Silent Knight SD505-6IB — 6 in. isolator module for SD505 IntelliKnight addressable detectors on Silent Knight SLC loops.
The SD505-6IB is an isolator module on a 6 in. extension base. It fits underneath the SD505-6AB 6 in. detector base, which holds the detector, so it is not a detector base on its own; the detector is ordered separately. When a short, open or ground fault occurs on the SLC, it reports a trouble and isolates the faulted section while the other SLC devices keep operating.
- Detectors named in the engineering specification: SD505-APS, SD505-AHS, SD505-AIS
- Class A (Style 7) or Class B (Style 4) SLC wiring; fully supervised
- 32 VDC; SLC current 50 µA; 92 µA in standby and alarm on battery
- Maximum loop resistance 50 Ω
- 4-7/8 × 4-7/8 × 7/8 in.; 32–120 °F; indoor use
- UL and CSFM certified; MEA 284-91-E
Not the SD505-6AB detector base it pairs with, and not the SD505-LIM line isolator module. No more than 256 isolator devices (SD505-LIM or SD505-6IB) per SLC loop.
