Warnings and safety instructions

The battery in this product must compile with the relevant IEC safety standards for batteries.
Please read the intended use before use.
Do not consume or eat the battery, there is a risk of chemical burns.
Keep new and used batteries away from children.
If the battery compartment cannot be closed properly, discard the product, and keep it away from children.

Intended use

TX901 is a transmitter designed to send calls to receivers where the transmitter is encoded.
The transmission is done by pressing a button on the transmitter or by activating an input as described under “External connection”.
The product has four buttons that can be displayed as individual calls on RX901 (requires software version 3.1 or later). External inputs can be used, for example, with treadmills or push buttons.
TX901 has a built-in magnetic contact, so it can be used as a door guard or door sensor.
Pay attention to the range as described in the section “Checking the coverage area”.
Adapter cables are available as accessories – see www.knop.dk.
When the red button or the pressure plate is activated, the indicator lights green briefly. When the alarm is received by the receiver, the indicator lights green again briefly, while the indicator lights red if the transmission fails. The product repeats the transmission up to two times at 30 second intervals.
If the LED flashes red every five minutes, the battery needs to be recharged.
It is possible to set the product to send either a panic call or an alarm call with the KNOP logo to e.g., staff to indicate.
“I need help” with a patient or as an assault alarm. In order to use and set up some of these advanced functions, the KNOPtool and the corresponding USB90X (PC software and USB key) must be used. At the same time, it allows you to update this and other products.

Commissioning

Once the batteries are installed, see the point battery replacement, the product is ready to be used and encoded in the desired receivers.
Some advanced features require the receivers to be updated to the latest software version, this update is done with KNOPtool.

Battery alarm

Check the battery regularly, when the batteries need to be replaced it will flash red every five minutes. When the product is activated, a battery alarm is also sent to the receiver’s display, where the display may show “Low battery”.

Changing the battery

When replacing the battery, the screw on the back of the case is loosened and the top and bottom sides are separated. 2 x 1.5V LR1 batteries are used. REMEMBER to turn the batteries correctly.

Timer

It is possible to use timers in TX901 that can turn on/off door protection, buttons and/or external input within the same time interval. If the clock is not set, the timer is switched off. The timer is set in the KNOPtool.

Set the clock

TX901’s clock is automatically set from the receiver with display, USB90X or MR902 (system). The clock can be set manually:

Set the clock in a receiver with display (from version 3.4.17).
Activate TX901 (TX901 must be encoded on RX901) within one hour.

Once the clock is set, the timer and any door protection are set to be active or not active according to the timer setting.

On/Off

It is possible to switch off the product to save power if the product is not used for a long time. However, the function cannot be used when door protection is selected.
OFF: Press and hold the RED button – it flashes green – when it lights up red, the product is turned off.
ON: Press and hold the GREEN button – it flashes red – when it lights up green, the product is on.

Positioning

TX901 has built-in positioning. This requires a system with POS901 from Knop Elektronik. The POS901 sends positioning codes that TX901 can receive. The positioning system also requires the use of receivers with display. However, the function must be activated and set via KNOPtool.

External connection

TX901 has both a normal open and a normal closed input.
The jack contact is an input that can be used for e.g. foot pedal switches or push button switches with end function between frame and tip (NO).
NC is a switching function between normal functions and can be used, for example, for a bed mat to give an alarm when the patient leaves the bed.

The modular RJ45 connector provides external inputs and external power supply.
KNOP tool is required to set up these inputs and their use correctly, see KNOP tool about this. In addition, the receivers need to be updated to the latest software version to achieve full utilization.
Note that inputs 1 and 2 of the modular connector are the same as NC/NO of the jack connector.

Modular connector

Pin 1: Input 1 (Jack NO)
Pin 2: Input 2 (Jack NC)
Pin 3: Input 3
Pin 4: Input 4
Pin 5: 3V output, max 20mA
Pin 6: Input AD 0-10V
Pin 7: External supply 5-14V
Pin 8: GND

TX901 has a standard bed/seat connector function on input 2 of the RJ45 connector or the NC pin of the mini connector. The bed/seat switch from Knop Elektronik fits directly into the connector and the function works undisturbed.
There is an automatic delay of 2 seconds for activation of the alarm. The delay can be changed in KNOPtool between 0 and 10 seconds.
Also, in KNOPtool the pressure gauge can be switched off so that the input can be used as a normal alarm function.
Note: The cable used must not be longer than 3 meters for the RJ45 and mini-jack connectors.

TX901 as door protection/door sensor:

Mount the TX901 on the sill with Velcro. Mount the magnet on the door next to TX901 so that the upper edges are flush with each other. The distance between TX901 and the magnet must not exceed 5 mm. The magnet can be placed either on the right or left side of the TX901. Magnet and Velcro are accessories and can be ordered with article number 2301.

Door sensor: By default, an alarm is sent when the door is opened, but it is possible to change this in KNOPtool to open or/and closed. In the door sensor it is still possible to use the buttons on the TX901 for alarms.
Door protection: The door protection works slightly differently than the door sensor. The four buttons 1-4 now control the door protection.
NOTE: It is not possible to use the OFF/OFF function.

GREEN Turn off the door protection regardless of the timer setting.
RED Turn on the door protection regardless of the timer setting.
YELLOW 10 seconds delay in case of alarm (flashing green) or alarm off (flashing red).
BLUE Turn off or on according to the timer setting. The LED indicates whether the door protection is on (red) or off (green).

There are two options for placing the door protection, either on the outside or on the inside of the door.
Settings of the door protection can be made in KNOPtool, including the possibility to use external 1 input instead of the internal switch. It is also possible to disable individual buttons in KNOPtool if the function is not desired.
Activation of internal or external can be done locally by removing the batteries for at least 30 seconds.

Then press and hold either button 2 (red) for external placement or button 3 (yellow) for internal placement while inserting the batteries.
The indicator flashes red.
Do not release the button until the indicator flashes green after about 10 seconds.

If the door protection is to be deleted, this is done with KNOPtool or via the factory settings (all settings are deleted).

Typical use pattern for outdoor placement.

Press the yellow button before the door opens. The LED will now flash green rapidly. Go inside and close the door – within 10 seconds.
When you want to leave, open the door, walk out and close it behind you.
Note that the LED is now flashing red.
Press the yellow button – within 10 seconds to cancel an upcoming alarm.

Maintenance

Update of TX901
It is possible to update the software of TX901. For further instructions please check the KNOPtool.

Check the coverage area

One person activates the product at short intervals, while another person systematically walks around the area and marks on a sketch the building and the area where there is coverage. The map is placed in the office so that anyone who needs to use the system can see where there is coverage. Outside the coverage area, alarms cannot be received. Coverage can be increased by using KNOP’s MR902/RP902 repeater system. Contact your retailer for more information.

Reset of the product

TX901 can be reset to factory settings.

Remove the batteries for at least 30 seconds.
Then press and hold button 4 while inserting the batteries.
The indicator flashes red
Do not release button 4 until the indicator flashes green after about 10 seconds.

TX901 has returned to factory settings.
