TM70 (7") / TM50 (5") Touchscreen Keypads
Installation
WIRING: For the TM70 it is recommended to use 18 gauge wire unless wire feed
one keypad and distance is less than 100ft./30m.
TM50 we recommend 18 gauge as well, however, 22 gauge can be used up to 150ft.
Feeding wire (bus) should not have more than 1.0V drop, each TM70 rep-
resents 0.3A max current, and TM50 150mA, wire resistance calculator can be
found on the web. Resistance per:100ft 22 gauge wire = 1.6 Ohm, 18 gauge
0.64 Ohm. Voltage drop formula:
V = 2R x 0.3N (TM70), V = 2R x 0.15N (TM50)
R = Wire resistance, N= Number of TM70s fed by the wire, use lower gauge
wire if necessary.
1. Separate the top assembly from the
back plate. Insert a flathead screw-
driver into the tab located, as shown
in Figure 1.
2. Mount the back plate to the wall or to
a gang box using appropriate screws.
Ensure that the UP arrow on the back
plate is in the up position.
Note: We recommend to feed
the TM70 with 18 gauge wire.

Secure the wire plug to the PCB socket the wires as per the color code to match the Paradox keypad bus code. The blue wire is keypad zone input. Attach the SD card cover if needed, then attach top to back top hooks first then lock the bottom as per Figure 1.
