Generator Alarm
If the LC detects a generator running event (through a
digital input), an alarm will be generated. Additionally,
a relay output will be actuated from the LC to provide
remote notification of the event. The end user will be
able to configure which units are permitted to run during
this event.
Default will be to not allow any units to run.
The generator alarm input can be configured to accept
either normally open or normally closed inputs. The
controller is defaulted to normally open and a jumper
is placed across the terminals of the input (#10 and
#11). When this jumper is removed, the alarm will
become active.
To change the direction of the generator input:
1. Press MENU key to go to the Main Menu screen.
2. Use UP or DOWN keys and ENTER key to enter
USER password 2000.
3. Press UP or DOWN keys to scroll to
IO Config
;
press ENTER key.
4. Press UP or DOWN keys to scroll to
Digital In
Config C1
.
5. Press ENTER key to scroll to the variable in the
table that intersects
Gen
and
Dir
(see Figure 15).
6. Press UP or DOWN key to change direction.
Gen
Dir
(direction) is the position of the generator
input contacts in the event of a need for generator
operation.
NO
is normally open;
NC
is normally closed.
Gen
En
(enable) allows the LC controller to monitor
the generator input contacts when set to
ON
. When set
to
OFF
, the LC controller ignores the generator input
contacts.
Gen
Val
(value) of
ON
indicates the generator is in
operation. A
Val
(value) of
OFF
indicates the generator
is not operating.
Generator connections (generator run input) are on the
LC6000 terminal block; see Table 6 on page 34 for
terminal block index.
While the generator is running, the system will
only allow selected units to run. This selection is
customizable by the end user. This limitation is in
place to match the unit power requirements to the
shelter generator capacity.
The default is to not allow any units to run during a
generator event.
This can be adjusted to allow specific
units to run during a generator event.
To change which units run when the generator run
input is active:
1. Press MENU key to go to the Main Menu screen.
2. Use UP or DOWN keys and ENTER key to enter
TECHNICIAN password 1313.
3. Press UP or DOWN keys to scroll to
Adv System

The smoke alarm notification relay has dry contacts.
The
Dir
(direction) is the position of the relay without
a smoke event.
NO
is normally open;
NC
is normally
closed.
When the
Val
(value) is
ON
, the relay is in an alarm
condition. The relay connections (smoke alarm) are on
the LC6000 terminal block; see Table 6 on page 34 for
terminal block index.
