MITECH MIKRA Installation And User Manual

MIKRA is the mini double IR barrier with parallel beams with optical synchronization. It is composed of two symmetrical bars to be
installed on either sides of the entrances to be protected and it allows to anticipate intrusion by leaving freedom to move indoors with
even windows and doors open.

TECHNICAL FEATURES AND CONSUMPTION:

Maximum range: 4 m - minimum range: 50 cm
Operating temperature: -15°C + 60°C
Synchronization: optical
Led indicators: synchronization – alarm
Detection system: linear beams (OR o AND) – crossed beams (AND)
Power supply: from 12V to 15V, best 13.8 V
Motherboards consumption (TX + RX): max. 40 mA
Additional expansion consumption (TX + RX): max. 8 mA
Tripping time: from 120 to 240 mSec (recovery time: 1 sec)
Output: NC (alarm and tamper)
Protection class: IP44

INSTALLATION AND PROGRAMMING DETECTION SYSTEM

(See page 2 for connections)
1. Open the caps and using the appropriate holes (see image on the side) fix the
profiles making sure to keep them on the same axis.
2. Power the barriers and make connections (use shielded cables and connect the
shield).
3. To check the detection system set, press and hold the MODE switch on the
receiving barrier until the SYNC LED or ALLA LED begin to flash, alone or
together, for a few seconds.
Compare the flashing of the leds with the DETECTION SYSTEM TABLE (by
releasing the switch, the leds will stop flashing after 5 seconds and only the SYNC
LED should remain lit steadily).

4. To change the detection system set, follow the procedure below:
Press and hold the MODE switch on the receiving barrier until the leds flashing.
Once the leds flashing, press the MODE switch again to select the desired
operating mode (see DETECTION SYSTEM TABLE ).
Once the operating mode has been defined, release the switch.
After 5 seconds, the leds will stop flashing and only the SYNC LED must remain lit
steadily.
