Location

This is the name you assign to the AGM300 to identify its location. It may have up to 12 alphanumeric characters.

1.Press the LOCATION key to modify the setting.

2.Use the LEFT/RIGHT cursor keys to move across the entry field and the UP/DOWN cursor keys to modify the individual characters.

3.Press ENTER to accept the new entry or QUIT to revert to the previous setting.

Number of Zones Installed

IMPORTANT: Do not change the number of zones to deactivate excess zones. Instead, go to the individual zone that you wish to disable and set its distance to zero (refer to Navigating to the 1st Zone Setup Screen on Page 41). The monitor will perform a self-check on power-up, and if the number of zones detected does not agree with the number of zones installed a fault will occur.

1.Press the NUM ZONES INSTALLED key to adjust the setting.

2.Use the UP/DOWN cursor keys to modify the number.

3.Press ENTER to accept the new number or QUIT to revert to the previous setting.

NOTE: The AGM300 auto setting detects the number of zones present on power-up. DO NOT PLUG ANY ZONES. Plugging a zone will give the monitor a false indication during power up. The number detected on power up is the default value for this parameter.

Alarm Ack Mode

This function programs the relays in the AGM unit for latching or non-latching operation.

1.Press the ALARM ACK MODE key to adjust the setting.

2.Use the UP/DOWN cursor keys to toggle between settings.

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. Refer to Acknowledging Alarms on Page 52.) 3. Press ENTER to accept the new entry or QUIT to revert to the previous setting.

Audible Alarm

This parameter selects the function of the AGM300’s internal audible alarm device.

1.Press the AUDIBLE ALARM key to adjust the setting.

2.Use the UP/DOWN cursor keys to select unused, monitor on, evacuate, spill, leak, fault, or alarm.

3.Press ENTER to accept the new entry or QUIT to revert to the previous setting.

Zone Hold Time

Sets the length of time a zone will be monitored when the zone hold feature is actuated (see Zone Hold Mode on Page 45). The default is 15 minutes. This parameter can be set to any value between 1 and 999 minutes.

1.Press the ZONE HOLD MINUTES key to adjust this setting.

2.Use the LEFT/RIGHT cursor keys to move across the entry field and the UP/DOWN cursor keys to modify the individual numbers.

3.Press ENTER to accept the new entry or QUIT to revert to the previous setting.

Detection Limit

This is essentially a squelch setting that instructs the instrument to interpret PPM readings below the designated level as 0. You can set this value from 1 to 99 PPM.

1.Press the DETECTION LIMIT key to adjust this setting.

2.Use the UP/DOWN cursor keys to modify the setting.

3.Press ENTER to accept the new entry or QUIT to revert to the previous setting.
