In your area, what type of alarms do you see the most?

Here in Washington D.C., the most common alarms I see are U-NH-MCS’s, RSS’s, CH-70’s, and Wheelock Exceeders. The most popular pull stations I see are BG-12’s and that Siemens one I have still yet to find the model number.

If this is the alarm, it is a Siemens MS-501.

That’s actually a MS-51. This is an MS-501:

Sorry! :oops: So the MS-51 is single action and the MS-501 is the dual action?

That is correct.

Here’s a graph I made. These are systems that I can remember, and ones that I know of.
