Fire Alarms in Buildings (2.0)

Some recent photos I’ve taken:

At an Ace Hardware near me:

Siemens ZH-MC-CR horn/strobe:

Siemens HMS-S or MS-51 (newer generation) pull station blocked by a box of pool noodles:

For some reason, many emergency lights in the store were on dimly, although they showed that they had AC power:

At my local Walmart:

Wheelock S8-24MCC-FW speaker/strobe:

This Walmart is located directly next door to my school, so some people go there for lunch. I was sitting at a table in the Subway today, when I decided to snap this quick photo. I’ve always loved how these devices look, especially on a drop ceiling or drywall ceiling. This Walmart location is pretty interesting with the fact that they are still actively using the SAFEPATH system. They have the new paging/music system with the new tones and Walmart Radio announcements, but they opted to not upgrade the speaker system. Instead, they are still using the SAFEPATH system as the speakers throughout the store, and the show no signs of changing that. The speakers in the Subway are fed from a Wheelock SP-SVC volume control knob, which controls the music and general paging volume, but is overridden when an alarm or all call is going though the SAFEPATH system. The old owner of the Subway always kept this knob turned all the way down, so the speakers in the restaurant never made any sound. The new owner turned it all the way up, so the speakers in the restaurant are at the same volume as in the rest of the store. This is a full voice system with mostly Wheelock S8-24MCC-FR speaker/strobes, but the restrooms have E90-24MCC-FR speaker/strobes, and the coolers have ET70WP-2475W-FR. The 75 candela is not necessary, but it’s the lowest strobe intensity that the ET70WP devices were sold in.
