Abstract
In a security system that has a large number of individually-addressable modules interconnected on a data bus to a control panel, a method of concurrently supervising the modules by first configuring each module with a unique zone number including a group number and a module number. During operation, the control panel initiates a group supervision poll sequence for each group number by transmitting a group poll command including a group number data field populated by the group number currently being polled. If a module is part of the group being polled, then it sets a discrete bit appended to a group poll response message that logically corresponds to the module number for that module. The control panel then determines if any bit in the group poll response message has not been set, and then issues a unit poll sequence addressed to a module that corresponds to any such bit not determined to have been set in the group poll response message.
