Intended use
The product is designed to activate a KNOP 900 series wireless receiver when a
user presses the button.
PU901 can be used when the user cannot activate an alarm with a pull cord or
push button.
PU901 must be coded into the receiver and the receiver must be switched on for
the system to work.
Pay attention to the range as described in the section “Checking the coverage
area”.
Testing and commissioning
After installation, it is important that the user tests the product by blowing
against the propeller.
Staff should receive an alarm to their alarm system/receiver.
Refer to the instruction manual of the receivers used.
Check the coverage area
One person activates PU901 (as described above), while another person
systematically walks around the area and makes a sketch of the building and
the area where there is coverage. The sketch is placed in the office so that
everyone 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 retailer for more information.
Location
PU901 should be positioned so that the user can easily blow straight into the
propeller.
The push contact can be mounted on e.g. a gooseneck, contact your retailer for
more information.
Service
When the user blows hard enough on the propeller to activate PU901, it will
flash a green light.
The receiver will give an acknowledgement, after which PU901 will glow steady
green, indicating that the transmission was successful.
If the transmission fails, PU901 repeats the transmission up to 2 times at 30
second intervals.
Battery alarm
If the battery in PU901 is low, the receiver will display “Low battery” when an alarm is received from PU901.
Changing the battery
The top and bottom of the PU901 can be unscrewed without tools.
After replacing the battery, check PU901 as described under “Testing and
commissioning”.
It takes about 1 minute after battery replacement before it can be activated.
