Monitor cabinet internal wiring and wiring harnesses shallbe in accordance with the wire list on the

30、 applicable top assembly drawing(TA13220E3900, TA13220E4000, TA13220E4100). Transmission line bracketscontaining lightning and EMI suppression components shall be in accordancewith applicable top assembly drawings.3.5.2 Signal module assembly. The signal module assembly shall contain anaudible signa

31、ling device and the monitor cabinet alternating current (ac)power status indicator lamps.3.5.2.1 Audible signaling device. When actuated, the signaling deviceshall sound at a frequency of 2900 500 Hertz (Hz) and an amplitude not lessthan 60 decibels ( db) referenced to 0.0002 microbars sound pressur

32、e level at adistance of 10 feet on -axis, using “A” frequency weighting. The signal deviceshall sound whenever less than 1 volt direct current ( Vdc) is being applied toterminal board 1, terminal 1 (TB1 -1), referenced to ground, of the signalmodule. It shall also sound whenever the ac power status

33、indicator lamps areflashing (see 3.5.2.2). The audible signaling device shall be silent whenboth of the following conditions exist: a voltage of 4 to 5 Vdc is applied toTB1 -1; the ac power status indicator lamps are continuously on or off (notflashing).3.5.2.2 Monitor cabinet ac power status indica

34、tor lamps. When the monitorcabinet is operating on external 117 (+8, -7) volts ac ( Vac) power, the acpower status indicator lamps shall be continuously lit. When the monitor unitis operating on standby power, the ac power status indicator lamps shall becontinuously off. When the external ac power t

35、o the monitor cabinet isremoved for a period of 3 0.5 seconds or when ac power is re -applied to themonitor cabinet after having been removed, the lamps shall begin to flash at afrequency of 4 0.5 Hz. When the “LAMP TEST/ACKNOWLEDGE” switch ismomentarily set to “ACKNOWLEDGE”, the flashing lamps shal

36、l go to continuouslyoff if the ac power is not present at the time of acknowledge, or tocontinuously lit if the ac power has been restored at the time of acknowledge.Actuation of the switch to “ACKNOWLEDGE” shall at no time prohibit the receiptof any power status change from resulting in the operati

37、on described above.Actuation of the switch to the “LAMP TEST” position shall cause both lamps tobe continuously lit while the switch is actuated.Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL -DTL -52876D53.5.3 Primary power supply. The primary

38、power supply shall operate asspecified herein from 110 to 125 volts, 48 to 62 Hz ac power. The powersupply shall provide a 20 1 Vdc regulated output voltage, a 22.5 3.5 voltsac ( Vac) output voltage, and an unregulated dc voltage as specified herein tomaintain a standby battery supply on trickle cha

39、rge. The power supply shallalso provide, at the battery terminals TB2 -2 to TB2 -1, a fast charge voltagewhich shall function as specified herein. The trickle charge voltage shallvary as a function of the applied loads and ambient temperature in accordancewith table I and the Appendix A test procedu

40、res. The fast charge voltageoutput shall be capable of supplying up to the maximum current specified intable II. The fast charge mode shall be initiated when the voltage at thebattery terminals falls to 24.0 0.3 Vdc (fast charge threshold voltage) forthe 1 and 5 zone and 26.0 0.3 Vdc for the 25 zone

41、 power supply at a roomambient temperature of 77 5 F. For temperatures outside this temperaturerange, the fast charge threshold voltage tolerance shall be 1 Vdc. Thetrickle charge mode shall be restored when the battery terminal voltage rises2 0.5 volts above the fast charge threshold voltage and sh

42、all exist wheneverthe battery terminal voltage is above the fast charge threshold voltage,provided fast charge operation has not been initiated. The power supply shallalso conform to the current output, line regulation, load regulation andripple voltage requirements specified in table II. A power of

43、f/on switchshall be provided which in the “OFF” position shall disconnect ac power andthe standby battery power from the power supply circuitry. With the powerswitch in the “ON” position, a loss of input ac power shall cause the powersupply to automatically operate from the standby battery supply wi

44、thout falsealarm, incorrect status indication or other impairments of function. With abattery (batteries) or equivalent standby supply capable of providing therequired current at 24 Vdc, the power supply shall continue to provide theregulated 20 Vdc output specified. The twenty -five zone power supp

45、ly shallhave a thermal overload switch (thermostat) in the battery fast charge circuitwhich shall open when the switch temperature rises to 150 5 F and close whenthe temperature falls to 130 6 F.3.6 Burn -in. Each monitor cabinet (power supply component only) and powersupply when furnished separatel

46、y shall be subjected to an eight -hour burn -into reduce the number of infant mortality failures (see 4.4.2.4).TABLE I.
