38 Instruction 3015-4275
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.
