National Time services Michigan only with a few exceptions. This is because their service department is in Wixom, MI and their support range is limited because they do not have fire alarm distributors. They are primarily in SE Michigan and should be in most of the K-12 schools in this area. Their systems are also present in college campuses such as MSU, Northwood University, Mott CC, and Macomb CC among others. The State Capitol building also has a National Time system in it.
National Time’s clock systems are sold worldwide with installations in Europe, the Middle East, as well as Asia. The company is family owned and operated officially since 1918 with roots dating back to the late 1800’s.
National Time makes their fire alarm systems in the Wixom location (they have another location in Oak Park that fabricates the sheet metal and paints) and by this I mean they actually fabricate the equipment from bare components (PCBs, resistors, diodes, capacitors, etc). They do not make the notification (horns, strobes, speakers)/initiation (smoke detectors, heat detectors, monitoring modules, etc) devices but they do engineer and fabricate the power supplies and control panels. To my knowledge, they are the only fire alarm manufacturer in the US that actually makes their equipment inside the US, not importing it from China and sticking a label “Made in USA” like its competitors do.
The 411/411F are horns are used on their 120VAC 2000 series fire alarm panels produced from ~1950-1990. The 2000 panel is a red panel with large resistors, diodes, relays with analog displays using a needle gauge.
The successor to the 2000 panel - the 7000 panel - is a black panel that varies greatly in size. Modular in design, it is a conventional 24VDC fire alarm panel with initiating and notification cards that fit inside a main board. There many be numerous main boards that house dozens of initiating and notification cards for larger systems. These panels were introduced in the 80’s and were last produced in the 1990’s.
The successor to the 7000 panel was a hybrid conventional/addressable microprocessor based fire alarm system with LCD called the 900 panel. It’s a gray colored panel and can be quite large like the 7000 panel since it has modular pieces as well. This panel started in 1990 and was discontinued around 2020.
The 902 panel has the same gray color as the 900 panel but smaller in physical size. It is the most common and thus flagship panel of the company and is fully addressable for the initiating devices with LCD similar to that found on the 900 panel. This panel was created in 1995 and still manufactured and sold today.
The 910 panel is a fire alarm panel with built in dialer with modernized hardware that can network to both the 902 and 900 panels. At about half the capacity (in terms of devices) from a 902 panel, it’s made for smaller scale installations. The same initiating and notification devices that go on the 902 also go on the 910. It was introduced around 2021 and of course is still being manufactured today.
