Wiring emergency lights?!

[Lucas7]

Hi guys. I need some advice. I'm installing 3 maintained emergency light fittings in a small room. No normal fittings just e/m. I'm using 20mm conduit as containment so will be wiring in 1.5mm singles. I'm putting in a key switch and a normal switch. Can somebody just confirm the wiring for me?! Can I take just 1 feed from the db to 1 of the switches and Link the com's out? Then run a switch wire up from L1 normal to L terminal on each fitting then a switched live from L1 on the key switch to Aux terminal on each fitting. Thanks guys

Nearly....L1 of the switch to Switch L (SWL) of the em fitting.....L1 of keyswitch to L (perm L) of the em fitting...both switch coms linked, and wired to db.
