Preparing To Install The Emc And Accessories - Sentex EM3000 Installation Instructions Manual

Preparing to Install the EMC and Accessories

1. Locate a 110 VAC junction box that will be
suitable for your EMC installation:
The junction box, in most situations, will already be
installed from a building's initial installation. The
location of the junction box will be a determining
factor as to where your installation should take place.
The junction box must provide constant power, so
make sure the box does not have an ON/OFF switch
or other means that would shut off power to the
EMCs.
Note: If you cannot locate an appropriate junction box to power the EMC, power the system
directly from the breaker box.
2. Determine which breaker in the breaker box powers the 110 VAC junction box:
With any high-voltage electrical work, a qualified electrician will need to know which breaker
powers the local junction box.
3. Review and pick out locations to mount your EMC(s):
Look for locations that are within 500 ft. of your access control points. Make sure that your
locations are also safe from temperature variations, environmental changes, and access from
outsiders.
4. Review reader and door hardware materials for mounting requirement:
Will you require special tools when installing your system? When installing a reader, always follow
the instructions outlined in the reader's instruction guide(s).
5. Prep and cut door frames for lock and door sense hardware:
In most cases, the doorframes will be metal. You may need to use metal snips and a drill to size
and secure the lock hardware and your door sense to both the frame and the door itself. For
wooden frames, you may need wood working tools.
6. Cut out dry wall access points for the door hardware and reader:
Where will your readers be located? Make sure that your access points correspond to the
locations where you plan to have your hardware. If you are using REXs or PIRs, make sure
placement of access points are on the opposite side of the wall from the readers.
Step 4: Installation of the EM3000 System
Power to the local junction box
must be OFF during the connection
between the junction box to the 12
VDC power supply board. You may
need to supply extra lighting to the
installation area during the time power
is off.
