Chapter 3: Install the Communication Hub

Instructions

Placement

of the Hub

For a stable and reliable radio link it is recommended that the distance between the lock and the

Communication Hub is limited to 15 feet (5m). However, under good conditions (free air between the

units and limited radio interference from other transmitters) it is sometimes possible to increase the

distance to 35-45 feet (10-15m). Under poor conditions (heavy radio interface, etc.) it may be necessary

to keep the distance between the lock and the Communication Hub well below 15 feet (5m). There is no

minimum distance. If suitable, several Communication Hubs can be positioned together as long as the

Hub-to-Hub distance is 1 foot (.2m) or more.

Figure 2. Placement of Communication Hub

Typically, the LED on the Communication Hub cover should “point” to the lock.

 The Communication Hub should be placed on the non-secure (key or card) side of the door.

Shorter distance and “light” materials in the walls permits placement on opposite sides.

 Be aware of that metallic sheet or mesh will attenuate the radio signal. Inner ceiling is, for

example, sometimes covered with foil or metallic mesh.

 Mirrors and larger metallic objects (like cable ladders) should kept at least 1 foot (2m) away

from lock or Communication Hub.

 WiFi / WLAN routers and other radio transmitters operating in the 2.4 GHz band should be kept

at least 11-12 feet (3-5m) from the Communication Hub and lock.

 Other possible sources of interference include microwave ovens, electric motors and other

high power electrical equipment. Keep at least 8-10 feet (2.5m) distance between the

Communication Hub and lock.
