4.3 The SmartLoop/2L board
All the SmartLoop 2080 series (expandable models) have 2 on-board loops expandable to 8 by means
of 3 SmartLoop/2L expansion boards. The models SmartLoop 1010 series (non-expandable) have 1
loop only.
Each loop accommodates up to 240 or 126 (depending on the selected protocol) fire detection/
signaling devices (refer to Appendix B).
Due to electrical incompatibility (refer to Appendix B), different brand devices (i.e. devices using
different protocols) cannot co-exist on the same loop. However, the loops can be programmed
separately thus allowing the system to manage different brand devices on different loops.
