UL, ULC, CSFM Listed* Addressable Notification Appliances Addressable Isolator+ Module, Model A4905-9929 modules provide short circuit isolation for TrueAlert notification appliance wiring:** Power and communications are supplied by Autocall 4100ES, 4010ES, 4007ES fire alarm control panels equipped with power supplies provide advanced addressable notification from IDNAC Signaling Circuits (SLCs), and from 4009 IDNAC Repeaters** Operation is also compatible with legacy TrueAlert SLCs from TrueAlert Supplies (TPS) or TrueAlert Addressable Controllers (4009T) Dual port design accepts communications and power from either port automatically isolates one port from the other when a short circuit Mounts in standard 4″ (102 mm) square electrical box, 2 (54 mm) UL listed to Standard 864 diagnostics: On-board yellow LED provides module status, can indicate poll or be activated from panel Isolators report faults to the host control panel (method varies with connection type) received at the control panel allows identification of short circuit location: Autocall control panels providing IDNAC SLCs will be advised of appliances disabled due to activated isolators Other control panels controlling TrueAlert Addressable Controllers do recognize appliance addresses but will receive a report of an open channel trouble due to activated isolators B (Style 4) IDNAC SLC wiring: Up to 12 Isolator+ modules can be connected per IDNAC SLC and up 6 Isolator+ modules can be connected directly together in series on same branch A (Style 6) IDNAC SLC wiring: For Class A operation, up to 6 Isolator+ modules can be connected per loop channel loading rules: Isolator+ modules require one address and are rated as 4 unit loads TrueAlert addressable notification appliances are a single unit load Use of “TrueAlert” in this document refers to both TrueAlert and ES notification appliances. Use of IDNAC SLCs also refers to of TrueAlert SLCs 1: TrueAlert Isolator+ Module One-Line Drawing Including Module Detail Addressable Notification SLCs (and legacy TrueAlert SLCs) are isolated from each other. In the event of a channel wiring short the channel will safely shut down and then monitor the wiring for to normal when the short is repaired. However, within the and “T” tap wiring of an IDNAC channel, the use of A4905-9929 Isolator+ Modules can provide additional isolation that can the quantity of TrueAlert addressable appliances impacted by a circuit. Circuit Isolation. An internal isolation relay allows the Isolator module to separate shorted and/or disabled wiring from functioning to optimize the available appliances. Isolator+ module status is to the control panel providing assistance in identifying shorted wiring location. Location. The A4905-9929 Isolator+ Module mounts in standard 4″ square, 2 deep electrical box, allowing isolators to be located on the IDNAC SLC channel where the local wiring most benefit. This product has been approved by the California State Fire Marshal (CSFM) pursuant to Section 13144.1 of the California Health and Safety Code. See CSFM Listing 7300-2269:0553 for allowable and/or conditions concerning material presented in this document. Additional listings may be applicable; contact your local product supplier for the latest status. Rev. 8 01/2020 Addressable Isolator+ Module, Model A4905-9929 Isolator+ Example 1 Protection. The diagram below illustrates the addition of A4905-9929 Isolator+ Modules to IDNAC SLC wiring located at the start of each With Isolator+ modules added in these locations, there will be an increase in overall system operation in the event of a short circuit. Short Circuits. Without Isolator+ modules, if a short circuit occurred on a branch connection, the entire channel would be inoperative, the as occurs with conventional Notification Appliance Circuit (NAC) operation. With the addition of Isolator+ modules, short circuits would only those appliances connected electrically beyond the Isolator+ module. Since short circuits are sometimes encountered during initial wiring the use of Isolator+ modules can also assist in finding those wiring faults, allowing a decrease in the total installation
