will be triggered when the transmitter’s pull clip is activated.
• Set the transmitter’s A & B buttons so they only trigger a call when both are pressed at the same time.
• Turn the transmitter’s ‘confidence’ beeper on or off (for button A, B and/or the transmitter’s pull clip).
• Turn the transmitter’s RF action on or off (for button A, B and/or the transmitter’s pull clip).
• Set the transmitter’s transmission time to run continuously or to automatically switch off after
a pre-determined time.
• Set the transmitter’s User ID code (from 0 to 255). See
COMPATIBILITY ISSUES
, below.
• Assign the transmitter an RF Group Address (0 to 15) to match the set up of any Quantec RF
receivers on the system and prevent inadvertent triggering of any local receivers.
• Change the transmitter’s mode of IR transmission to ‘pulsed’ to suit Quantec IR receivers
manufactured before 1/10/99 (see
COMPATIBILITY ISSUES
, below).
