Simplex 4905-9929 Isolator Module Truealert

IDNAC Addressable Notification SLCs (and legacy TrueAlert SLCs) are internally isolated from each other. In the event of a channel wiring short circuit, the channel will safely shut down and then monitor the wiring for restoration to normal when the short is repaired. However, within the branch and "T" tap wiring of an IDNAC channel, the use of 4905-9929 TrueAlert Isolator+ Modules can provide additional isolation that can reduce the quantity of TrueAlert addressable appliances impacted by a short circuit.
