PRODUCT BULLETIN
Acknowledging Alarms on Multi-Zone Monitors
Bacharach Multi-Zone monitors handle alarms in two ways, Automatic and
Manual
1) If you are using a third-party EMS, choose "Automatic". This will allow the unit
to reset once alarm conditions clear.
2) If you are utilizing the lights and relays on the unit to alert you of leaks, choose
"Manual". Manual is the default setting on your monitor. This setting will force a
manual acknowledgement on the monitor before the unit resets. This is
important if, for instance, the leak only shows during an unattended time, or at
night. You would never know you had a leak unless you made a habit of checking the alarm log
history regularly.
Changing the Alarm Acknowledge Mode
This function programs the relays in the unit for latching or non-latching operation.
AUTO (Non-latching) - Alarm relay will automatically de-energize when the gas level drops
below its alarm point.
MANUAL (Latching) - Alarm relay remains energized, and will not release until the alarm
condition has been manually acknowledged.
Alarm Acknowledge Mode selection
This function programs the relays in the unit for latching or non-latching operation.
1. Highlight the "ALM ACK MODE" box and press the ENTER key to adjust the setting.
Use the UP/DOWN cursor keys to toggle between settings.
2. Press ENTER to accept the new entry or ESC to revert to the previous setting.
