Elkron ER3000-RF Bus Radio Expansion Board 80WL0710111

LER3000-RF is an expansion module that allows Elkron 868 MHz radio devices to be added to the system. The module is connected to the control panel via BUS.

Mounting:

• The expansion can be mounted inside the control panel or in CP/EXP wall boxes, with the tamper connected to the TAMPER input. It can be installed inside distribution boxes or similar containers, adequately protected by tamper devices (tamper). Since this is a radio transmitter/receiver device, the expansion must be installed with all precautions typical of installations of this type. Place the expansion in a non-passing indoor location, not subject to excessive temperature changes, protected by the burglar alarm system and away from strong electromagnetic fields.
  
  
  

Bus Connection:

• The expansion can be connected on the bus in cascade, star, or mixed mode. The location along the bus does not matter. The total length of the bus leg should not exceed 500 meters (cable sect. 2x0.75 mm2 power + 2x0.22 mm2 data). Connect the expansion to the bus using terminals +, A, B. If the expansion is mounted in the control panel, the bus connection can also be made with the special cable, supplied, connected to the dedicated connector (see figure point C).
