Construction Documents <br />20052.02 / Orange County - Justice <br />Facility <br />28 4600 - 5 FIRE DETECTION AND ALARM <br />C. Notification Appliances: <br />1. Programmable Electronic Sounders (Horns): Sounders located outdoors or in damp or <br />wet locations shall be listed for use in wet locations. Electric sounders shall operate with <br />synchronized audible output and have the following specifications: . <br />a. Voltage: Programmable electronic sounders shall operate on 24 VDC nominal. <br />b. Programming: Electronic Sounders shall provide the ANSI 53.41 three-pulse temporal <br />pattern audible evacuation signal, described in NFPA 72, with an output sound level of <br />at least 90 dBA measured at 10 feet from the device. Output sound level shall be 120 <br />dB maximum. Electronic Sounders shall be field programmable without the use of <br />special tools. <br />2. Strobes: shall be located as shown on the Drawings and provided per the requirements of <br />the NCSBC chapter #11 and ICC A117.1-2009. Strobe lights indicated for use exterior to <br />the building shall be mounted at the indicated elevation and listed for use in wet locations. <br />Strobe lights shall operate with synchronized flash output and have the following <br />specifications: <br />a. Voltage: Strobe lights shall operate on 24 VDC nominal. <br />b. Maximum pulse duration: 2/10ths of one second. <br />c. Strobe intensity and flash rate: Must meet minimum requirements of UL 1971. Provide <br />strobe lights with minimum intensity Candela (Cd) rating of 15/75 Cd, or greater if <br />shown otherwise on drawings. <br />3. Audible/Visual Combination Devices shall comply with all applicable requirements for both <br />Programmable Electronic Sounders and Strobe Lights. <br />D. Miscellaneous System Items <br />1. 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 />DocuSign Envelope ID: 09980A3B-0691-41B4-854D-3865F2287392
