Predict Undocumented Fire Alarm Variants!

Fire Alarm General Discussion
1

As the title suggests, predict rare, unseen variants of fire alarms that you think could exist.

Rules:

  • Your alarm variant(s) must be based on already found variants of a “counterpart” of that alarm (e.g. the WS Strobe on a 7002T) and/or existing variants of the alarm itself.
  • The reason why that variant possibly exists must be cited based on your knowledge of information on it’s counterparts and/or other existing variants of that alarm.
  • No made-up devices or brands! (e.g. Relcot Notify Series) This thread is strictly for predicting rare and unseen devices.
  • Your device can be based off the region that it (or devices of the same brand name) has been seen in.
  • Photos are allowed.

Here are my examples:

Any Simplex 2902 Speaker/Light/Strobe or 2903 Light/Strobe Plate with RED Lens and WHITE Lettering

  • The 2904 series of remote light/strobe, released around the same time as the 2903s, which featured a very resembling design to the lens on a 2902/2903, had two well-known options for the colour of lens: RED or WHITE. (Other colours were also offered)

Any Simplex 2902 Speaker/Light/Strobe or 2903 Light/Strobe Plate with Foreign/Bilingual Lettering

  • Simplex products were offered in Germany and are still offered in Canada (some of which speaks French).
  • Simplex’s famous T-Bars were and still are offered in different languages (e.g. Bilingual English and French, French-only Variants) A German T-Bar has been discovered by @Edwards1250, and a possible photo of a 2903 with German letting has also surfaced thanks to this user.
  • Possible lettering variants include: “FIRE/FEU,” “FEU/FEU,” “FEUER/FEUER.”
  • This also includes ceiling variant lettering and different coloured lenses as well.
  • EDIT: it is confirmed that some foreign lettering 2903s do exist with “FEU” and “INCENDIO” lettering. I would also like to add another possible undocumented variant with Spanish lettering due to Simplex selling some of their products in the Spanish language.
    Here’s an example photo:

Any Wheelock (V)700X(T)/(V(F))3X(T)-VVV*-WS-VVV with RED lens and WHITE lettering

  • The WS-series of Wheelock remote strobes are the same ones used on both 2- and 4-wire variants of the Wheelock (V)700X(T). They were offered with either RED or WHITE coloured lenses.
  • There is proof that these devices were offered from-factory with WHITE body colour, increasing the rarity factors.

I added the photo for the 2902. Everything is photoshopped.

Here is another prediction;

Unpainted White Plastic Simplex 2902/2903 Devices

  • While they were factory-painted, it’s still possible that they were also produced with actual white plastic.
  • More information here.

What if a Beige System Sensor MAEH ADA exited? A Beige MASS ADA Existed (Granted, non likely exist anymore. Unless some haven’t been found yet.) So why wouldn’t a Beige MAEH ADA Exist? Maybe a Beige MAEH Non ADA Existed as well?

Also what if a Ceiling Mounted System Sensor MASS ADA Existed? A Ceiling Mounted MASS Non ADA Existed, so why wouldn’t a Ceiling Mounted MASS ADA Exist?

Because in the mid 1990s, ADA prohibited ceiling-mounted strobes in most cases due to the possibility of smoke rising to the ceiling and obstructing the strobe. I don’t remember the details, but many datasheets in the 1990s included this disclaimer.

Time for another prediction!

Wheelock MIN Horn/Strobes:

  • The Wheelock MIN is the successor to the Wheelock MIZ. Picture shown for reference:

  • These horns, like any other Wheelock product, can come in red and white.

  • Seeing how the discovery of the 712(P(T))-WS-24 chime/strobe happened unexpectedly, it can be assumed that a horn/strobe variant of this exists as well.

  • Predicted Models: MIN-WS-12 and the MIN-WS-24 (other voltages are included as well). As the predicted models suggest, they have a WS Strobe for visual alert on them.
