4090-9116 Addressable IDNet Communications Isolators provide IDNet communications isolation to improve installation convenience and increase system integrity. Isolation is automatically activated when an output short circuit is detected and isolation can also be selected manually from the control panel to assist with troubleshooting wiring problems.
Operation. Isolators power up in isolation mode and are directed to connect by the control panel. If the output wiring is acceptable, the isolator will connect to the rest of the circuit. If the output wiring is shorted, the isolator remains isolated.
- Compatible with Simplex® 4007ES, 4008, 4010ES, 4100ES, or 4100U Series fire alarm control panel IDNet Signaling Line Circuits (SLCs) providing: IDNet, IDNet+, IDNet 1+, IDNet 2, or IDNet 2+2 output loops (see additional information on pages 2 and 3)
- Either port can serve as an input or output, ports are automatically separated when a communications short circuit occurs
- Isolation can also be activated from the control panel for system diagnostics
- Mounts in standard 4” (102 mm) square electrical box, the optional adapter plate is available to mount in a 4 11⁄16” (119 mm) square electrical box
- LED flashes to indicate communications; optional covers are available to view LED after installation
- TrueAlarm sensor base IDNet Isolators are also available, refer to datasheet S4098-0025 for details
- UL listed to Standard 864
