The overall FDZM, SCZM, and isolator shall each consist of th

18、e appropriate electronics contained inside an appropriate enclosure. The terms “Flame Detector Zone Module”, “Switch Closure Zone Module”, and “isolator”, as used in this specification, refer to the overall FDZM, SCZM, and isolator, consisting of the devices appropriate electronics and the appropria

19、te enclosure. FDZMs, SCZMs, and isolators shall operate properly in both overhead or bulkhead mounted positions. 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-32227 3.3.1 Interchangeability. The AFSSS FDZM shall have a unique model number

20、 assigned to it, and shall be physically identical and interchangeable with all other AFSSS FDZMs from the same manufacturer. The AFSSS SCZM shall have a unique model number assigned to it and shall be physically identical and interchangeable with all other AFSSS SCZMs from the same manufacturer. Th

21、e AFSSS isolator shall have a unique model number assigned to it and shall be physically identical and interchangeable with all other AFSSS isolators from the same manufacturer. 3.3.2 Individual addressability. The FDZM and the SCZM shall each have an adjustable mechanical device or dipswitch that c

22、an be easily set to allow each device to be individually identifiable and addressable by the AFSSS alarm panel once installed in a specific location in a shipboard compartment. Once set, this device or dipswitch shall be easily capable of later being set to a different address, without the use of sp

23、ecial tools or equipment, to support interchangeability. This individual addressability requirement may also apply to the isolator, but it is not specifically required for the isolator. 3.3.3 Enclosure. An enclosure shall securely house and enclose the FDZM, SCZM, and isolator. The enclosure for the

24、 isolator shall possess enough flat surface area to allow two separate LS2SWU-1 cables (see MIL-DTL-24643) (i.e., the sensor loop) with appropriate watertight stuffing tubes (see MIL-E-2036) to penetrate the enclosure. The enclosure for the SCZM shall possess enough flat surface area to allow three

25、separate LS2SWU-1 cables (i.e., two for the sensor loop and one for connection to the switch closure device) with appropriate watertight stuffing tubes to penetrate the enclosure. The enclosure for the FDZM shall possess enough flat surface area to allow five separate cables (i.e., two LS2SWU-1 cabl

26、es for the sensor loop, two LS2SWU-1 cables for the flame detector power loop, and one appropriate shielded, watertight cable for the connection between the FDZM and the flame detector) with appropriate watertight stuffing tubes to penetrate the enclosure. These flat surface areas do not necessarily

27、 have to be all on the same face of the enclosure. All enclosures shall provide a conductive path for the shields of all of their cables to connect to ships hull to provide shield termination. All enclosures shall possess mounting tabs or brackets with clearance holes for bolts that secure the junct

28、ion box to 1-inch long threaded-female metal standoffs welded to the overhead or bulkhead of the compartment. 3.4 Degree of enclosure. All enclosures shall be at least NEMA-4 (National Electrical Manufacturers Association) watertight and dust tight. Thus, standard electrical boxes with holes or knoc

29、kout plugs (which are commonly used for mounting commercial grade FDZMs, SCZMs, and isolators, but are not watertight) are not permitted as enclosures. 3.5 Weight. The total weight of each individual FDZM, SCZM, or isolator (including each of their respective enclosures) shall not exceed 4 pounds. 3

30、.6 Size. FDZMs, SCZMs, and isolators (and their respective enclosures) shall be as compact in size as possible, while allowing sufficient space inside for cable penetrations. The maximum height of each of the FDZM, SCZM, and isolator shall not exceed 9 inches. The maximum width of each of the FDZM,

31、SCZM, and isolator shall not exceed 9 inches. The maximum depth of each of the FDZM, SCZM, and isolator shall not exceed 7 inches. 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-32227 3.7 Interface requirements. 3.7.1 Electrical interface.

32、 3.7.1.1 Sensor loop interface. FDZMs, SCZMs, and isolators shall be compatible with the UL listed AFSSS alarm panel and shall communicate their status to the alarm panel via the LS2SWU-1 sensor loop cable. SCZMs and isolators shall obtain power from as well as communicate their status to the alarm

33、panel over this sensor loop LS2SWU-1 cabling. FDZMs shall communicate their status to the alarm panel over the sensor loop cabling, but shall receive power from a separate flame detector power cable (see 3.7.1.2). The LS2SWU-1 sensor loop cabling shall be routed from the alarm panel to the FDZMs, SC

