5. General
5.1 Control unit (picture 1)
The control unit emits a notification via dry-contact output and by sound (unless muted)
when the sensor detects fast-paced movement (frequency 3–20Hz) in the bed for the
duration of the preset time (10, 13, 16 or 20 sec.).
The control unit operates with 2 pcs AA size 1.5 V alkaline batteries. An external power
supply is available. Do not use any power supply other than that provided by Abilia. (see
chapter Technical Specifications for details) (picture 2). In the event of a power failure, two
high-quality 1.5V AA alkaline batteries can be used as an emergency power supply. Do
not use any rechargeable batteries or lithiumion batteries! Rechargeable or lithium-ion
batteries carry the risk of melting, ruining the device and causing possible danger to the
user.
The control unit has an input connector for the bed sensor (X3) and power supply (X1).
The device also has a connector (X2) to transfer the notification via an external system
e.g. a nurse call system or a personal emergency phone.
Next to the input connector, there is a push button (SW1) that can be used to acknowledge
a notification or as an on/off switch. (picture 3)
The control unit has 8 DIP switches (picture 4) to select the settings and a rotary switch to
adjust the sensitivity of the device. (picture 5)
5.2 Bed sensor (picture 6)
The bed sensor produces a millivolt alternating current when detecting movement. The
control unit calculates the frequency and scale of the movement from this signal and, on
this basis, detects possible tonic-clonic seizure. Micro-movement from heartbeat allow the
device to detect the person's presence.
