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

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.

NOTE: For systems with more than two (2)

entrances, or other configurations, please

consult the factory or your nearest

Alpha Communications® distributor.

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).
