TYPICAL WIRING DIAGRAM FOR DUAL ENTRANCE SYSTEM
WITH S.T.R.™ STYLE CAMERA AND ONE (1) VIDEO RISER
(NO VIDEO DISTRIBUTORS) AND 1-4 MONITORS
NOTE: For systems with more than two (2)
entrances, or other configurations, please
consult the factory or your nearest
Alpha Communications® distributor.
Notes:
1. All wiring is #22AWG unless shown otherwise.
2. When using a PINHOLE type camera, instead of the standard S.T.R.™ type camera, see the special camera
installation and connection instructions found on page 9, and do not power as shown above.
3. The most recent NH208TVU has two (2) 'O' and '8V' terminals. They are duplicated for ease of wiring. You
may use either or both. Both sets are internally connected together inside the NH208TVU on the p.c. board.
4. DO NOT CONNECT MORE THAN 10 MONITORS PER VIDEO RISER/LINE.
5. Observe all local and national electrical and building codes.
6. All terminals connections shown may not be in the order that they appear on the equipment.
Notes:
All Model HT2006/5 (5-button) Master Handsets shown. You
may also use HT2006/10 (10-button) Master Handsets which
basically wire the same as the 5-button handsets, except they also
have terminals '6' thru '10' as well as '1' thru '5'.
Terminals '1' thru '5' (on the HT2006/5) and terminals '1' thru '10'
(on the HT2006/10) are the calling out terminals and terminal 'Z'
is the terminal that determines the handset number that is called.
This configuration shows a 1-button door entry station that
signals all four (4) HT2006 handsets simultaneously. You may
use a multi-button door entry station, by connecting the selective
button wire(s) to terminal 'R' on the corresponding HT2006
handset(s) being called by that button.
Each handset that is called by a door station must have the model
R2006 Alphatone™ signaling module installed (see page 4).
The Electric Door Opener shown in this illustration is activated
by depressing button #5 on each of the HT2006 handsets. Each
HT2006 handset comes with a separate plastic 'KEY SYMBOL'
button that may be substituted for the numbered door release button
used (if desired).
