The SecNurse is a bed occupancy detector for beds in nursing homes and elderly care envi-
ronments. An alarm is sent when the patient leaves the bed, or leaves the bed and does
not return within a specified time.
The sensor is based on vision technology. With this technology the sensor can see and
interpret situations. The greatest advantage with this technology is that the sensor, to a
high extent, can be adjusted to the patient’s needs. Other advantages are longer pro-
duct lifetime than comparable products and no need for hygienical maintenance, due to
the fact that the sensor does not demand physical contact.
Another advantage of the SecNurse is the adjustable sensitivity. The sensor can either send
an alarm when the patient leaves the bed or as soon as the patient sits on the bed edge.
In addition to this User´s Guide there is a shortguide with the most common functions.
Important!
The sensor is a technical aid, which substantially increases the efficiency per patient at regu-
lar supervision. However, it is only a complement to regular supervision, the SecNurse is not
intended to replace ordinary supervision of the patient by the nursing staff. During certain situ-
ations, the sensor might fail to detect that the patient leaves the bed, incorrect usage or incor-
rect mounting substantially increases the risk. All staff and other concerned should be clearly
informed about these matters. As a result of this Optex can therefore not be responsible for
direct or indirect injuries that arise in connection with or as a result of using the sensor.

The installation procedure consists of five steps:
1. Mount the sensor on the wall
2. Connect the sensor
3. Configure the bed zone
4. Set timer and sensitivity settings
5. Make a functional test
Mounting instructions
In order to get the sensor to work in a satisfying way, it must be mounted correctly.
The first step in the mounting procedure is to attach the mounting bracket on the wall.
Thereafter the sensor can be easily snapped on the bracket. The design of the bracket
allows you to remove the sensor from the bracket, in order to move the sensor from one
bed to another.
The SecNurse can be mount on two different heights. When the bed zone has been con-
figured, the sensor will automatically recognize which mounting height is being used.
At both mounting positions it is important that the sensor is mounted horizontally, above
the middle of the bed and on the wall. This is important for a correct detection angle.
Large pieces of furniture should not be placed close to the bed, since this will affect the
detection performance negatively.
3. Installation
IMPORTANT!
The installation must be made in a correct way in
order to get proper functionality.
IMPORTANT!
Always use the mounting bracket for optimal
performance.

3. Installation
Mount the sensor on the wall
The sensor must be mounted either above the head end of the bed or above the long side
of the bed, according to the images below.
In both cases the sensor should be placed above the centre of the bed side.
Above the head end of the bed Above the long side of the bed
If it is possible to install the sensor in both ways, the long side mounting should be pre-
ferred if a lifting pole is mounted on the bed or if the detection sensitivity setting should
be set to detect the patient on the bed edge, see chapter 4, Using the sensor.
Mounting position 1. Above the head end of the bed
1a. If there is not a lifting pole mounted on the bed,
the sensor should be placed 180 cm above the floor,
distance A in the figure.
b. If there is a lifting pole mounted on the bed, the
sensor should be placed 200 cm above the floor and
the vertical distance between sensor and lifting pole
must be at least 40 cm, distance B in the figure.
Note! When the black mark on the sensor cord
reaches the floor, the mounting height is 200 cm
and when the red mark reaches the floor, the
mounting height is 180 cm.
2 Place the bed close to the wall with the sensor
placed just above the middle of the bed, according
to the figure to the left.

Fasten the mounting bracket
Fasten the mounting bracket on the wall, thereafter the sensor can easily be snapped on
the bracket.

