Compatible Detectors with my 4004

Hello, I recently acquired a Simplex 4004 and was wondering if any new 2 wire smoke detectors are compatible with the panel? All help is appreciated. Thanks.

Do you have any specific detectors in mind? I’ve only played around with 2-wire smokes a bit on my 4004, but every “basic” one that I’ve tried on it (think: System Sensor i3) has worked fine even if it’s not explicitly stated somewhere as being “compatible.” But please take my anecdotal evidence with a grain of salt, always exercise caution when wiring devices to your panel.

Thank you; The I3 is a fine detector that I’m willing to install.

Check your PMs. I sent you a documentation link on Saturday about compatibility.
