Important Points to Note
Using Your Door Intercom Adapter
23
You must attach your Door Intercom Adapter to line 1 for it to function.
Your Door Intercom Adapter is designed to be compatible with NUTONE
brand door speakers (such as model ISB-64 and model IS-69), and is also
compatible with their lighted pushbutton. The Door Intercom Adapter may
possibly work with other brands of door speaker, but has not been tested
for compatibility with any other brands.
You may connect up to four Door Intercom Adapters to your system. Connect
each one to a separate door intercom speaker and assign each one a different
station number from 23 to 26.
If you install a magnetic door strike to the system, you must remember to pro-
vide your own 12 volt DC power supply to the magnetic door strike. The Door
Intercom Adapter provides only the momentary closure relay, and does not itself
provide any power to the magnetic door lock.
