don't have any manuals, sorry, we just do a lot of them
maintenance mode drops the threshold of the detectors, meaning they are very quick to set off, however it doesn't just put them into pre alarm, it does put them into full alarm, it just changes the level that this will happen at.
while this may appear to not be a full test, you're still checking that the chamber will react to smoke, and set the panel into alarm (you can check the maintenance historic log to check that the devices you're testing do register at the panel if you're really dubious about any of them) zetfas panels work a lot like this during testing as well. you CAN set them off with solo smoke or similar without them being in maintenance mode, you just have to be very careful to not spray them too much.
thankfully we're phasing the zetfas and securiton systems out of our portfolio, they're ok so long as the engineer working on them has enough experience but they're both, though especially the securiton, just far too complex for what they're being used for. plus the fact that to do any type of major fault finding on either of the systems you HAVE to have the software.
and yeah, the german's great. you program all your menus but most of the worst faults still appear in german (securiton are actually swiss iirc)
