3.6 Function Tests
Alarm Test
 Turn on the device. Verify that:
- alarm LEDs flash
- horn sounds briefly
- vibrating alarm triggers briefly.
3.7 Bump Test
This test quickly confirms that the gas sensors are functioning. Perform a full cali-
bration periodically to ensure accuracy and immediately if the device fails the
Bump Test. The Bump Test can be performed using the procedure below or auto-
matically using the GALAXY Test Stand.
Equipment
See accessory section for ordering information for these components.
- Calibration Check Gas Cylinder
See Section 5.4 for calibration gas target values and appropriate MSA calibra-
tion gas cylinders.
- Demand Flow Regulator[s]
- Tubing appropriate for the gases to be tested
- Kits containing tubing and regulators suitable for reactive and non-reactive gas-
es are available from MSA.
Performing a Bump Test
For ALTAIR 5X IR devices with combustible % Vol IR sensors, the following gas
levels should not be exceeded when used for daily Bump Tests:
Attention!
Perform a Bump Test before each day’s use to verify proper device
operation. Failure to perform this test can result in serious personal inju-
ry or death.
The Galaxy cannot test Chlorine Dioxide, % Vol Butane, % Vol Propane
and % Vol Methane sensors.
For these sensors, use this Bump Test procedure.
