Notifier AM2020-AFP1010 Supplement-Factory Mutual

AM2020 MUTUAL Number 50123 E ECN 00 407 One Releasing Service 1.1 Introduction supplement describes the requirements of using the AM2020 AFP1010 in Factory Mutual releasing or pre applications For complete information on installing programming and operating the AM2020 refer to Document 15088 When used for CO2 releasing applications observe proper precautions as stated in NFPA 12 not enter the protected space unless physical lockout and other safety procedures are fully completed not use software disable functions in the panel as lockout 1.2 Standards AM2020 AFP1010 may be used as a control panel for agent release or pre action deluge applications When with compatible approved actuating and initiating devices the system meets the requirements of the standards NFPA 12 NFPA 12A NFPA 12B NFPA 13 NFPA 15 NFPA 16 NFPA 17 NFPA 17A NFPA 2001 Extinguishing Systems High Pressure Only 1301 Extinguishing Systems 1211 Extinguishing Systems Systems Spray Systems Deluge and Foam Water Spray Systems Chemical Extinguishing Systems Chemical Extinguishing Systems Agent Fire Extinguishing Systems 1.3 Releasing Functions Switch Once an initiating device has been activated the abort switch may be used to manually prevent at least delay the release from taking place while the source of the alarm is being investigated There are types of abort operation which are explained in Section 1.4 Zone Certain releasing systems require more than one initiating device to enter alarm before a release take place this is generally referred to as a cross zone or counting zone Time Delay time is defined as the amount of time between activation of an initiating device s and the at which the release takes place Note In the case of a cross zone system activation of more than one device is required Time The soak timer is used to automatically turn off the releasing solenoid after a predetermined amount time typically 10 or 15 minutes Note This feature should only be used in NFPA 16 applications 1.4 Abort Modes AM2020 AFP1010 may be used in one of two releasing modes ULI type or IRI These two modes of operation described in detail below Compliance with these modes of operation have not been investigated by Laboratories UL but have been tested and approved by Factory Mutual FM Abort Standard UL type delay timer which continues to count down even after the abort switch has pressed but stops and holds at 10 seconds for as long as the switch is held Upon release of the abort the timer resumes counting down from the 10 second mark Abort Functions the same as the ULI type with the exception that the abort switch will only function if it is and held before the second initiating device cross zone goes into alarm Factory Mutual Applications 50123 E 7 26 00 Two Hardware Requirements 2.1 Initiating Devices initiating devices used to activate the releasing outputs may be FSP or FSI intelligent smoke detectors FDX heat detectors or conventional detection devices that are listed for this purpose and connected to FMM modules Several of these initiating devices may be used for the same releasing hazard by mapping them the same releasing zone Factory Mutual and certain Local Authorities Having Jurisdiction require that wiring NFPA Style 6 for SLC loop and NFPA Style D for initiating loop be used for the initiating devices releasing applications 2.2 Warning Sounders sounders may be connected to any Notification Appliance Circuit originating from a Control Module refer Document 15088 and 51253 for specific Control Module installation instructions Multiple Notification Appliance may be activated by a single releasing hazard These warning sounders may be programmed to activate different conditions such as When the delay timer is activated When the releasing device is activated Upon first initiating device initiating zone activation Upon cross zone second initiating device activation Refer to Section Three for specific programming information 2.3 Releasing Device Circuit Resistance using the AM2020 AFP1010 for releasing or pre action deluge applications the wiring for the releasing must be configured to maintain a minimum of 20.4 VDC at the releasing device The formula shown below be used to calculate the maximum allowable resistance due to wiring on the releasing circuit 20.6V 20.4V Is Rmax equals the maximum allowable wiring resistance and Is equals the solenoid current A remotely mounted MPS series power supply with an MPS TR module for supervision may be used to minimize voltage drop on the releasing circuits 2.4 Factory Mutual Releasing Requirements Factory Mutual requires 90 hours of standby in all pre action deluge applications Factory Mutual also requires redundant wiring NFPA Style 6 for SLC loop and NFPA Style D for initiating on all initiating device circuits used in pre action deluge applications For NFPA 13 and NFPA 15 applications the soak timer must be disabled For NFPA 16 applications the soak timer must be set to 10 or 15 minutes Do not program an abort switch for deluge pre action applications 2.5 FM Approved Releasing Devices following is a list of Factory Mutual approved releasing

be programmed to meet the specific requirements of FM releasing service The modes of releasing service and the software programming required to perform these modes are shown 3.2 Single Zone Releasing equations shown below detail how the AM2020 AFP1010 may be used to control a simple single zone system Upon activation of any single initiating device a delay timer will start counting down When the timer reaches zero the releasing solenoid will be energized There is no abort switch and no cross zoning the system Zone Zone Type CBE Description initiating devices for releasing service Za timer starts when Za enters alarm The delay timer xx may be set from 00 to 59 seconds The releasing Control Module should be mapped to Zone b Zb To activate the warning sounders upon first alarm start of delay they should be mapped to Za To activate the warning sounders upon release they should be mapped to Zb The SDEL equation for Zone b insures that the releasing solenoid will remain energized even if the initiating mapped to Zone a returns to normal For NFPA 16 applications only change the Control By Event equation for Zone b Zb to the following
