Fire Alarms in Buildings (2.0)

Main Building - This is one of the most varied systems I’ve ever seen, thanks to countless building modifications. Despite this being a 14-floor building, it doesn’t have voice-evacuation in most areas. What kind of Mickey Mouse operation is this?!
Panel: A two-panel Siemens setup with an MXL (which replaced a System 3 sometime in the 1990’s or 2000’s), and an XLS which was added sometime around 2015 or so. (These setups are officially supported by Siemens. You can tell the system has 2 panels thanks to the 3-part address labels, such as 1-11-21.)
Pulls: MS-151’s in most areas, and possibly some MSI-10B’s.

The monorail platform area has rebranded RSG RMS-1T’s.

Detectors: DI-6’s on the 1st and 2nd floors…

…DI-3’s on the 3rd and 4th floors…

…and OP121’s on the room levels. (The room levels also had DI-3’s or DI-6’s before the refurbishment.)

Near the DI-3’s on the 4th floor there are also some Chemetronics heat detectors which are probably disconnected.

Certain areas like the arcade have FirePrints.

Signals: The few non-refurbished areas (3rd floor and Chef Mickey’s) have Wheelock MT-24-LSM horn/strobes and some current-generation MT’s.

The lobby and arcade have Gentex Commander 3 horn/strobes.

The room levels have Siemens-branded Wheelock Exceder LED horn/strobes, which replaced Gentex GX90S mini-horn/strobes.

The monorail platform has Wheelock ET70WP speaker/strobes.

The 2nd floor (where the ballrooms are) has no signals at all - however, there is a sound system which is probably linked to the panel.

Adding to this, California Grill has ceiling mounted ZNS horn/strobes rebranded by Siemens and a few ZRS strobes too.
