7.4 Loop Device Class Programming
Loop devices may be programmed to belong to a certain class. The currently available class options
are:
Automatic Class
Standard detection devices (for example, optical smoke detectors or heat detectors).
Manual Class
Manual Call Points are programmed as manual class. When activated, devices programmed as
manual class will override any programmed system delays.
Silence, Reset, IReset, Sound Alarms and Accept Class
Loop devices programmed into any of these classes will mimic the relevant 6100 button press when
activated. The loop device itself must be set to non-latching, but not programmed as non-latching on
the 6100.
Invisible Switch Class
Loop input devices may be programmed to be ‘Invisible Switch’ class. The loop device itself must be
set to non-latching, but not programmed as non-latching on the 6100.
Invisible switch class devices can trigger input groups and activate output groups via the cause and
effect matrix but, unlike Automatic and Manual class devices, do not activate any panel indications,
internal buzzer, fire link outputs or global fire contacts.
Disable Control Output Groups Class
Loop input devices may be programmed to be ‘Disable Control Groups’ class. The loop device itself
must be set to non-latching, but not programmed as non-latching on the 6100.
Disable Control Output Groups class devices, when active, disable output activations to loop devices
assigned to control type output groups. Devices in alarm type output groups still operate.
Disable Output Group 31 and 32 Class
Loop input devices may be programmed to be ‘Disable Output Group 31’ (or 32) class. The loop
device itself must be set to non-latching, but not programmed as non-latching on the 6100.
Devices programmed to class ‘Disable Output Group 31’ (or 32) disable activations to output group
31 (or 32) when activated. This may be found to be an advantageous feature in certain installations
where output devices must be temporarily disabled under certain conditions.
