SYSTEM DESCRIPTION
Safety instructions
This product must be installed in accordance with the installation regulations and preferably by a qualified electrician. Incorrect installation and operation may lead to the risk of electric shock or fire. Read the instructions and consider the product's specific assembly location before carrying out the installation.
Do not open, remove, alter or modify the device unless this is specifically stated in the instructions. Legrand products must be opened and repaired exclusively by personnel trained and authorised by Legrand. Any unauthorised opening or repair voids all liability, replacement rights and warranties.
Only use Legrand brand accessories.
Operating environment
- This device complies with the directives related to exposure to radioelectric frequencies when used under the normal conditions described in the user manual. Follow the installation instructions described in the manual.
- Depending on the configuration, this device regularly transmits radio frequency radiation, the frequency and power of which comply with ARCEP recommendations. Using it in an industrial or hospital environment does not generally pose any problem. However, using it close to certain sensitive electronic systems may lead to interference. Please ensure that installation of this device is limited when in close proximity to any other electronic equipment.
Operation
The secure wandering system is a system that 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. 766 06 configured for this function. This way nurses receive information on the escapee's identity and on the door used.
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 is done manually by entering a special code into the controller keypad. 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*).
• An audible or illuminated warning signal to be triggered
when an escape alarm is activated.
* Product to be ordered separately (see p. 4)

SECURE WANDERING SYSTEM
This system is used to signal crossing of a door threshold by a resident fitted with a wristband Cat. No. 766 20. It works with door unit Cat. No. 766 06 configured for secure wandering and allowing acknowledgement.
Door controller Cat. No. 766 22
1 Wristband activation magnet 2 Detection LED 3 Status LED 4 Coded keypad 5 Enter key 6 Cancel key
Normally situated close to the exit, this controller is the heart of the system. All auxiliary elements are connected to it. A 12-button keypad is used to configure and activate special functions (mode changes, alarm acknowledgement, etc.). A buzzer acts as a warning if an escape is detected. The door controller retrieves the information from antenna Cat. No. 766 21 and from door contact Cat. No. 431 00 and, depending on its usage mode, either triggers a nurse call or locks the door. When the door is locked it can be unlocked using special codes. The coded keypad captures the wristband signal when a predefined door is crossed. Requires a modular 12 V= power supply (Cat. No. 4 131 05).

Antenna Cat No. 766 21
1 Status LED 2 Detection LED
Placed as close to the exit as possible, ideally 50 cm from the ground at the side of the door latch, this element detects the presence of a wristband Cat. No. 766 20 and informs the controller Cat. No. 766 22. The sensitivity and therefore 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. 766 20
Activated or deactivated by passing a magnet over the device. To be performed close to the controller Cat. No. 766 22.
Worn on the wrist or the ankle, this waterproof wristband is fitted with eyelet closures preventing the person under surveillance from taking it off. These wristbands are made of anti-allergy plastic that is capable of being in continuous contact with the skin. The battery has an expected lifetime of more than one year (although replacing the batteries every year is recommended). The weatherproof seal (IP 55) allows residents to take baths and showers. The wristbands can also be cleaned by placing them in an alcohol bath for 5 minutes.
Wristbands 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) exam
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 allows the standalone capacity of the battery to be increased to a maximum 4 years when stored. Once movement is detected the wristband switches immediately to operational mode.
