Paradox TM70, TM50 Installation Manual

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 represents 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.

3. Make sure the SD card is installed properly and locked with text facing backward to wall/connections facing to the front, as shown in Figure 2.
4. 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.
5. Attach the SD card cover if needed, then attach top to back top hooks first then lock the bottom as per Figure 1. The SD card can be removed if necessary with a flat screw from the top if the metal cover is not attached or by opening the keypad for loading pictures.
6. Power up the bus and verify that the voltage is higher than 11.5V (displayed at the bottom right of the main screen as well as the boot sequence screen).
