4 wire smoke detector suggestion

[hollisin]

I need to replace two Detection Systems DS200HD 4 wire smoke detectors. Does anyone have any recommendations?
Thanks

System Sensor is one brand to consider.  The i3 series should have a model that meets your needs.  Models are available with or without internal sounders and thermal sensors.

I found this. Does this sound right.
The 4WTA-B is a 4-wire, photoelectric i3 smoke detector with thermal sensor and built-in sounder.

That would be one possibility.  If your old DS200HD also had a sounder, then that's a good match.  If it didn't have a sounder, then you need to check whether your panel's power supply can handle the extra current of 35 mA per unit that the 4WTA-B requires.   You'll probably be ok, unless the panel already is heavily loaded.

It did have a sounder so I will get this one.
Thanks for your help.
