Gen
and
Dir
(see Figure 16 on

6. Press UP or DOWN key to change direction.
The generator alarm notification relay has dry contacts.
The
Dir
(direction) is the position of the relay without
generator operation.
NO
is normally open;
NC
is
normally closed.
When the
Val
(value) is
ON
, the relay is in an alarm
condition. The relay connections (generator alarm) are
on the LC6000 terminal block; see Table 6 on page 34
for terminal block index.
Emergency Vent Alarm
If the emergency vent terminals are activated by a
hydrogen detector or similar device, an alarm will
be generated and the wall units will all be put into
emergency ventilation by the LC. 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 zones ventilate during this event.
Units with economizers will operate in emergency vent
mode. The dampers will open at 100% and the blower
will come on at full speed until the alarm is reset.
Units without economizers located in the same zone
will only bring on the blower at full speed.
The emergency vent 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 (#8
and #9). When this jumper is removed, the alarm will
become active.
To change the direction of the emergency vent 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

5. Press ENTER key to scroll to the variable in the
table that intersects
EM Vent
and
Dir
(see Figure
15 on page 16).
6. Press UP or DOWN key to change direction.
Emergency Vent (EM Vent)
Dir
(direction) is the
position of the emergency vent contacts in the event
of hydrogen being sensed.
NO
is normally open;
NC
is
normally closed.
EM Vent
En
(enable) allows the LC controller to monitor
the hydrogen detector when set to
ON
. When set to
OFF
, the LC controller ignores the hydrogen detector.
EM Vent
Val
(value) of
ON
indicates a hydrogen event.
A
Val
(value) of
OFF
indicates no hydrogen event.
Emergency vent connections (hydrogen detector input)
are on the LC6000 terminal block; see Table 6 on page
34 for terminal block index.

The emergency vent alarm notification relay has dry
contacts. The
Dir
(direction) is the position of the relay
without a hydrogen event.
NO
is normally open;
NC
is
normally closed.
When the
Val
(value) is

, the relay is in an alarm
condition. The relay connections (emergency vent
alarm) are on the LC6000 terminal block; see Table 6
on page 34 for terminal block index.
Zone Unit Alarm
By default, if any of the units communicate a high
pressure or low pressure alarm to the LC, the LC will
actuate a relay output to provide remote notification
of the event. A relay output will be actuated from the
Manual 2100-669F
