system installation (continued)
Chaperone
The controller must be set to chaperone mode for a
set time period (chaperone period) in order to allow a
wristband wearer to go through an exit without setting
off the alarm.
This is done by entering a code on the keypad or by
activating the chaperone input (via a pushbutton or
keyswitch, etc.).
The chaperone contact must be normally open or normally
non-powered.
For optimum security the controller returns to surveillance
mode once the door is opened and closed. The chaperone
period is cancelled.
acknowledgement
When an alarm is detected the alarm output and the
buzzer remain active until they are acknowledged.
Acknowledgement is via the door unit Cat No. 766 06
by pressing the nurse presence button.
Mode selection
The changeover from surveillance mode to intruder
mode and back can be controlled by the state of this
input. When the contact is open (or the input is not
supplied with power) the system is in surveillance
mode. When the contact is closed (or the input is
supplied with power) the system is in intruder mode.
The system state can therefore be controlled by an
external device (clock etc.).
When this input is not being used, the changeover from
one mode to the other is achieved by entering a code on
the keypad.
