My Fire Alarm Pics

From my dad’s job:

One of two Simplex 4100U panels

An FOS 6120 on a Simplex 2903-9101 strobe plate. Most parts of the old wing have these. Strangely, all of them have the strobe on the bottom.

In some parts of the old wing, the 6120’s are on SAE A34 strobe plates.

There are also a few SAE V33 remote strobes on the ceilings.

Recently, one of the 6120+A34 combos was replaced by a Simplex rectangular horn/strobe (yes, they are still in production.)

Most of the pull stations are made by Autocall.

Although a decent number of pull stations are Simplex 4251-20’s.

There are two Simplex Chevrons.

There is one Wheelock MT that is used to signal fire suppression release.

This is the 4100U in the new wing.

Most of the signals in the new wing are Simplex TrueAlert speaker/strobes.

There are TrueAlert remote strobes in smaller areas that don’t need speakers.

The pull stations in the new wing are dual-action Simplex t-bars. They are probably addressable, considering the panel is a 4100U

There’s another agent release signal in the new wing. It’s a Wheelock RSS

The photos didn’t show up due to how they were tagged, but I was able to see them by copying and pasting the URLs into my browser.
Pretty neat stuff, though!
As for the rectangular Simplex horn/strobes still in production, that is true. However they use the same horn sounder as the TrueAlert horn/strobes do!

HTML tags don’t parse on phpBB. Instead, take the “img src” address and paste it inside of the BBCode image tags.

Thanks. Sorry about not deleting it earlier and fixing it myself.

At a Best Buy

Simplex dual-action 2099/4099

Two TrueAlerts side by side. Most of them have one horn/strobe and one remote strobe, but this one was two horn/strobes.

A horn/strobe and two 2098 test stations.

Close-up of a TrueAlert.

There was also a 4010 annunciator in the front entrance.

At a hospital parking garage:

A single-action 2099

A 2901-9838 on a 2903 strobe plate.

That was only a fraction of the alarms in the hospital. Most of the alarms in the parking garage were 2901-9833’s on 2903 plates, and the pulls were 4251-20’s or 2099-97**'s (the early 2099’s that look like 4251’s). The indoor part of the parking garage has the single-action 2099’s and 4903 speaker/strobes. The main hospital has dual-action 2099’s for pulls and a mix of 2902-9711’s on 4905+4904 strobe plates, 4903 speaker/strobes, and one 2902-9711 on a 4903-9105 plate. The detectors were a mix of TrueAlarm smoke detectors (old and new), one TrueAlarm heat, and one thick-based simplex smoke that looks like this:

At a shopping plaza:

A flush-mounted Gamewell fire alarm box.

Another coded box. This one was made by a company called Narrington Signal.
