Can I install two different beam detectors from two different manufacturers in the same compartment connected to same panel ?
What brands and what panel are you using?
I don’t see where that would be an issue. Just make sure they are not pointed at each other or that their beams cross paths.
Using Hochiki Firenet Latitude panel with Hochiki beam detector and Fire Ray One Beam detector.
It should be fine, as long as you don’t mess up the wiring. I would check with @Croatian_fire_alarms. He is in that buissness with the devices.
its ok if the fire ray has an addressable module on it
