Wire runs
Cabling used to supply power should be a jacketed Class-2 type with a 20AWG minimum.
Refer to Table 1 for recommended wire gauges based on cable lengths.
For multi-drop systems when more than 3 repeaters are connected to the same 24VAC
supply, it is recommended that 18AWG or larger be used. As a rule of thumb, the supply
transformer should be increased by 5VA for each 24VAC RPT on a multi-drop system.
Insure all wiring meets the NEC Article 300, Section 725.3 for Class-2 and wiring.
wiring in ducts, plenums, and other spaces related to the air handler, NEC 300.22 should
be followed. Type CL2P cabling should be used were appropriate.
Additionally, DC power may be supplied using an AC/DC wall wart (Cypress
Envirosystems part number: WPT-810-DCPS). This part plugs into a standard 120VAC
outlet and supplies 5VDC for the RPT.
