Before You BeginThe Posey Passive Infrared (PIR) Sensor is a device designed to work with

Posey Alarms that are sensor activated. The Posey PIR Sensor monitor system is intended to help prevent falls and/or patient wandering in settings where continuous surveillance of admissions is not possible. Each system consists of the PIR Sensor and a Posey Alarm (Alarm sold separately). As the patient moves into the operating range of the infrared beam, the alarm is activated.

Indications (these may include):• Individuals with diminished cognitive or mobility skills, i.e. frail,

disabled or senile patients, or those with neurological defi cits.

• Patients receiving medications that may cause disorientation, drowsiness, dizziness or frequent urination, (i.e. diuretics).

• Any admission (new or existing) with a history of falling.

• Individuals who are restless or prone to get up in the middle of the night, i.e. incontinence and those with nocturnal voiding patterns.

• Any new admission where the patient is assessed to be a fall risk, i.e. the elderly, patients receiving medications, or those with functional or cognitive defi cits.

• Patients requiring mandatory bed rest.

Contraindications:The Passive Infrared (PIR) Sensor should never be used as a sole surveillance device for agitated, combative or

suicidal admissions, or for those at an extreme physical risk for a life-threatening fall. In these cases, the PIR Sensor

should be used with a more intensive fall prevention measure.

Response:Each facility should determine the appropriate protocol for responding to fall monitor alarms. This protocol

might include calling over the intercom, and telling the individual to wait for assistance and then sending staff imme-diately to the room. Be sure to put a notifi cation next to the room light at the nurses’ station to help identify high fall

risk patients. This will help the nursing staff respond immediately when the call signal is activated.

Nursing Surveillance:Each policy should address the frequency of visits by nursing staff to confi rm that the patient/resident is safe. In

addition, these visits should include periodic verifi cation that the PIR Sensor and the Alarm are functioning properly.

The Benefi ts of the Passive Infrared (PIR) SensorThe Posey Passive Infrared (PIR) Sensor provides a non-invasive means to monitor patient movement. Powered

by a 9-Volt battery or AC power, the PIR Sensor senses temperature change when a person moves into the operating range of the infrared beam, activating the Posey Alarm. Since the PIR Sensor senses temperature change rather than

motion, the chance of a false alarm is minimized. The PIR Sensor is compatible with any sensor activated Posey Alarm.

How the PIR Sensor WorksEach PIR Sensor is shipped to you with:

• PIR Sensor component• 9-Volt battery• AC Power Adapter with extension cord• Mounting Arm• Adhesive hook-and-loop (2 sets)• 24” Connection cable

InstructionsThe PIR Sensor is a temperature responsive sensor.

Once it has adjusted to the ambient room temperature,

it will trigger the alarm when sensing a change in

tem perature the instant a person moves into the

operating range of the beam. Since the PIR Sensor

senses a change in temperature rather than motion,

the chance of a false alarm is minimized.

To verify the PIR Sensor Alarm System is working

properly:

1. Using the cable supplied, plug the PIR Sensor into

the Posey Alarm (sold separately).

2. Make sure the LED lights on the PIR Sensor and

Posey Alarm are lit, indicating the units are “ON”.

3. Verify that the batteries are fresh. If you hear an

intermittent chirp coming from either the PIR

Sensor or the Alarm, the batteries are low and need

to be changed.

4. Check that the audible alarm on the Posey Alarm is

functioning properly by moving into the operating

range of the infrared beam.

5. Verify the nurse call interface, when used, is connected

properly to the Posey Alarm and activated when you

move into the operating range of the infrared beam.

6. Please refer to the alarm instruction manual for

additional instructions on the operation of the Posey

Alarm.

To avoid possible injury or death:Verify both systems are on and working properly before leaving a patient unattended. Do not use the Posey PIR Sensor or Posey Alarm if the audible alarm does not sound or the nurse call system does not activate upon movement into the operating range. Replace batteries if the audible low battery warning sounds.

The Posey PIR Sensor is an electronic device. If the unit is

subjected to a severe mechanical shock, such as dropping

the unit, or is submerged in liquid, the unit may stop

functioning as designed. After each incident, you must

verify that the PIR Sensor and Posey Alarm are working

properly as outlined above.

Powering the SensorThe PIR Sensor can be powered by either one 9-Volt bat-

tery or by AC power using the included adapter. When

using the 9-Volt battery, the estimated battery life is ap-

proximately 30 days. Actual battery life is dependent on

the quality of battery and the frequency of alarm.

Inserting/Changing the Battery:1. Press down on the arrow, slide the battery door off

and set aside (fi g. 1).

2. Remove the battery from the battery compartment.

3. Position your thumb under the wires on the terminal

cap and push up to disconnect (fi g. 2).

4. Connect the terminal cap to a new battery and insert

the battery into the battery compartment.

5. Slide the battery door closed.

Connecting the Power Adapter:1. The AC power adapter has a pre-connected 6 ft. cord.

A 6 ft. extension cord is also included.

2. Connect the AC power adapter to the PIR Sensor

(fi g. 3).

3. Plug the other end into the wall outlet.

4. If additional cord length is needed, disconnect the

AC power adapter from the PIR Sensor and connect

the power adapter to the extension cord (fi g. 4).

5. Connect the extension cord to the PIR Sensor.

Fig. 5 Fig. 6

NOTE: Plugging in the AC power adapter will bypass

the battery power. If the facility loses power, the

PIR Sensor will NOT revert to battery power.

Installing the PIR Sensor and connecting to a Posey AlarmThe Posey PIR Sensor can be used on a bed to alert staff

of unassisted bed exits, or on a doorway to monitor

unauthorized entry or exits.

Bed Mounting

1. Use the mounting arm (fi g. 5) to attach the PIR Sensor

to the footboard.

2. Choose a site on the outside of the footboard. The

mounting arm should extend beyond the width of

the footboard to allow the PIR beam to project along

the entire length of the bed.

3. Clean the site with an alcohol wipe and let it dry.

4. Attach self adhesive loop (soft) patch by peeling of

backing and pressing into place on the desired

location (fi g. 6).

5. Attach the mounting arm to the footboard (fi g. 7)

6. Attach the PIR Sensor to the mounting arm so the

beam is directed parallel to the bed, as shown in

fi g. 8.

7. Mount the selected Posey Alarm to the footboard.

The KeepSafe alarm can be attached to the PIR

mounting arm, as shown in fi g. 9. Other Posey Alarms

should be attached to the footboard with the

appropriate bed bracket (fi g. 10).
