1. GE ERAL I FORMATIO
Intended Use
The Emfit SafeBed™ Bed Occu ancy Monitor (device model D-1070-2G and sensor model L-4060SL) is intended to be used for
monitoring bed occu ancy and giving notification when no occu ancy is detected. The roduct consists of a bed sensor and a
control unit. The control unit has an audible notification sound and a dry-contact out ut for connecting it to the other arts of
the system.
Control Unit
The control unit D-1070-2G activates after it has noticed movements or
micro- movements, such as those caused by res iratory movements or the
heart beating, for over 40 seconds. Notification is triggered if no movements
or micro-movements are detected for at least 5 seconds.
The control unit rocesses a low voltage (from about 1 mV u to about 1 V),
high im edance signal from the dynamic, quasi- iezoelectric ty e (i.e. self-
biased) flexible film-like sensor.
The control unit o erates with 2 cs AA size 1.5 V alkaline batteries. An
o tional AC ada ter is available (5 VDC). AC ADAPTERS OTHER THAN
ORIGINAL ACCESSORIES FROM EMFIT MUST NOT BE USED.
The control unit has in ut connectors for the sensor (marked as X3) and
o tional AC ada ter (marked as X1). There is also a connector marked as X2
for connecting the device to other systems for transferring the notification via
dry-contact o tocou ler. A reset switch for turning off the notification sound is
to the right of the sensor in ut (marked as SW1).
Inside the device there is a lace for 2 cs AA size 1.5 V alkaline batteries, and mini-switches (DIP and rotary) for rogram
settings.
Under Mattress Bed Sensor
The Emfit under mattress bed sensor model L-4060SL is a quasi-
iezoelectric, dynamic sensor that has no embedded wires or switches.
This s ecially formulated lastic sheet sensor is laced beneath the
mattress, crosswise to the bed, below the chest area.
The sensor roduces signals from even the slightest micro-movements
created when a erson is in bed. When there is no movement, it
recognizes this as the individual being absent and it gives a notification
both by sound and via dry-contact o tocou ler. There are no articular
size or weight limitations, but sensitivity and ability to recognize user’s
micro-movements and thus resence in bed need to be tested in each
case.

3. BEFORE USE SELECT THE RIGHT DIP SWITCH SETTI GS
Inside the device there is a DIP switch with 8 small
switches. These are used for various rogram settings.
See the following table and set u the switches for
your referred way.

#1 Notification time delay setting, see next cha ter Notification time delay setting, see next cha ter
#2 Notification time delay setting, see next cha ter Notification time delay setting, see next cha ter
#3 Shortest notification time 5 seconds Shortest notification time 10 seconds
#4 Normal sensitivity for noticing micro-movements;
use when sensor is installed below foam mattress
or mattress ad
Increased sensitivity for noticing micro-movements.
Recommended use only when sensor needs to be
installed below s ring mattress (no mattress ad in
use). NOTE! Consumes more ower and shortens
battery life! Blue light blinks slightly faster.
#5 Dry-contact out ut is ulse mode (about 1 sec
ulse)
Dry-contact out ut is constant ty e. Use only when
necessary by other system to be connected with. Not to
be used with batteries! Only with o tional ower su ly
due increased ower consum tion.
#6 Power switch function at SW1 is enabled (device
can be shut down and turned on by ressing SW1
for about 3 seconds)
Power switch function at SW1 disabled (device is
always on).

Setting the otification Sound Volume
The notification sound is useful only when caregiver is in close roximity to the control unit. The volume can be adjusted at 4
levels: no sound, quiet, loud, and very loud.
Volume level Switch # 7 Switch #8
Very Loud OFF (down) OFF (down)
Loud ON (u ) OFF (down)
Quiet OFF (down) ON (u )
No sound / mute ON (u ) ON (u )
The sound sto s when both the reset switch is ressed and when the event is over. In case of erson’s absence from the bed,
the sound will sto once erson has returned or reset is ressed.
ALWAYS REMOVE BATTERIES AND UNPLUG THE AC ADAPTER (IF IN USE) BEFORE MAKING CHANGES TO THE DIP SWITCH
POSITIONS. OTHEWISE THE NEW SETTINGS WILL NOT TAKE EFFECT.
4. SETTI G THE SE SITIVITY
Sensitivity can be adjusted with 10 osition rotary switch inside. Factory default setting is the
ointer ointing to #3. In case device does not notice individual’s micro-movements, adjust
sensitivity higher by turning the ointer clock-wise one osition er time. If the device notices

5
movements even though no one is in bed, lower sensitivity by turning the screw counter-clockwise one osition er time. Always
test after every change before taking into use.
5. I STALLI G THE BED SE SOR BELOW MATTRESS
ALWAYS INSTALL THE SENSOR CROSSWISE TO THE BED AT THE POSITION BELOW THE
CHEST.
CHECK THE CORRECT PLACEMENT OF THE SENSOR AT LEAST ONCE A WEEK.
IF YOU USE THE SENSOR ON A SPRING MATTRESS, PLACE THE SENSOR BETWEEN THE
MATTRESS PAD AND THE SPRING MATTRESS!
IF THE BED HAS A SPRING MATTRESS, WITHOUT MATTRESS PAD, AND A BOX OR A SPRING
BOX BELOW SPRING MATTRESS, SENSOR CAN BE INSTALLED BETWEEN THE SPRING
MATTRESS AND THE BOX. IN THAT CASE INSTALL A DURABLE, 2-3 MM THICK PLASTIC OR
PLYWOOD SHEET ON TOP AND BELOW THE SENSOR TO AVOID THE SPRINGS DAMAGING
THE SENSOR. A THIN SOFT CUSHION BETWEEN THE SHEETS AND SENSOR IS PREFERRED.
SET DIP SWITCH #4 UP.
THE SENSOR MUST ALWAYS BE PLACED BENEATH A MATTRESS OR MATTRESS PAD. THE
SENSOR MUST NOT BE IN DIRECT CONTACT WITH A PERSON!
THE EMFIT BED SENSOR IS DESIGNED TO WITHSTAND USE BELOW A MATTRESS, AGAINST
A HARD BED BOTTOM FOR 4 – 5 YEARS OF USE. MANUFACTURER RECOMMENDS REPLACING IT AFTER 6 YEARS FROM
MANUFACTURING DATE OR AFTER 5 YEARS OF USE, WHICHEVER COMES FIRST.
WHEN USED ON TOP OF A SPRING MATTRESS, THE USE TIME IS MUCH SHORTER DUE TO MORE WEAR AND TEAR IS
CAUSED WHEN PERSON IS IN BED. THIS WEAR AND TEAR CAUSES THE SENSOR TO WRINKLE. WITH SPRING
MATTRESSES, A PERSON’S WEIGHT AND RESTLESSNESS CAN AFFECT THE USE TIME. THE ESTIMATED USE TIME IN A
SPRING MATTRESS BED IS 1–2 YEARS. IF USED IN SUCH CIRCUMSTANCES, MANUFACTURER RECOMMENDS REPLACING
THE SENSOR LATEST AFTER 3 YEARS OF USE. WARRANTY DOES NOT APPLY IF BED SENSOR IS DAMAGED DUE TO
NORMAL WEAR AND TEAR!
DO NOT USE WITH ANTI-DECUBITUS MATTRESS (USED FOR PREVENTING BED-SORES), WHERE AIR PRESSURE IS
CONTROLLED WITH COMPRESSOR.
