Fire Alarm Activation #6

Описание: This is a compilation of fire drills conducted at the high school I attended. This high school was built back in the early 1960s. There's very little remnants of the original fire alarm system, but the recessed cages may have had bells in them. At some point in the 1980s, an Edwards fire alarm system was installed, hence the Edwards 892 series signals and 270-SPO pull stations. Unsure of what panel this was, but it was likely some larger conventional panel (i.e. ESA-2000). I have never seen the current panel, but based on the devices, it's probably an NFS-640 or NFS-3030 (my elementary school has an NFS-640).

The high school has a wide variety of devices, with older Edwards signals mixed in with System Sensor and Wheelock signals. There's no strobe synchronization, and initiating devices are a mix of conventional and addressable. It's a messy system, although there were never any obvious issues when I attended the high school.

For the intro of this video, the fire drill was announced ahead of time. In all other instances, the drills were unannounced (although they happened predictably around the early afternoons).

Components:
Notifier Fire Alarm Control Panel (NFS-640 or NFS-3030?)
Notifier FSP-851 Smoke Detectors (not seen in this video)
Notifier NBG-12LX Pull Stations (not seen in this video)
Edwards 270-SPO Pull Stations
Edwards 892 Series Horn/Strobes
STI Stopper II Pull Station Covers
System Sensor SpectrAlert Classic Horn/Strobes
System Sensor SpectrAlert Advance Horn/Strobes
Wheelock Exceder Series Horn/Strobes (not seen in this video)
Wheelock MT Series Horn/Strobes
Wheelock NS Series Horn/Strobes
Wheelock RSS Series Strobes (not seen in this video)

There's likely many other components in this very mixed system.
