Addressable Dry Contact Monitor Module: Addressable Monitor Modules shall be provided <br />to connect one supervised zone of non-addressable Alarm Initiating Devices (any Normally <br />Open [N.O.] dry contact device) to one of the Fire Alarm Control Panel Signaling Line <br />Circuit Loops. Monitor modules shall be installed as required by the system configuration. <br />All required monitor modules may not be shown on the Drawings. <br />a. Indication of Operation: An LED shall be provided that shall flash under normal <br />conditions, indicating that the Monitor Module is operational and in regular <br />communication with the control panel. <br />b. Supervision: Unless specifically noted otherwise on the drawings provide one monitor <br />module for each sprinkler switch. <br />2. Two Wire Detector Monitor Module: Addressable Monitor Modules shall be provided to <br />connect one supervised IDC zone, Class A or alarm initiating devices (any N.O. dry <br />contact device) to one of the Fire Alarm Control Panel Signaling Line Circuit Loops. <br />Monitor modules shall be installed as required by the system configuration. All required <br />monitor modules may not be shown on the Drawings. Indication of Operation: Unless <br />otherwise indicated on the Drawings an LED shall be provided that shall flash under <br />normal conditions, indicating that the Monitor Module is operational and in regular <br />communication with the control panel. <br />3. Addressable Control Module: Addressable Control Modules shall be provided to supervise <br />and control the operation of one conventional Notification Appliance Circuit (NAC) of <br />compatible, 24 VDC powered, polarized Audio/Visual (A/V) Notification Appliances. For fan <br />shutdown and other auxiliary control functions, the control module may be set to operate <br />as a dry contract relay. The control module shall provide address-setting means using DIP <br />switches and shall also store an internal identifying code that the control panel shall use to <br />identify the type of device. An LED shall be provided that shall flash under normal <br />conditions, indicating that the control module is operational and is in regular <br />communication with the control panel. <br />a. Configuration: The control module NAC circuit may be wired for Class B with up to 1 <br />Amp of inductive A/V signal, or 2 Amps of resistive A/V signal operation, or as a dry <br />contact (Form C) relay. The control module shall be suitable for pilot duty applications <br />and rated for a minimum of 0.6 amps at 30 VDC. The relay coil shall be magnetically <br />latched to reduce wiring connection requirements, and to insure that 100% of all <br />auxiliary relay or NACs may be energized at the same time on the same pair of wires. <br />b. Power Source: Audio/visual power shall be provided by a separate supervised power <br />loop from the main fire alarm control panel or from a supervised, 3rd party listed <br />remote power supply. AN power sources and connections are not shown on the <br />Drawings <br />c. Test Switch: A magnetic test switch shall be provided to test the module without <br />opening or shorting its NAC wiring. <br />4. Isolator Module: Isolator Modules shall be provided to automatically isolate wire-to-wire <br />short circuits on an SLC loop. The Isolator Module shall limit the number of modules or <br />detectors that may be rendered inoperative by a short circuit fault on the SLC Loop. <br />Modules must be readily accessible (not above ceiling) and clearly labeled. <br />a. Operation: Isolator Modules shall operate such that if a wire-to-wire short occurs, the <br />Isolator module shall automatically open-circuit (disconnect) the SLC loop. When the <br />short circuit condition is corrected, the Isolator Module shall automatically reconnect <br />the isolated section. The Isolator Module shall not require any address-setting, and its <br />operations shall be totally automatic. It shall not be necessary to replace or reset an <br />Isolator Module after its normal operation. <br />b. The Isolator Modules shall provide a single LED that shall flash to indicate that the <br />Isolator is operational and shall illuminate steadily to indicate that a short circuit <br />condition has been detected and isolated. <br />c. Isolation modules must be provided in the following locations as a minimum. <br />1) Immediately adjacent to the Main Fire Alarm Control Unit, at each end of the <br />addressable loop. These two isolators must be within 15 feet of the Main Fire <br />Alarm Control Unit. <br />DocuSign Envelope ID: ECCAC5A0-6CC8-4B37-8AD3-89D69F0AE1AE
