your sunday punch and it's a pretty good bunch your equipment is modern and mobile your firemen are trained and courageous every time they go out they know they may give their lives trying to save your life or your property unfortunately it's an uneven battle they go into in a war that never and now we're going to meet one of the general staff commanding our forces chief walker if we only knew where fire was going to break next we'd be there waiting for it usually we're only minutes away but those are the minutes of count most because the extent of loss depends upon what happens in the first five minutes fire start in many ways defective wiring spontaneous ignition careless smoking but one thing most of them have in common they small big fires are only small fires that have had time to grow and it doesn't take long buildings even fire resistant buildings often miss called fire from plenty of flammable material until you've experienced it you just can't realize how fast  blaze can cripple its size in sixty seconds in another minute or two it can increase tenfold and ten minutes after it starts a fire can easily be one hundred times the original size when this happens you just have to watch him burn and try to protect other buildings nearby that's the reason that the first five minutes are worth more than the next five hours one trouble is many commercial and industrial buildings are closed up to seventy percent of the time counting nights weekends and holidays so the blaze isn't discovered till it has gotten a head start even with a watchman or guard on duty you can't be everywhere at once and even when people are around there is no guarantee they'll do the right thing there's something about a fire that panics people sometimes they try to fight it themselves and don't call us until  blaze gets out of hand or they waste time looking for a fire alarm box or on the telephone they get excited give us incomplete information and hang up those are some of the reasons why fire losses in this country run more than a billion dollars a year and wildfire kills around eleven thousand of our fellow citizens every year but now we come to the brighter side of the picture that is our losses are there would be many times worse were it not for modern science a combination of ingenious devices stands guard over all types of property today you all know what this is an automatic sprinkler using them on pipes running along ceilings but not many people know about the rest of the system unquestionably the automatic sprinkler system is a tremendously valuable defense against fire one is working properly a sprinkler system acts fast and effectively in those vital first five minutes bus the human element can rob the sprinkler of its powerful punch the sprinkler can be crippled or it can be put out of commission altogether if a shutoff valve is carelessly are maliciously if the water level is too low and gravity or pressure tanks or the air pressure in pressure tanks is too low if the water in a gravity tank is frozen in a cold way if the steam pressure to engine driven pumps the subnormal or if the electric power to firebombs this fa even though the sprinkler system is capable of full operation someone has to hear the gong and call the fire department because the water must be shut off after the fire is out but not until the fire but modern science has perfected a way to make sure that all supply units of a sprinkler system are always ready to operate and the trained alert men won't instantly take action the minute water starts flowing this is central station when this service is at the moment the first sprinkler goes off a red light flashing warning sound the operator reads the signal on the tape from the code the assignment book instantly shows the exact address even the area of the property from which the alarm has come disadvantage alone say it's precious moments a code transmitter notifies the fire department of the fire and its location with this information we know at once what type of equipment will be needed at that property and in a matter of seconds it's on its way t guard is also on route to subscribers notified at the premises if it's night weekend or holiday a d t notifies him at home in a case like this we have a first great chance of getting to the fire in time and we have a chance to keep the losses low both in life and property but chief walkers opposed the sprinkler system doesn't work for some reason suppose it's turned off or there's some other malfunction or one of the complete protection system the minute the water supply in the pipes is cut off or reduced that is reported instantly and a d t investigates immediately and follow through with it until normal conditions are restored b as a matter of fact i remember an instance where an arsonist was trying to set fire to a building the sprinkler system would give the alarm so he shut off the water not knowing that that turned in an automatic warning just the same he was just starting his fire when they caught it and him too but it's a good one but aren't there places where his sprinkler systems are not installed for some reason oh yes of course such places need a way to detect fire and transmit an alarm even more for them there are various automatic fire alarm systems one of these is the arrow system it is a simple circuit a very small diameter copper tubing which runs along the ceiling the tubing contains air that expands on any rapid rise in temperature that sends an instant alarm into the a d t central station there are still other types of course engineers according to the kind of building and this particular hazard such as the telesur i'm system which converts the radiant heat of the fire into electrical energy and actuates the alarm are for places where fluctuations are common they have a special thermostat that actually can tell the difference between a friendly fire completely protected property today often a small wastebasket fire automatically has a fire department on the scene more than once we've arrived in answer to an a d t call before the people who are working there knew their place was