III. INSTALLATION
Installation Note:
During the Installation and Programming of the MCS Automatic Dialer, it is helpful to
use the Installation Checklist, found in the appendix. Worksheets for programming
Directory Telephone Lists are also available in the appendix.
III.A. Physical System Installation
Mount the system on a wall or other vertical surface, away from and protected from
harsh extremes. It is also recommended that the unit not be placed in close proximity to
high voltage (480 V and higher) electrical equipment. Four mounting holes on the top
and bottom mounting lips are to be used for system mounting.
There are six access holes on the bottom of the unit. The two left side ports are for
power connection and the system’s telephone line connection. The right side ports are
intended to be used for the entry of input/output conductors.
The Physical Installation Diagram, found in the appendix, shows the recommended
dimensions to be used in the physical installation of the system.
III.B.
Battery Installation
III.B.1.
System Battery
The battery installs in the bottom left side of the system. Open the system front panel
and retrieve the red and black battery leads from beneath the battery pocket area,
located to the left of the I/O Bus assembly. Connect the battery lead terminals on to the
new battery, BEING CERTAIN that the red lead connects to the positive (+) battery
terminal, and the black lead connects to the negative (-) battery terminal.
Insert (do not force) the battery, terminals pointed upwards, completely into the battery
pocket and close the system front panel. A new battery will take no longer than 24
hours to gain a full charge, and will be capable of powering the system through power
outages many hours in length. Actual battery backup time is dependent upon the
number of channels being monitored and the number of output relays which may be
activated. It should be noted that the LOW BATTERY indicator is only valid when the
120 VAC power is on. If the LOW BATTERY indicator stays on for more than 24 hours,
the battery is in need of replacement. Contact Microtel for replacement batteries. The
Microtel part number for the System Battery is #312156.
