8.6. GENERAL RECOMMENDATIONS ON WIRELESS COMPONENTS ON-
SITE PLACEMENT

Do not place wireless devices directly on massive metal constructions to avoid
distortion of antenna pattern;

Do not place central control panel Astra-8945 Pro, wireless zones extenders and
wireless devices inside metal constructions (metal boxes, safes etc.) or use re-
mote antenna to secure wireless connection;

Wireless relay unit Astra-Z-8245, when installed into metal box, must be con-
nected with remote antenna (included into delivery set);

Do not place power supply wires of the central control panel and routers in cable
channels jointly with high-power cables of AC 220-380 V power nets;

Do not place wireless devices close to (min 1 m away of) sources of radio inter-
ference (medical devices that use electromagnetic field during operation, video
signal processing devices and computer hardware, antennas and radio fre-
quency tracts of communication devices, including radio message transmitting
systems, etc.);

Place wireless devices (except the control panel, keypad, FCP, wireless relay unit
and WLD) as high as possible and no lower than 2 m away of the floor; as a
rule, at this height there are the fewest obstacles, and this height also ensures
normal functioning conditions for IR, AC, MC, and SD, HD type of detectors ac-
cording to the physical principles of detection;

Place wireless devices no closer than 10 cm away of the surface of walls and ceil-
ings that contain closely spaced metal reinforcement (reinforced concrete) or
fine mesh reinforcement (less than 4 cm) under plaster surfaces;

During placement, ensure the least possible deviation from direct view and ob-
struction by foreign objects between directly communicating wireless devices;

In premises with high human occupancy, place wireless devices so as to ensure
backup data transfer routes, as people moving throughout the space can
weaken wireless signals;
