Functionality
The secure wandering system is a system which allows
any potential escape attempts by confused patients to
be controlled.
Each exit under surveillance is fitted with a standalone
controller which alerts staff when a person wearing
a special wristband tries to go through it. In the event
that there are no supervisory staff near the exit, this
information can be transmitted to the BUS/SCS nurse
call unit using a door unit Cat. No. 0 766 06 configured
for this function. This way nurses are immediately
alerted to the escape and which door they have
gonethrough.
The system can operate using two modes:
• Surveillance mode: An alarm is activated when the
wearer of a wristband is close to the exit and this exit is
open.
• Intruder mode: An alarm is activated when an exit
isopened.
Switching from one mode to the other can be done
manually by entering a special code into the controller
keypad or by closing a clock contact.
The staff have a chaperone code which allows a
wristband wearer to be let through an exit under
surveillance without triggering an alarm.
Two control outputs allow:
• The exit to be locked once a wristband is detected
in the vicinity (provide an electromagnetic lock or an
electric door release).
• An audible or illuminated warning signal to be
triggered when an escape alarm is activated.

Situated close to the exit door, this controller is the
heart of the system.
All auxiliary elements are connected to it.
A 12-button keypad is used to configure it and
activate special functions (mode changes, alarm
acknowledgement, etc).
Buzzer and LEDs act as a warning if an escape
is detected. The buzzer makes a different sound
depending on the type of alarm (chaperone or fault).
The indicators show the system status simultaneously.
It can be suppressed.
The controller has a built-in antenna and can retrieve
information from the antenna Cat. No 0 766 21 and
door contact Cat. No. 0 431 00.
Depending on its usage mode, the controller:
- Buzzes and flashes
- Can lock the door if it has the necessary fitting
(electromagnetic lock, door release)
- Can trigger a nurse call if connected to the door unit
- Can send a message to the DECT
When the door is locked, it can be unlocked using
special codes.
The coded keypad picks up the wristband signal when
a resident passes through a predefined door.
Requires a modular 12 V=power supply
(Cat.No.4131 05).
Indicates that a door has been crossed by a resident fitted with a wristband Cat. No. 0 766 20.
Works with door unit Cat. No. 0 766 06 configured for secure wandering which allows acknowledgement and
feedback to the Legrand SCS nurse call unit system.

Used in the case of wide doors, double doors, placed as close to the exit as possible, ideally 50 cm from the
ground, opposite the controller. This antenna picks up the radio signal from a wristband Cat. No. 0 766 20 and
informs the controller Cat. No. 0 766 22.
The detection radius (around 1 to 15 m) can be set easily using a screwdriver.
A green indicator light indicates that the antenna power is on.
A red indicator light flashes when a wristband is in the detection zone (see setting the antenna).
The antenna activity is permanently checked by the controller.

Wristband Cat. No. 0 766 20
Worn on the wrist or the ankle, this waterproof wristband is fitted with an eyelet fastening preventing it from being
taken off by the person under surveillance.
These wristbands are made of anti-allergy plastic which can be in continuous contact with the skin.
The battery has an expected lifetime of more than a year (although replacing the batteries annually is recommended).
The IP 67 protection allows residents to take showers.
The wristbands can also be cleaned by placing them in an alcohol bath for 5 minutes.
They must be removed in the following cases:
- If they are faulty or the battery is dead
- When the resident leaves
- When the resident undergoes an MRI (magnetic resonance imaging) scan
Etc
To remove the wristband, cut it with a pair of round-end scissors.
When a wristband is immobile it switches to low-consumption mode. This can increase the standalone capacity of
the battery to a maximum of 4 years when stored.
Once wristband movement is detected, it switches immediately to operational mode.

• IP 55 - IK 08
• Anti-allergy
• Frequency: 869.85 MHz
• Tx: 869.85 MHz - Rx: 446.525 MHz

EXAMPLE OF INSTALLATION
The diagram below represents a typical installation for a standalone system (i.e. not connected to the door unit
Cat. No. 0 766 06 of the nurse call unit).
The controller with built-in antenna (15W30 -->) Cat. No. 0 766 22 is normally installed in the immediate vicinity of
the exit door, at a height which allows easy access to the keypad (1.20 m). Antenna Cat. No. 0 766 21 is installed
at a height of around 50 cm opposite the controller.
If the exit under surveillance is very wide (between 1 and 15 metres) a maximum of two extra antennae placed
on either side of the passageway can be connected to the same controller. This avoids having to set the antenna
sensitivity too high, which risks wristbands in neighbouring rooms being detected.
As with any radio-controlled system, the antenna position is crucial for wristband detection performance and
careful consideration must be given to where it is installed. Equally, wherever possible wristbands must be placed
in an identical manner on all residents under surveillance (for example, on the right wrist if the antenna is to their
right when they go through the exit).
The maximum wiring distance between antenna and controller is 200 metres.

Standalone installation (continued)
Outdoor installation:
The secure wandering system is not intended for outdoor installation. However, surveillance of this type of exit is
possible where the installation is adapted:
- The controller must always be installed indoors.
- The antenna boxes must be placed in weatherproof enclosures made from non-conductive materials (plastic,
PVC, etc).
- The enclosure must be protected from direct sunlight in order to avoid the risk of excessive temperatures inside
the box.
Selecting a door release or lock:
• Door release: flush-mounted installation
- Cable type (to controller 0 766 22): 2 x 1.5 mm2
- Cat. No. 0 408 95: undervoltage door release 12 V=- 600 mA. For operation at emergency exits
- Cat. No. 0 408 98: shunt trip door release 12 V±/=- 500 mA
• Electromagnetic lock: surface-mounted installation
- Cable type (to controller 0 766 22): 2 x 1.5 mm2
- Cat. No. 0 767 07: 300 kg lock
- Cat. No. 0 767 08: 500 kg lock