B
Mounting position 2. Above the long side of the bed
Fasten the mounting bracket on the wall.
It is very important that the mounting bracket is placed horizon-
tally.
Place the sensor in the two notches of the mounting
bracket.
Gently press the sensor downwards.
This procedure is reversible, which makes the sensor easy to
move to another bed.
1. Mount the sensor 180 cm above the
floor, distance A. Normally the sensor
should be placed above the middle of the
long side, but if a lifting pole is mounted
on the bed, the sensor should be 10-20
cm closer the foot end of the bed, dis-
tance B.
Note! When the red mark on the sensor
cord reaches the floor, the mounting
height is 180 cm.
2. Place the bed close to the wall with the
sensor placed just above the middle of
the bed, or 10-20 cm closer to the foot
end if there is a lifting pole on the bed.
- 11 -
3. Installation
Consider the following
The sensor automatically calculates different distances in order to decide whether the
person leaves his or her bed or not. If the sensor is mounted in an incorrect way these
distances will be wrong, which will disturb the detection performance and cause false
alarms.
Example. If the sensor is mounted lower than 180 cm the sensor will apprehend the bed
to be much larger than it really is. The person leaving the bed will be apprehended to be
enormous, and will for this reason be sorted away as an absurdity.
- Pieces of furniture and light sources may disturb the performance
NOTE!
Different systems may have the same type of contact,
but a different type of pin-out.
In order to detect the patient leaving the bed,
it is important that there are no pieces of furni-
ture or other large objects blocking the person
from the sensor. Even pieces of furniture only
covering the person partly may effect the
performance. Light sources placed close to the
sensor may also effect the sensor performance.
Connect the sensor
Different alarm systems have different input contacts. In order to make it as easy as pos-
sible to connect the sensor to the alarm system, the sensor can be delivered with different
contacts for different systems, which makes it possible to connect the sensor directly to
every alarm system. (see page 5 for more details).

Out of bed mode
Relay 1 is activated when the patient leaves the bed (or after the countdown timer is
started, depending on the sensitivity/timer). If the patient returns to the bed before the
timer has elapsed the sensor will return to its normal mode, no alarm is sent. In case of an
alarm, relay 1 is activated for 2 seconds.
Relay 2 is activated when the patient is leaving the bed and turned off when the patient
returns to bed again.
Armed mode
Relay 1 is activated when the patient leaves the bed (or after the countdown timer is
started, depending on the sensitivity/timer). If the patient returns to the bed before the
timer has elapsed the sensor will return to its normal mode, no alarm is sent. In case of an
alarm, relay 1 is activated for 2 seconds.
Relay 2 is activated when the sensor is turned on by the remote control (armed mode) and
turned off when the sensor is turned off again with the remote control. For instance as a
sabotage contact.

Configure the detection zone
In order to detect correctly, the sensor needs to know the correct position of the bed. By
“marking” the two far corners of the bed with the remote control, the sensor receives
this information. After marking the bed, the sensor starts to calculate the surrounding
detection zones. Each time the sensor or bed has been moved the procedure has to be
repeated.
Configuration position 1. Above the head end of the bed

Direct the remote control towards the
sensor and press the room/foot button if the
patient can leave the bed on this side. If the
patient cannot leave the bed on this side
press the wall/head button.
Keep the button pressed down as long as
the red LED flashes (the sensor is learning
the position).
When the sensor has learned the right
position, the LED’s on the sensor indicate as

Adjust the sensor to the individual
Different patients have different needs. Some patients run a large risk of injury and should
not walk unattended, while other patients can manage to take care of themselves. The
SecNurse can be configured to fulfil the demands of these patients individually. The con-
figuration can be made by adjusting the timer and sensitivity setting.
By increasing the timer the patient gets the possibility to get up from the bed for a short
while, for example to go to the bathroom, without an alarm being sent. If the patient
does return to the bed before the timer has elapsed, no alarm will be sent. In this way
the patient gets increased privacy and a reduced number of false alarms benefits both the
patient and the caregiver. The sensor normally detects when the patient leaves the bed. If
an earlier alarm is required, the detection sensitivity can be set to send an alarm as soon as
the patient sits on the bed edge.
Standard there is a second output contact (out of bed mode) available which can be used
according to the individual needs of a patient. For example to switch a light or to connect
to the existing nurse call system so the staff gets a notification that a patient has left the
bed but is not in an alarm situation.
A second software function* ”the armed mode” is available. In some situations it is
needed that the SecNurse offers a contact (armed mode) to the nurse call system so that
the nurse call system knows the sensor is turned on.
Set the timer and sensitivity
There are two options to adjust the sensor to the patient:
1. Set the timer
When the patient leaves the bed the timer is started, if the patient has not returned within
the selected time frame an alarm will be sent.
Example. If the timer is set on 20 minutes the patient can leave the bed to go to the toilet
without an alarm being sent, but if something happens and she/he does not return to the
bed after 20 minutes an alarm is sent.
*No additional charges, but please mention the software type on your order.