34、ZMs, and isolators and various sensors throughout the ships compartments and then return to the alarm panel in a looped NFPA 72, Style 6, Class A signaling line circuit (see 6.8.14) arrangement so that single opens on the loop shall not result in the loss of any sensors, flame detectors (via their F

35、DZMs) or switch closure devices (via their SCZMs). 3.7.1.2 Flame detector zone module (flame detector power) interface with the alarm panel. Since power is not supplied to the flame detector via the sensor (communication) loop in 3.7.1.1, a separate LS2SWU-1 cable shall be routed from the alarm pane

36、l to the various FDZMs and then returned to the alarm panel in a looped arrangement to provide power from the alarm panel to the FDZMs. The FDZM shall provide power to its respective flame detector via the cable identified in 3.7.1.3. Thus, in this arrangement, the FDZM shall obtain power from (and

37、be compatible with) the UL listed AFSSS alarm panel and supply that power to its associated/connected flame detector via the cable identified in 3.7.1.3. 3.7.1.3 Flame detector zone module (power and sense line) interface with the flame detector. An appropriate watertight, shielded cable shall conne

38、ct the FDZM to its associated flame detector. This cable shall transfer power (that originated at the alarm panel) from the FDZM (see 3.7.1.2) to the flame detector. This cable shall also transmit the alarm and trouble status of the flame detector to the FDZM to send back to the alarm panel. 3.7.1.4

39、 Switch closure zone module (power and sense line) interface with switch closure device. LS2SWU-1 cable shall connect the SCZM to its associated switch closure device. This cable shall transfer power (transmitted over the sensor loop for SCZMs) from the SCZM (see 3.7.1.1) to the switch closure devic

40、e and shall also transmit the alarm and trouble status of the device to the SCZM to send back to the alarm panel. 3.7.2 Ship interface. The FDZMs, SCZMs, and isolators shall be mounted with bolts to 1-inch long threaded-female metal standoffs welded onto the overheads and bulkheads of the ships comp

41、artments. 3.8 Operating requirements. 3.8.1 Basic operation. When tested in accordance with 4.5.1: a. An appropriate alarm shall register and latch at the alarm panel for the flame detector. FDZMs shall also comply with 3.8.2. b. An appropriate alarm shall register and latch at the alarm panel for t

42、he SCZM. SCZMs shall also comply with 3.8.3. c. An appropriate Class A trouble indication shall register at the alarm panel for the sensor loop. In addition, a second trouble indication stating the loss of the SCZM shall register at the alarm panel. Isolators shall also comply with 3.8.4. d. An appr

43、opriate trouble indication shall register at the alarm panel indicating the loss of the flame detector. FDZMs shall also comply with 3.8.2. e. An appropriate trouble indication shall register at the alarm panel indicating the loss of the flame detector. FDZMs shall also comply with 3.8.2. f. An appr

44、opriate trouble indication shall register at the alarm panel indicating the loss of the SCZM switch. SCZMs shall also comply with 3.8.3. g. The FDZM, SCZM, and isolator shall sustain no physical damage, such as cracks, loosening, warping, thermal deterioration, or dislodgment of parts. 4 Provided by

45、 IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-32227 3.8.2 Flame detector zone module operation. If flame detectors do not interface directly with the AFSSS alarm panel, flame detectors shall interface with the AFSSS alarm panel via a FDZM, compatible

46、with the AFSSS alarm panel, which provides and identifies the unique address of the flame detector and also channels power from the alarm panel to the flame detector. When a flame detector is exposed to a flame of appropriate and sufficient radiant energy, the FDZM shall transmit its associated alar

47、m to the AFSSS alarm panel. FDZMs shall ensure that flame detectors shall be resettable (see 6.8.11) after alarm, but only after a reset (see 6.8.11) at the alarm panel is manually executed and the flame at the detector has been removed (i.e., flame detector alarms shall latch at the alarm panel). F

48、DZMs shall be supervised such that a distinct trouble signal (see 6.8.17) shall register at the alarm panel if flame detector power is not provided to the flame detector. Furthermore, a separate distinct trouble signal shall register at the alarm panel if either conductor on the flame detector sense

49、 line (between the flame detector and the FDZM) is opened. 3.8.3 Switch closure zone module operation. Switch closure type devices shall interface with the AFSSS alarm panel via a SCZM, compatible with the AFSSS alarm panel, which provides and identifies the unique address of the switch closure type device. When any switch closure type device (such as a water flow switch, manual pull station, water switch, and flooding switch) is closed, the SCZM shall tran
