1.4.7 Fault detection
IQ Force software includes a number of additional alarms designed to ensure the proper operation of the instrument. When the IQ Force detects that an electronic fault or failure condition has occurred, the proper audible and visible alarms are activated and an explanatory message or message code is displayed. See Appendix F for error codes, associated explanations and courses of action.
The IQ Force is designed to detect potentially life threatening
atmospheric conditions. Any alarm condition should betaken
seriously. The safest course of action is to immediately leave the
affected area, and return only after further testing determines
that the area is once again safe for entry.
1.5 Other electronic safeguards
Each time the detector is turned on, the IQ Force automatically tests the LED alarm light, audible alarm, vibrating alarm, and internal memory. The battery

is monitored continuously for proper voltage. The IQ Force also monitors the connection of sensors that are currently installed. The detection of any electronic faults causes the activation of the audible, vibrating and visible alarms and causes the display of the appropriate explanatory message.
1.5.1 Heartbeat
At the center of the display is a heart symbol that will blink every few seconds to show that the instrument is functioning normally.
