Up for sale today is this System Sensor S1224MC fire alarm strobe device. Taken out recently from a working system for an upgrade, but as with any devices,  they should be hooked up and tested before putting into service. All the ones I have do have some paint marks/overspray on them. I don't have the time to clean them all. The pictures show the lot that I have,  so you get an idea of overall condition.  Listing is for 1 single device. They are not pictured, but I will include a mounting plate with each one as well.  I do my very best to describe my items,  but if you have any questions,  or would like a certain picture,  just let me know.    I ship domestically to the 50 US states,  Puerto Rico,  and Guam.   Expert packaging and shipping included for free,  and orders go out very quickly. Thanks for looking
