Location Function
IR and LF location
An alarm transceiver equipped with a location code receiver continuously receives
location codes that are sent out via IR light or LF magnetic field from fixed locators
in the system. The location codes are stored in the alarm transceiver and sent with
the alarm when it is activated. On the alarm computer, the transceiver's two latest
locations and direction of movement can be seen. The direction of movement and
speed can be determined by using the unit's last two location codes and the time
elapsed between them.
The pocket unit can also be used to test the fixed locators. The unit is then set to
indicate with beep and LED signals that a location code has been received. See also
the section
Pocket Unit Programmer
.
NOTE: The IR-receiver is situated
underneath the coloured transparent
plastic top. A transceiver with an
IR-receiver must always be carried visibly,
never covered!
Manual Location
If the function of the OK button is set to "Store", it is possible to store a manual
location. Enter the manual location code with the number keys. Press the Step-key
until "Store" is displayed and then press OK. The number can be recalled/displayed
by pressing a number key and then press the Step-key until "Recall" is displayed.
Press OK to recall the code.
The manual location code will be stored and sent with the alarm until a location
code that does not exist is entered, even if new IR- or LF location codes are re-
ceived.
Special Location
If the fixed locators are set to send a Special Location code, the pocket unit can
send an alarm directly after it has received the code. See also the section
