How to Use the Efir-K for Electromechanical Device Manipulation
1.
Program the Receiver to be of operating mode #3 as explained before.
2. Program the needful number of Keyfobs to be in use.
3. Attach the Receiver at a suitable location where all programmed Keyfobs are operating. Keep in
mind all mounting recommendations given on page 3.
4. Wire the Receiver in accordance with the connecting diagram presented in Figure 5.
Let’s consider the specific example of such a system operating for an electromagnetic lock. In case of
sound or visual alarm, motor or video camera manipulations the process is similar.
Initially an entrance door is closed, and the lock is switched on. When an owner is about going away,
he presses and holds the large Keyfob button sending out an encrypted executive signal. The Receiver detects
the signal and decodes it. If the signal is authorized the switch-over dry contacts are opened following by the
lock opening. In such a process the Receiver LED shall light by red.
After having gone from the object the owner closes the door and releases the large Key button. The
Receiver LED shall go out. The lock switches on blocking the door.
Coming back the owner repeats actions described before. If he stands within coverage area the
Receiver opens the door, the Receiver LED lighting by red. After having entered the owner releases the large
button, after which the lock is closed and the LED goes out.
Dwelling within the building an owner in such a manner can provide a selective access control or
garage door opener (or any movable barrier) manipulating.
