Alarm 1/Alarm 2 incidents and actions
The primary purpose of the ACM 150 monitor is to generate a Alarm 1/Alarm 2
Incident whenever the level of a hazardous gas exceeds set point limits. Such
incidents cause a number of actions to occur automatically:
• The Alarm 1 or Alarm 2 condition changes on the
scan results.
• The data is logged as a recent Alarm 1/Alarm 2 incident
log).
• One or more relays activate, which is determined by the setup program for the
relays (Relay
• The incident is archived along with the infrared spectrum
• The data is available for graphical trending
• These incidents, along with the normal scan data, are available for interfacing to
a PLC or network computer Ethernet or Lonworks.
• Network or remote computers connected via Internet protocol may be set to print
each incident as it occurs.
Alarm 1/Alarm 2 incident log
Press Alarm 1/Alarm 2 to access the incident log. Shown below is is an example
of the data provided. The incidents are listed in chronological order. Incidents are
identified by sample area and gas type. The log shows the status (Alarm 1 or Alarm
2) of the leak, the time and date it was initially detected (started) and the time and
date it cleared. The ACM 150 alarm status reset behavior is conditional; it depends
upon the acm.cnf setting of the "EnablePreWarn = No" variable, which has a default
setting of "No." When "EnablePreWarn = No," if a gas concentration drops to
normal below AL1 (Warn) setting, the current status is set to "O" = Normal = no AL1
and no AL2. This reading does not have to be 0.000, just no greater than the AL1
setting. When "EnablePreWarn = Yes," if a gas concentration drops to normal below
AL1 (Warn) setting but still shows a small fractional positive reading > 0.0 and the
previous status was AL1 or AL2 (Warn or Alarm), the current status is left as AL1
or AL2 as before. So if EnablePreWarn is set to Yes, the ACM 150 alarm system will
be returned to "alarm status = normal" if and only if the gas reading is absolutely =
0.000.
