Troubleshooting Guide
(Continued)
Problem: intermittent alarm while the patient is in a bed or chair (see pages 19-23).
Solution: • Check that sensor cord and RJ11 plug are clean and undamaged. Check plug connection to alarm.
• Check sensor pad for creases or damage to vinyl cover.
• Check that sensor pad is directly under patient’s weight.
• Is the sensor getting caught in “hammocking” wheelchair seat? If so, place a foundation
cushion on seat, under sensor (see Posey catalog no. 7110C Semi-Rigid Wheelchair
Foundation).
• Make sure sensor cord is not folded back under pad.
• Make sure sensor pad air intake (“neck” of over mattress or chair sensor pad) is clear and not
blocked. Air must flow freely in and out of sensor.
• Try a new sensor if intermittent alarm can not be fixed.
• Make sure mattress continues to make contact with the sensor and will activate the alarm
when pressure is removed, even if the head or foot of the bed is articulated.
• Apply pressure to sensor in several areas to check that alarm activates (see page 20).
• Ensure batteries are not corroded (see page 8).
Problem: No alarm when patient exits bed or chair (see pages 19-23).
Solution: • Make sure alarm is ON (monitoring indicator LED is flashing green).
• Check batteries. If needed, insert four (4) new “AAA” alkaline batteries. DO NOT mix old and
new batteries, or different brands of batteries.
Chair Pad Sensor
• Make sure sensor cord is not folded back under pad.
• Make sure sensor pad air intake (“neck” of chair sensor pad) is clear and not blocked. Air
must flow freely in and out of the sensor.
• Check that there is no weight in the chair such as a box, bag or book.
• Check seating/positioning aides. A heavy wheelchair cushion may prevent alarm from
alarming. Try a different position for the sensor pad, such as on top of the cushion.
• Is the sensor getting caught in “hammocking” wheelchair seat? If so, place a foundation
cushion on seat, under sensor (see Posey catalog no. 7110C Semi-Rigid Wheelchair
Foundation).
• Try a new sensor if alarm does not sound.
Over/Under Mattress Sensors
• Check that all connections are tight and properly plugged into the alarm.
• Check that there is no weight on the mattress such as a box, bag or book.
• Check that the correct side of the bed sensor pad is “UP” under the mattress.
• Mattress may be too heavy for an under mattress sensor. Many older mattresses are very
heavy and will not allow the sensor pad to activate the alarm. You may need an over
mattress sensor.
• When the patient lies down they may not be making contact with the sensor to activate
monitoring. Try a different position for the sensor pad. Most patient weight is normally
under buttocks.
Chair Belt Sensor
• Check that all connections are tight and properly plugged into the alarm.
