7044 Ogden Road SE

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. 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. Twentytwo22 will attempt to salvage as much as possible before then.

Former System Specifications

Note: that there is NO panel for this system. It's a hardwired 120VAC system in series, so it's kind of a "1 zone, 1 NAC conventional fire alarm panel".

Notification Appliances

The notification appliances consisted of an Edwards 438D-6N5C vibrating bell, an Edwards "Durabel" 6000D vibrating bell, an Amseco PBA-6-120 vibrating bell, and an Edwards "Adaptabel" 340T square-domed vibrating bell in the 2nd floor storage room. It is known as a "TROUBLE BELL", but has the label ripped off.

Initiating Devices

Pull Stations

The three pull stations consisted of one Edwards 274-111 at the basement door, and two Edwards 270-SPO pull stations in the second floor hallway (one 2nd generation with classic shield and no FIRE ALARM at top, and a rare newer one).

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.
