Notes:
1. Use #18AWG wiring to transformer and door opener. All other wiring can be #22AWG.
2. Talk down volume can be adjusted using volume control (potentiometer) on NH209TT amplifier/power supply.
3. When connecting to a magnetic door lock or other 'fail safe' type door lock, use the optional model PK407A
specialty relay, for each entrance door lock.
4. If the NH209TT amplifier is not mounted behind the entry door station, and is mounted remotely, we recommend
using shielded cable from the speaker/microphone wires to the NH209TT amplifier/power supply.
5. Transformer and door opener wiring MUST NOT be in same cable as handset wiring!!!
6. Observe all local and national electrical codes.
