Description
4905-9929 Simplex, Isolator Module Trualert.
The 4905-9929 Simplex TrueAlert Isolator Module is intended for use on TrueAlert Addressable circuits to isolate short-circuited wiring from functioning wiring.
4905-9929 Simplex, Isolator+ modules provide short circuit isolation for TrueAlert addressable notification appliance wiring:
- Power and communications are supplied by Simplex 4100ES, 4010ES, and 4007ES fire alarm control panels equipped with power supplies that provide advanced addressable notification from IDNAC Signaling Line Circuits (SLCs), and from 4009 IDNAC Repeaters.
- Operation is also compatible with legacy TrueAlert SLCs from TrueAlert Power Supplies (TPS) or TrueAlert Addressable Controllers (4009T).
- The dual-port design accepts communications and power from either port and automatically isolates one port from the other when a short circuit occurs.
- Mounts in standard 4″ (102 mm) square electrical box, 2 ⅛” (54 mm) deep.
- UL listed to Standard 864.
Information received at the control panel allows identification of the short circuit location:
- Simplex control panels providing IDNAC SLCs will be advised of individual appliances disabled due to activated isolators; (also true of legacy panels with TPS or when connected to TrueAlert Addressable Controller using RUI communications).
- Other control panels controlling TrueAlert Addressable Controllers do not recognize appliance addresses but will receive a report of an open circuit channel trouble due to activated isolators.
Class B (Style 4) IDNAC SLC wiring:
- Up to 12 Isolator+ modules can be connected per IDNAC SLC and up to 6 Isolator+ modules can be connected directly together in series on the same branch.
Class A (Style 6) IDNAC SLC wiring:
- For Class A operation, up to 6 Isolator+ modules can be connected per SLC loop.
General channel loading rules:
- Isolator+ modules require one address and are rated as 4 unit loads.
- TrueAlert addressable notification appliances are a single unit load.
