Operation, Installation, and Maintenance Manual

LW-401

To Acknowledge Alarms

1. Unlock and open the door.

2. Press ACK to acknowledge (Block

Acknowledge) all alarms and other
conditions. The system ALARM and the
Zone ALARM LEDs on the front panel
stop flashing and remain on. The
system’s internal audible silences.

To Silence The Notification Appliance
Circuits

Press SILENCE after all alarms are acknowl-
edged. The BYPASS LED on the front panel
flashes. The following four conditions are
checked before the Notification Appliance
Circuit(s) can be silenced:

1. If either NAC is programmed as NON-

SILENCEABLE, it will not silence.

2. If the NAC inhibit timer has been pro-

grammed (see

 Set System Timing on

page 13), the NAC will not silence until
the inhibit time delay has expired (6
seconds to 5 minutes.)

3. If either NAC is programmed for temporal

coding, it will complete sending out
the entire current temporal round before
silencing.

4. If either NAC is programmed for ZONE

CODING, all coded rounds for each
zone in alarm must be sent out before
the NAC will silence.

Once the NACs have silenced, pressing the
SILENCE a second time causes the Notifica-
tion Appliance Circuits to re-sound, and the
BYPASS LED to turn off.

To Reset

Press RESET. (The system will not reset
until all alarms, supervisories, and troubles
are acknowledged and all conditions are
returned to normal.)

Responding to a Supervisory
Condition

How the System Annunciates
Supervisories

When a supervisory condition is detected, the
system causes the SUPERVISORY LED and
one of the yellow Zone TROUBLE LEDs on
the front panel to flash and the system’s
internal audible to sound.

To Acknowledge Supervisories

1. Unlock and open the door.

2. Press ACK to acknowledge (Block

Acknowledge) all supervisory and other
conditions. The system SUPERVISORY
and the Zone TROUBLE LEDs on the
front panel stop flashing and remain on
and the system’s internal audible silences.

To Reset

Press RESET. (The system will not reset
until all alarms, supervisories, and troubles
are acknowledged and all conditions are
returned to normal.)

Responding to a Trouble Condition

How the System Annunciates Troubles

When a trouble is detected, the system
causes the TROUBLE LED and the appro-
priate yellow Zone TROUBLE LEDs on the
front panel to flash and the system’s internal
audible to sound. Troubles will clear prior to
Acknowledge if the condition which caused
the trouble returns to normal.

Note:  Exceptions are Class A zone troubles

which always latch.

System troubles are also annunciated by the
appropriate trouble code in the 7-segment
