3.4.6.2 Modules in station with Standard housing
Due to space constraints, no Ethernet switch (MM) FN2008-A1 or Security module
(firewall) FN2009-A1 can be installed in a fire control panel FC722. An additional
empty housing (Eco or Standard) is needed for this application and is fitted under
the fire terminal.
NOTICE
Protection from battery leakage
The cable connections into the bottom housing must be led through a packed
gland to ensure protection from battery leakage.
