7044 Ogden Road SE is a small apartment building in Ogden. It was built in 1914 as a Chinese laundromat with a boarding house upstairs. It's system is quite interesting, as it has no actual panel and simply operates off of 120VAC, with the bells in series with the initiating devices. The system's parts dated from 1958 to the 2000s. Obviously the components are not original. Unfortunately the 106 year old building is slated for demolition in February 2021 to make way for the new Green Line LRT. As of February 19th, 2021 User:Twentytwo22 has salvaged all but two devices.

Former System Specifications (1958-2021)

The building was protected by a hardwired fire alarm system, so there was no panel.

Notification Appliances

The notification appliances were:

  • An Edwards 438D-6N5C vibrating bell, (6" gong)
  • An Amseco PBA-6-120 vibrating bell (6" gong) as a deficiency replacement
  • An Edwards "Adaptabel/TROUBLE BELL" 340-T square-domed vibrating bell in the 2nd floor storage room, the label was missing.


The Edwards 438D-6N5C and Amseco PBA-6-120 bells were saved from demolition by User:Twentytwo22. He now owns the 438D-6N5C, while the PBA-6-120 bell is safe in TwentyThree33's Collection.

Initiating Devices

Pull Stations

The three pull stations consisted of:

  • An Edwards 274-111 conventional pull station at the basement door
  • Two Edwards 270-SPO pull stations in the second floor hallway; one was a second-generation (no FIRE ALARM, classic shield), and the other was a rare, newer variant, this one was a deficiency replacement.

Automatic Detection Devices

There automatic detection devices consisted of two American Sensors ESA5011 ionization 120V smoke detectors with an auxilary contact on the second floor, and in the basement laundry room respectively. [further investigation will provide an update soon]. When a pull station is pulled, the smoke detectors also sound. [[]
