OVERVIEW & OPERATION
This transmitter allows you to take advantage of Quantec’s optional staff attack facility and
operates as follows:
• Designated staff attach the transmitter to their
uniforms using the Karabiner clip (supplied).
• In the event of an attack, staff activate the
transmitter by releasing its retained pull clip
(QT412RXA and QT412RXCA models) or by
pressing and holding one of its buttons
(QT412RXA models only). This will fill the area
with IR and RF signals - see illustrations, right.
• Upon activation, the transmitter sounds a short
‘confidence’ beep and its LEDs illuminate green
for approximately half a second to confirm that
an attack call is being transmitted. Note that a
different sequence of beeps and LED indication
indicates that the transmitter needs recharging -
see TRANSMITTER BATTERY, page 3 for further
details.
• The IR and RF signals generated by the transmitter are picked up by any Quantec IR call
points, IR ceiling receivers and/or RF receivers within its range which inform Quantec that an
attack is taking place.
• An urgent, piercing alarm is sounded throughout the building (as programmed) and the
exact location of the attack is indicated at all relevant displays to facilitate the quick response
of security staff.
Note that in addition to being able to generate an attack call via its retained pull clip, the
QT412RXCA transmitter will generate a standard call when either of its two buttons are
pressed. Standard calls are transmitted to compatible IR and RF receivers in exactly the same
way as attack calls and are reported around the Quantec system as programmed.
For security reasons attack calls can only be reset by entering a special code at the Quantec
Controller or a Display with controls. Refer to the Quantec Main Manual for details.
IR / RF TRANSMISSION TIMES
Calls triggered from either of the transmitter’s buttons will transmit for a maximum of 45
seconds (IR) and 30 seconds (RF) whilst pressed and for 2-3 seconds after release.
Calls triggered via the transmitter’s pull clip will transmit for a maximum of 45 seconds (IR)
and 30 seconds (RF) and for 2-3 seconds after it has been returned to its retained position.
The transmitter will sound a short confidence beep once every 3 seconds throughout its
IR/RF transmission period and its LEDs will flash green. When the transmission period is
complete, the transmitter will sound three quick beeps and its LEDs will flash red three
times in quick succession to confirm it has returned to its normal state.
Please note you will be unable to make a new attack call until the transmitter’s pull clip has
been returned to its retained position (the transmitter’s button operation will be unaffected).
RESETTING THE TRANSMITTER’S PULL CLIP
To return the transmitter’s pull clip to its retained position, gently
push its two outer prongs inwards until the mechanism snaps back
into place, as shown in the diagram, right.
TRANSMITTER BATTERY
The transmitter’s battery is rechargeable (NiMH). If left for extended periods, or after periods
of heavy usage without recharge, the battery may run flat. If this happens charge the unit
immediately for the full recharge period (see below). Please note that the battery is not a
user serviceable part and must be returned to your Distributor for repair or replacement.
Under normal conditions the unit will be fit for in excess of 500 charge/discharge cycles, before
requiring battery replacement.
Feedback on the condition of the transmitter’s battery is provided every time it is activated.
• When fully charged, a short ‘confidence’ beeper sounds and the transmitter’s LEDs
illuminate green for approximately half a second.
• When running low, two beeps sound in quick succession and the transmitter’s LEDs flash
green twice. Although the transmitter will still work in this state, it must be recharged.
• When critically low, three fast beeps sound and the transmitter’s LEDs flash red. The
transmitter will be unable to transmit IR and RF calls and should be recharged immediately.
• Also, the Quantec system logs low battery signals at the Quantec Controller. This log will
need to be accessed to find out which units need their batteries charging (see COMPATIBILITY
ISSUES, page 4.)
RECHARGING THE TRANSMITTER
The transmitter must be charged using a QT424/1 single-way charger or a QT424/10 ten-way
charging unit for a period of 14 hours before it is first used. It should then be regularly
recharged (typically once a month, or more if usage demands it). Do not use any other type
of charging unit as this could damage the transmitter and void its warranty.
To charge the transmitter using the QT424/1 charger, simply
connect the charger to a standard 13 A mains socket and to
the 1.3 mm socket located next to the transmitter’s pull clip as
shown (right). To charge using the QT424/10 charger, please
refer to the separate instructions supplied with the charger.
Whilst charging, the transmitter’s two LEDs illuminate red and
when fully charged, the transmitter’s LEDs will flash red. Always
test the transmitter before using it is re-issued to its user.
TESTING THE TRANSMITTER
A Quantec IR test receiver, the QT302RT, is available to verify the correct IR operation of all
QT412 range transmitters. It is recommended that at least one is used per system. Please be
aware when testing the transmitter’s IR operation that any RF receivers within its range may
trigger at the same time.
WARNING: This transmitter should be regarded as a piece of life safety equipment. If
not sufficiently charged and regularly tested, the safety of those on site could be
compromised. Ensure systems are in place to guarantee the correct functionality of the
transmitter at all times.
