1. GENERAL INFORMATION

Intended Use

The Emfit SafeBed™ Bed Occupancy Monitor (device model D-1070-2G and sensor model L-4060SL) is intended to be used for
monitoring bed occupancy and giving notification when no occupancy is detected. The product consists of a bed sensor and a
control unit. The control unit has an audible notification sound and a dry-contact output for connecting it to the other parts 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 respiratory 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 processes a low voltage (from about 1 mV up to about 1 V),
high impedance signal from the dynamic, quasi-piezoelectric type (i.e. self­biased) flexible film-like sensor.

The control unit operates with 2 pcs AA size 1.5 V alkaline batteries. An
optional AC adapter is available (5 VDC). AC ADAPTERS OTHER THAN
ORIGINAL ACCESSORIES FROM EMFIT MUST NOT BE USED.

The control unit has input connectors for the sensor (marked as X3) and
optional AC adapter (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 optocoupler. A reset switch for turning off the notification sound is
to the right of the sensor input (marked as SW1).

Inside the device there is a place for 2 pcs AA size 1.5 V alkaline batteries, and mini-switches (DIP and rotary) for program
settings.

Under Mattress Bed Sensor

The Emfit under mattress bed sensor model L-4060SL is a quasi­piezoelectric, dynamic sensor that has no embedded wires or switches.
This specially formulated plastic sheet sensor is placed beneath the
mattress, crosswise to the bed, below the chest area.

The sensor produces signals from even the slightest micro-movements
created when a person 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 optocoupler. There are no particular
size or weight limitations, but sensitivity and ability to recognize user’s
micro-movements and thus presence in bed need to be tested in each
case.

- Bed sensor

- Wall mounting clip

- 2 screws

- 2 locking anchors

3. BEFORE USE SELECT THE RIGHT DIP SWITCH SETTINGS

Inside the device there is a DIP switch with 8 small
switches. These are used for various program settings.

See the following table and set up the switches for
your preferred way.

To open the device cover, see the picture on right.

Open the cover by
lifting from one side

Table of DIP Switch Settings

Switch # OFF (down) ON (up)

#1 Notification time delay setting, see next chapter Notification time delay setting, see next chapter

#2 Notification time delay setting, see next chapter Notification time delay setting, see next chapter

#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 pad

Increased sensitivity for noticing micro-movements.
Recommended use only when sensor needs to be
installed below spring mattress (no mattress pad in
use). NOTE! Consumes more power and shortens
battery life! Blue light blinks slightly faster.

#5 Dry-contact output is pulse mode (about 1 sec

pulse)

Dry-contact output is constant type. Use only when
necessary by other system to be connected with. Not to
be used with batteries! Only with optional power supply
due increased power consumption.

#6 Power switch function at SW1 is enabled (device

can be shut down and turned on by pressing SW1
for about 3 seconds)

Power switch function at SW1 disabled (device is
always on).

Setting the Notification Sound Volume

The notification sound is useful only when caregiver is in close proximity 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 (up) OFF (down)

Quiet OFF (down) ON (up)

No sound / mute ON (up) ON (up)

The sound stops when both the reset switch is pressed and when the event is over. In case of person’s absence from the bed,
the sound will stop once person has returned or reset is pressed.

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. SETTING THE SENSITIVITY

Sensitivity can be adjusted with 10 position rotary switch inside. Factory default setting is the
pointer pointing to #3. In case device does not notice individual’s micro-movements, adjust
sensitivity higher by turning the pointer clock-wise one position per time. If the device notices

5

movements even though no one is in bed, lower sensitivity by turning the screw counter-clockwise one position per time. Always
test after every change before taking into use.

5. INSTALLING THE BED SENSOR 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.

6. CONNECTORS AND WIRING

Connectors are marked with X1, X2 and X3. These are:

X1 - Power supply connector. Use only GlobTek Inc. power supply, model no:

accessory from Emfit.

X2 - Aux connector for connecting the device to some other system (cable not

included) for transferring the notification via a dry-contact optocoupler.
DRY-CONTACT OUTPUT OF THE X2 (AUX) CONNECTOR CAN ONLY BE
CONNECTED TO A SYSTEM SAFETY VOLTAGE INPUT WITH MAX VOLTAGE
BELOW 25V (AC) / 60V (DC), WHERE BOTH POLES HAVE BEEN SEPARATED
FROM THE ELECTRICAL NETWORK (SO CALLED FLOATING APPLIED PART).
MAX LOAD CURRENT 100 mA!

X3 - Sensor connector (use only Emfit bed sensor model L-4060SL)

Connect the under mattress sensor, optional AC adapter and possible connection wire to other system as follows:

Connect the sensor wire plug to the
control unit X3 marked connector.

If you need to connect the dry­contact output to another system,
plug the suitable connection wire to
the X2 marked connector

Connect the optional AC adapter
cord to the X1 marked connector
