ASSEMBLING THE KEYPAD
6.1
Choosing a location
PU-R should be located in a place assessable for a user considering the following
recommendations:
Locate PU-R in a close proximity to the wireless expander functioning as a
network coordinator (RR 0).
Communication distance with the wireless expander through the wireless in-
terface at the open territory is up to 800 m. The communication distance in-
side, however, depends on a number of walls and partitions, as well as their
material type, and might be significantly decreased. Before PU-R installa-
tion, evaluate communication quality by using the pictograph
located at
the right top part of the screen. Communication quality should be evaluated
not less than “good” (two vertical strips).
Communication distance with the wireless expander through the interface
RS-232 is up to 30 m.
Should daily arming/disarming be controlled by PU-R, install the keypad in
close proximity to an entrance door
Install PU-R at the distance of not far than 1.5 m from the wireless expander.
If possible, install the keypad far from (the minimum distance is 0.5 m) metal
objects, metal doors, metallized window openings, etc., as well as current-
carrying cables, wires, especially computer wires, otherwise communication
distance might be greatly decreased.
Do not install the keypad close to various electronic and computer devices to
prevent interferences from functioning energy converter, microprocessors,
etc. to affect radio reception.

Installation
Before assembling the keypad with the wireless interface, remember to firstly reg-
ister the keypad in the wireless expander by using a wired interface (see the para-
graph 5.3, page 34).
