Intended use
TX901A is a small battery-powered waterproof transmitter, available both as a wrist transmitter
(TX901A) and a neck transmitter (TX901A-H).
TX901A-T has an additional pressure plate, which is designed for people who, for example, have
arthritis in their fingers or have difficulty hitting the red alarm button.
If the transmitter is encoded in a receiver with a display, the citizen's name and possible apartment
number can be shown in the display, if this is encoded when the transmitter is activated.
On activation of the red button or the keypad, the indicator lights up briefly in green.
When the alarm is received by the receiver, the indicator lights green again briefly whereas if the
transmission is unsuccessful, the indicator lights red. The product will repeat the transmission up to
2 times at 30-second intervals.
If the indicator flashes red/green rapidly after activation, the battery needs to be written to.
Putting into service:
The product is ready to use and only requires encoding in the desired receivers.

Checking the coverage area
One person activates the TX901A (as described above) at short intervals, while another
systematically walks around the area and marks a sketch of the building and the area
where there is coverage. The sketch is placed in the office so that anyone who needs to
operate the system can see where there is coverage.
Outside the coverage area, alarms cannot be received.
The coverage area can be increased by using a repeater system from Knop Elektronik.
Contact your dealer for details.
