A PRODUCT OF THE GENFLEX SYSTEM

ALARM FOR MASTER SYNC GENERATORS

MODEL PCA-819

FEATURES

 Alarm Condition of SPG
 Audible Tone
 Contact Closure

The PCA-819 Remote Changeover Alarm is an
add-on enhancement to the PCO-818 changeover
system. The PCA-819 is engineered to provide a
convenient, and easy to use means of monitoring
changeover, due to loss of signal, at a remote
location.

Bi-color LED’s provide a visual indication of the
Changeover Frame status. Additionally, an
audible alarm sounds to indicate an alarm
condition. And to provide even more flexibility,
isolated relay contacts, both normally open, and
normally closed, are provided so the user can
control other equipment or alarms in the event of
a loss of signal at the Changeover Frame. Front
panel switches allow the user to disable the alarm
signal from either, or both, generator banks, and
also mute the audible alarm.

The PCA-819 is housed in a rugged 1RU rack­mount enclosure, and can be powered from 120 or
240VAC (internal jumper selectable).

 Disable Alarm
 Connects to PCO-818
 120 or 240 AC Operation

The PCA-819 has two Digital inputs, Gen A and
Gen B. These signals are input on TB1 located on
the rear panel. A three-wire cable connects TB1 to
J3 on the rear of the PCO-818 frame. These
signals are active high, TTL level. Input A and/or
B can be disabled by their respective
enable/disable switch on the front panel. The
inputs are filtered for noise and clipped at 5.1V for
transient protection. Bi-color LED’s indicate an
RED alarm condition , GREEN condition OK, and
BLINKING GREEN unit has been disabled.

A circuit detects if either or both inputs, Gen A or
Gen B, has a failure, the speaker sounds off and
the relay is energized. The speaker is a self­generating audible indicator and may be muted by
by front panel switches. The alarm output relay
provides both Normally Open and Normally
Closed contacts, capable of switching up to 5
amps at 120VAC or 30VDC. Varistors and a fuse
protect the contacts the relay from transient spikes
and overloads.

MADE IN THE USA

Whenever a loss of signal occurs on any of the
various changeover modules in the PCO-818, an
alarm signal is generated and the PCA-819 shows
the alarm condition on the front panel.

The PCA-819 is powered from the AC line, with
the option of either 120V or 240V, by changing the
appropriate jumpers at JP1, JP2, and JP3.
