Hello, I currently have a Costar 12-24SIR in my fire alarm system, and it needs to be replaced. Can you recommend a suitable replacement for this model?
Certainly! For your Costar 12-24SIR, I recommend considering either the CO1224TR or the GD-2B as suitable replacements. Both options are reliable and compatible with various fire alarm systems. If you have any further questions, feel free to ask!