Test
In order to confirm the installation a functional test should be made.
It is important that the person who performs the test is alone in the room, since the
sensor is developed for situations when only one person is present.
Please perform the functional test as described on page 18.
If the test does not turn out well, the sensor has to be restarted and the bed zone recon-
figured. See further chapter 7, Troubleshooting.

If a direct alarm is required (0 min.) there
are two sensitivity settings:
An alarm is sent when a person leaves the
bed or an alarm is sent when a person sits
on the edge of the bed. Press the - button
until the yellow and red LEDs are on.
If a time sequence is allowed press the +
button to increase the timer or the - button
to decrease the timer. After each time
the button has been pressed the current
configuration is shown by the LEDs. Please
refer to the picture as shown on the left.
IMPORTANT!
The timer does not take possible delay in
the internal alarm system into account.

Functional test
1. Turn off the sensor and set the timer to 3 min.
2. Lay down in bed.
3. Turn on the sensor (press the ON/OFF button) Green LED is turned on.
4. Wait until the light intensity of the green LED decreases (this takes about 15 sec).
5. Leave the bed. When the sensor has detected you, the red LED starts to flash.
6. Lay down in bed again. When the sensor has registered that you are back in bed
the red LED stops to flash.
7. Repeat point 2 to 6, if possible, for the other side of the bed.
8. Repeat point 2 to 5 but this time make sure that you do not return to the bed.
9. The sensor will send an alarm to the internal alarm system after 3 minutes. When
an alarm has been sent, the red LED will change from flashing to solid red.
10. Turn off the sensor with the ON/OF button (the green LED is turned off).
11. Set the timer to 0 min with increased sensitivity (sitting on the edge of the bed
posi tion on the remote control.
12. Lay down in bed. Press the ON/OFF button.
13. Wait until the light intensity of the green LED decreases (this takes about 15 sec).
14. Sit down on the bed edge.
15. Make sure that the alarm is sent.
16. Turn off the sensor.
17. The functional test is finished. Note! It is advised to register the funcitonal tests in
a log-book.
- 19 -
4. Using the sensor
Activate and deactivate the sensor
The sensor is activated by directing the remote control towards the sensor and pressing
the red ON/OFF button. When the sensor is activated the green LED is lit.
The sensor should be activated
after the patient has been
helped to bed, right before the
caregiver leaves the room.
In order to give the caregiver
a chance to leave the room
without triggering a false alarm
there is a delay of 10 seconds
before the sensor is activated.
The sensor should be deac-
tivated when the caregiver
enters the room. Otherwise the
sensor will be activated and
trigger a false alarm. Therefor
it is advised to have the remote
control near the entrance of the
room.
Deactivate the sensor before helping the patient.
Otherwise the caregiver will trigger a false alarm.
The sensor is activated by pressing the red button.
When the sensor is activated, the green LED is lit.
Remember!
When the sensor is active a green LED is lit.

An alarm is sent
The countdown of the timer (see
chapter 3) is started when the
patient leaves the bed. The red
LED flashes during the count-
down.
If the patient returns to the bed
before the timer has elapsed the
sensor will return to its normal
mode, the red LED will stop
flashing and no alarm is sent.
However, if the patient does not
return to the bed and the time
elapses, an alarm is sent and the
red LED changes from flashing
to solid.
When the patient leaves the bed a countdown is started.
If the patient has not returned to the bed before the
time has elapsed an alarm is sent.
NOTE!
As long as the red led is blinking, the “out of bed
mode” is active.
