Low Chamber Val; Maintenance Req; Pre-Alarm Alert - Notifier AM2020 User Manual

LAN COMMUNICATION FAILURE*
The specific network node (panel) can no longer communicate with the rest of the network, indicating a problem
with the network connections.

LOW CHAMBER VAL

The chamber value of the detector is too low for operation. This indicates a malfunction in the detector. The
detector must be removed and replaced by an authorized service representative.

MAINTENANCE REQ

The chamber value of the detector has exceeded 80 percent of the Alarm Threshold (determined by the
sensitivity selection of Low, Medium, or High), and has remained there for at least a 26-hour period. This
condition may be due to a dirty detector. The detector should be inspected and cleaned as necessary by an
authorized service representative. Failure to do so may eventually result in false alarms.
MANUAL CONTROL
This annunciator is being controlled manually.

PRE-ALARM ALERT

The chamber value of the detector has exceeded 80% of the alarm threshold (determined by the sensitivity
selection of Low, Medium or High), and has remained there for at least a 60-second period. This condition
may be due to a dirty detector. The detector should be inspected and cleaned as necessary by an authorized
service representative. Failure to do so may eventually result in false alarms.
POINT TROUBLE
A monitor module dedicated to monitoring trouble conditions has been activated.
SECURITY ALARM
A security device programmed as SARM has been activated indicating a burglary or security violation. This
condition should be checked immediately.
SECURITY ALERT
A security device programmed as SACM has been activated indicating that a monitored event has occurred.
SECURITY TAMPER
A security device programmed as SSYM or SEQM has been activated indicating that monitored equipment
has been tampered with. This condition should be checked immediately for a SSYM device because it may be
due to a burglary or security violation.
SECURITY NO COM
The AM2020/AFP1010 has received either no response or an invalid response from an addressable SLC loop
device programmed for security operation. This may be the result of a burglary, other security violation, the
failure of a device, an improperly addressed device, or failure of the field wiring.
SPRNKLR TROUBLE
A supervisory condition that indicates sprinkler equipment supervised by a monitor module is in an abnormal
state (i.e. a sprinkler valve has been closed). Note that a break in the wiring of a supervisory circuit is a
trouble condition that yields OPEN CIRCUIT, not SPRNKLR TROUBLE.
SUPRVSRY SIGNAL
A supervisory condition that indicates equipment supervised by a monitor module is in an abnormal state (i.e.
low pressure indication). Note that a break in the wiring of a supervisory circuit is a trouble condition that
yields OPEN CIRCUIT, not SUPRVSRY SIGNAL.
VER COUNT OVFLW
This detector has exceeded the allowed detector verification limit. This condition may be due to a dirty
detector. The detector should be inspected and cleaned as necessary by an authorized service
representative. Failure to do so may eventually result in false alarms.
