OVER maTTRESS, uNDER maTTRESS aND ChaiR PaD SENSORS
in addition to steps 1-5 steps on the previous page:
1. Test several places along the
entire surface of the sensor by
applying and removing pressure
to make sure the alarm activates
when pressure is removed from
the sensor/mattress (figs. 21a, b, c),
when you unfasten the chair belt
sensor (fig. 23) or activate the PiR
sensor (fig. 24). if the alarm and/or
sensor do not function properly, remove the alarm and sensor from service and replace them with
a properly functioning alarm and/or sensor. DO NOT use the alarm or sensor if it does not activate
each time weight is removed from the sensor, the chair belt sensor is unfastened, or the PiR sensor
is activated.
2. make sure sensor pad air intake (“neck” of over mattress or chair sensor
pad) is clear and not blocked (fig. 22). air must flow freely in and out of
sensor for alarm to function. make sure liquid does not enter at “neck”
of sensor pad, as this will damage sensor. if needed, use an incontinence
pad to protect sensor from urine or other liquids.
3. make sure sensor lays FlaT on chair or bed surface, directly under
patient’s weight, and that sensor cord is not folded back under the pad.
4. Check that there is no risk that chair sensor pad will be trapped in a
“hammocking” chair seat. To reduce this risk, place a foundation cushion on seat under sensor (see Posey
catalog no. 7110C Semi-Rigid Wheelchair Foundation).
5. 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.
ChaiR BElT SENSORS
in addition to steps 1-5 on the previous page (FOR SaFE uSE iN all
SENSOR mODES), press self-release button to unfasten buckle, or
separate hook and loop straps (fig. 23). alarm should activate each time
you do this.
PiR SENSORS
in addition to steps 1-5 on the previous page (FOR SaFE uSE iN all
SENSOR mODES), move your hand or arm into range of PiR beam (fig.
24). alarm should sound and/or the Nurse Call interface (if in use)
should activate each time you do this.
