Intended use

The product is designed to be placed close to the user’s head, for example, so that the alarm can be activated by turning the user’s head towards KK901. KK901 can be used when the user cannot activate an alarm with a pull cord or push button.KK901 can activate a KNOP 900 series wireless receiver. Pay attention to the range as described in the section “Checking the coverage area”.

Commissioning
After installation, it is important that the user and staff test the product. Staff should receive an alarm on their alarm device/receiver. Refer to the user manual of the receivers used.

Check the coverage area
One person activates KK901 (as described above), while another person systematically walks around the area and makes a sketch of the building and the area where there is protection. The sketch 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.
The coverage area can be increased by using a repeater system from KNOP Elektronik. Contact your dealer for more information.

Service
When the user activates KK901, it will flash a green light. The recipient sends back a confirmation, after which KK901 lights up constantly in green, indicating that the transmission was successful. If the transmission fails, KK901 lights up red and repeats the transmission up to two times at 30-second intervals.

Location
KK901 should be positioned so that the user can easily activate the ball on the switch. For example, the child switch can be mounted on a gooseneck, contact your dealer for more information.
