What Signature series devices are compatible with the iO1000 SLC loop, and can I mix legacy and newer devices on the same loop?

The iO1000 is compatible with the entire Signature Series family of intelligent devices, including multi-sensor smoke, heat, and 10-year carbon monoxide (CO) detectors, as well as manual pull stations and various input/output modules (Page 1, 5) [1].

Specific supported modules include the SIGA-REL releasing module, SIGA-CC1S and SIGA-MCC1S NAC modules, and the RZI16-2 remote zone interface (Page 1, 25) [1].

Each loop supports a maximum of 125 detectors and 125 modules (Page 4) [1].

You can mix legacy and newer devices on the same system. The iO1000 is designed for retrofit applications, allowing you to upgrade legacy control panels using existing wiring and supporting new intelligent detection alongside existing conventional circuits via the RZI16-2 module (Page 2) [1].
