3.4.6.3 Modules in the fire terminal
Due to space constraints, no Ethernet switch (MM) FN2008-A1 or Security module
(firewall) FN2009-A1 can be installed in the fire terminal FT724. An additional
empty housing (Eco) 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.
