I have several of these horns because I’ve had several of them unexpectedly break on me.

#### Simplex 2901-9833

**Category :**Simplex

One more duplicate of the Simplex 2901-9833. I don’t know if these horns really do break this easily or if...

#### Simplex 2901-9838

**Category :**Simplex

This horn is designed to go with a Simplex 4903-9101. The grilles on these horns scratch very easily. Luckily, I...

I had to take a guess as to what this ceiling-mount light’s model number is, so 2904-9201 may not be...

#### Simplex 2904-9103

**Category :**Simplex

This unit is a light, not a strobe. I’m pretty sure that 2904-9103 is the correct model number.

**Category :**Simplex

This was the my second control panel and is currently the one that I have up for the wall system....

#### Simplex 4005-9101

**Category :**Simplex

This horn runs on AC power and goes with my the Simplex 4050-001 light plate.

**Category :**Simplex

You can see what the horn and the light plate look like together in the last picture.

**Category :**Simplex

I currently do not have base for this smoke detector. It is similar to the Simplex 4098-9714.

#### Simplex 4098-9716

**Category :**Simplex

I don’t think that I have a base that is compatible with this head.

**Category :**Simplex

This is a photoelectric smoke detector from the mid to late 1970’s.

**Category :**Simplex

What code this pull station does currently escapes me. It is similar to my Faraday 10508A.

#### Simplex 477-669

**Category :**Simplex

Oddly enough, the model number on this particular smoke doesn’t fit the typical pattern for Simplex devices.

#### Simplex 4901-9811

**Category :**Simplex

This particular alarm is actually capable of doing three different tones.

**Category :**Simplex

Unlike the Simplex 4903-9101, this is a light plate rather than a strobe.

#### Simplex 4903-9105

**Category :**Simplex

I think that this strobe plate actually uses the same housing that the Simplex 4903-9101 uses. The strobe is obviously...

**Category :**Simplex

This is a SmartSync TrueAlert which I am able to use with my Simplex 4010.

#### Simplex 4903-9418

**Category :**Simplex

The lack of TrueAlert branding on the front of the alarm, as well as the odd grille, are signs that...

#### Simplex 4903-9425

**Category :**Simplex

This alarm is a TrueAlert. Unfortunately, its horn was DOA, but the strobe still functions fine. I have a spare...

#### Simplex 4903-9427

**Category :**Simplex

This unit is almost identical to my Simplex 4903-9425, except the strobe candelas rating is different, and this unit functions...

This is, in fact, a Simplex 4904-9137. It’s just missing its housing.

#### Simplex 4904-9137

**Category :**Simplex

In order to un-mount this series of strobes, the strobe has to be snapped out of the housing since the...

#### Simplex 4904-9139

**Category :**Simplex

I believe that this strobe plate was designed to be used with bells, such as the Simplex 2901-9333.

**Category :**Simplex

This strobe is essentially a white Simplex 4904-9137, but with a different candelas rating.

#### Simplex 4904-9169

**Category :**Simplex

This strobe is an early TrueAlert model, which can be assumed because it is missing the “TrueAlert” lettering found in...

**Category :**Simplex

This is the Simplex 4010 user interface which was taken out of a broken 4010.
