154 MPA2C3 Installation Guide
Cables
Use industry-standard cables that meet the following specifications:
Table 6-1 Reader Cables
Recommended cable distances for readers and peripheral devices.
As readers can be connected only via the RJ45 terminals, the intention is to use
CAT cable. Via the MPA2RJ - RJ45 to terminal block convertor - other types of cable
can be used as well. The most common and most economic available cable cur-
rently is CAT 5E. We recommend that CAT5E F/UTP cable is used.
Note: Use only CAT x cable with 100% copper wires. We do not recommend cable with CCA
(Copper Cladded Aluminum) wires or CCS (Copper Cladded Steel) wires as this
decreases the maximum cable length to readers and locks significantly.
Note: When using the red RJ45 terminal connectors for door peripherals (locking device,
door contact and REX button) it is likely that the same cable will be used. The tests
have been performed with a 200mA lock.
