Responding to Alarms
This section describes response to gas, over range, battery, sensor failure, LIMITED HC GAS
LIST, clock failure, system failure, man down, and panic alarms.
Responding to Gas Alarms
1. Determine which gas alarm has been activated.
2. Follow your established procedure for an increasing gas condition or a decreasing oxygen
condition.
3. Reset the alarm as necessary or allowed.
a. If LATCHING is set to ON (factory setting) in Maintenance Mode, the gas reading must
fall below (or rise above for an oxygen low alarm) an alarm setting before you can reset
the alarm condition using POWER MODE or AIR.
b. If Password Protection is turned On (factory setting is Off) using the SDM-3R PC
program, you must press POWER MODE and AIR at the same time and then enter a user-
set password to reset an alarm condition. When the password screen appears, adjust each
digit with the AIR button and press and release the POWER MODE button to move on to
the next digit. Once the password is entered, the alarm condition resets.
