Section 1 — CHC 140-1
Controller Introduction
and Operation
Controller
The CHC 140-1 is a System Controller for
up to 28 beacons. It synchronizes the
beacons and directs flash timing and
intensity, and records and reports beacon
operating status. It enables either
automatic or manual intensity control, and
it continuously displays the flashing status
of each individual system beacon. You can
manually control intensity by using a front
panel switch. Otherwise, a photocell sets
the intensity. Each beacon transmits a
confirmation signal when it flashes. All
beacons report to the controller over the
same twisted pair of conductors. This
composite signal is decoded for an array of
two-color LED indicators on the front
panel. An assigned indicator represents
each beacon in the system. Internal
memory retains a transient failure, until
you reset it manually; permitting you to
identify a beacon that only occasionally
misses a flash.
The CHC 140-1R fits in a standard 19-
inch equipment rack. System connections
are made at a terminal block at the rear of
the unit. The CHC 140-1W is in an
enclosure that allows the controller to be
wall mounted. The front of the enclosure
opens to reveal the operating controls. The
front panel has a glass window that allows
you to observe the indicator lights of the
controller. Otherwise, the CHC 140-1R
and CHC 140-1W are electrically the
same.

for available options.
Photocell
A photocell (PEC 510) directs intensity
stepping for the controller. It senses
changes in sky illumination and operates
switching devices at prescribed levels for
twilight and night. Housed in an outdoor
enclosure, it may be located at any
practical distance from the controller.
