Alarm system transformer + power supply (would both go bad atonce?)

I roamed there as GS-12~13 military civie doing C&I and later M&O work for VHF, UHF, Troposcatter radio comm network, Copper lines were only used within the perimeter of bases. Every thing else was tactical/strategical radio. One extra thing I did was looking after VOA relay station in PHu Bai, South of Hue. The station was built on a tiny island in the middle of man made lake accessed only by heavily gated causeway. Nearby also 8th RRFS was station. All under ground except huge antenna farm covering stretch of field. I moved up/down the country frequently from Con Son Island upto DMZ(I was at Dong Ha, Khe san just before USMC was under heavy siege by 'Cong/NVA. After 3 years, I took a R&R, then ordered to show up at Iran or Libya. But I heard those places were worse than 'Nam, so I quit and got married. Wife had a job lined up at Pueblo, CO, my job was at Vancouver, BC(with ITT) When we decided on Canada, I started with Honeywell on computer side(data comm)I was hired by 304th LL Bn under 8th Army in Korea as GS-9. That was half a century ago. Time really flies. Now empty nester. Two kids, one is MD, one is PE, one grand son, 3 yrs old in Victoria, BC. We are in Calgary which is getting too big too fast due to good economic conditions. Between '12-'13 we gained 60,000 in population. |

I immediately reset everything, and I thought it was all ok. Then, today, the alarm system sounded three loud long beeps, and went totally dead. http://farm6.staticflickr.com/5522/1...e48ee609_o.gif Troubleshooting with my Fluke after removing the alarm system external wires shows the external ELK-TRG21640 16.5VAC, 45VA power-supply transformer plugged into an outlet has an open secondary, and when plugged into an extension cord, there is no voltage from any of the three screws on the secondary windings: http://farm6.staticflickr.com/5527/1...d64103f6_o.gif If I thought it was that simple, I'd just replace the transformer; but I wondered why the backup battery didn't run the alarm system. Testing the 12V 5AH battery out of the alarm system shows it's 13.5 volts DC (no load open circuit voltage), which, at least seems OK (I don't know how to load it though): http://farm4.staticflickr.com/3731/1...d9f59f77_o.gif So, two things must be wrong: 1. The ELK AC transformer secondary opened up suddenly 2. Maybe the power supply inside the alarm system box went bad suddenly http://farm4.staticflickr.com/3751/1...ff0ca903_o.gif Do you think shutting the breaker without turning off the generator could have blown the alarm system?

I've always made my own backboards, painted them light grey and drew a 6" grid with a pencil on them so that when the backboard was mounted level, the grid was level I haven't seen anything that neat and organized in a long time. Now the use PC boards and stuff everything in an undersized cabinet to hide the shame... Simplex must have stock in butt splice manufacturers. Then they install the heavy stuff at the top of the cabinet so if it moved it falls on you. I got stories**nightmares of my own... -- Tekkie |

I immediately reset everything, and I thought it was all ok. Then, today, the alarm system sounded three loud long beeps, and went totally dead. http://farm6.staticflickr.com/5522/1...e48ee609_o.gif Troubleshooting with my Fluke after removing the alarm system external wires shows the external ELK-TRG21640 16.5VAC, 45VA power-supply transformer plugged into an outlet has an open secondary, and when plugged into an extension cord, there is no voltage from any of the three screws on the secondary windings: http://farm6.staticflickr.com/5527/1...d64103f6_o.gif If I thought it was that simple, I'd just replace the transformer; but I wondered why the backup battery didn't run the alarm system.

A lot of manufacturers will put power supplies at the top of a cabinet so that cool air is drawn in at the bottom to help cool components. A friend of mine who worked telecommunications in the military for NATO in Europe told me about large Siemens phone switches which were designed with the power supplies at the bottom so the rising heat would keep the electronic circuitry dry. Those switches were designed that way because air conditioning wasn't that common in Europe back then. An AT&T electronic switch of the same era would die if the air conditioning failed to keep the temperature below room temperature. ^_^ TDD |