burning must be a shock to find the fire department putting out a fire they didn't know they had yes but it's a wonderful feeling of security for the property owner and we're for anything that helps us do our job better like such a simple thing is private fire alarm boxes private alarm boxes or yes they are manually operated the same as the public boxes but they are strategically located right on the property they give the exact address of the fire not just the general neighborhood live gives me an idea yes mr mallock why couldn't the firm buy these different gadgets direct make up their own electric protective system train their own minimum to operate it well even if all the equipment was made by the same manufacturer they would be undertaking considerable expense for a retail operation that a d t does on a wholesale basis providing both economy and efficiency and the first time they really needed it they might find that their protection system  falling down and some vital far through inexperience neglect or a change in personnel take one item alone first maintenance without it the system becomes worse than useless because you will be relying on something that may fail right when you need it simply from overside are neglect your maintenance staff may have a hundred other gadgets to maintain a d t has no more important than maintaining the protection service on your premises that's more important to you than devices wire conduit even in remote locations a d t provide service to several thousand communities throughout the united states and through affiliates  canada sixty three thousand subscribers and property protected in excess of fifty three billion dollars can't be wrong i'll go along with that yes modern science in this case through t has given us real protection that saves property and frequently lives by giving the fire department a chance to get there in that vital first five minutes thank you chief walker of course there are establishments that still don't have automatic protection but in the thousands of communities from coast to coast where it is available subscribers appreciate the feeling of security it gives them immunity not only from very often automatic protection service cuts the cost of insurance and usually guards and watchman can be replaced by a combination of fire and burglary protection systems so that they can be transferred to productive job and where it is necessary sciences even develop supervisory services that watch over industrial processes this must continue unintended at night or during other close various when something goes wrong and a warning signal automatically goes to the central station so that corrective actions can quickly of course there is another serious hazard that every business man faces constantly and that is for millions of dollars of loss nationally that is for places that are not sufficiently productive for our story on that we call on police chief anderson chief anderson there are several ways that our problems parallel those a fire chief walker we don't know where the criminals are going to strike next until they've struck and we too can do our job a lot better an serve the public better if we can get there within the first few minutes and science is helping you to tremendously a moment ago you witnessed an illegal entry if that had been automatically protected property the chances are we would have had that fellow by this time and naturally they amount and type of burglar alarm service differs with the premises and conditions but let me show you some other ways that discourage any burglar a chain link fence topped with barbed wire and have to keep out of control intruders but this man has brought wire cutters what he doesn't know is hardly get through the fence before an electronic detector starts so warning light in the a d t central station and sends out a signal of a problem with the exact address operator's receive and verify the s transmit the alarm to the police fantastic and say the intruder hired a helicopter to drop him inside the electronic fence let's pretend he somehow is reached the building outside a window if you break that window the flashes the six if you jimmy's it open without breaking it he still flashes a signal but he doesn't realize even as he stands there wondering what to do to avoid detection he is flashing a signal right now a d t already knows the police are already on the way and again the prowler betrays him self before he can even enter the building but let's say he doesn't go near a window what about the back door the results are the same no matter how he gets through that door automatically unwittingly he gives himself away what about the skyline what about digging is wade through the wall maybe from some building next door that is not protected by a d t yes you guessed it the first thing you know whom we've got it usually before has had time to disturb anything inside i don't mean that every establishment has all of these devices or needs a t t that's the american district telegraph company they've been in this business for more than eighty years they send out a protection specialist to survey each plant and see just what is needed in the way of fire and burglary protection they work closely with the police with the fire department and the underwriters in fact you probably know that most types of this service automatically cut the cost of burglary insurance considerably why oh yes but the devices i've talked about so far they're all designed to detect attacks from the outside the protective devices inside a building or even more amazing if possible again for the sake of again or maybe this is the type of concern having a large say for of all that holds money jewelry for narcotics anything easy to make off with great value unfortunately there isn't a safer of all made that a determined burglar can't open given the time in the proper tools we can't prevent him from obtaining the tools but we can keep him from having the time as with exterior protection there are several ways of doing this d t can throw an electromagnetic field around a safe the transmitter is a sign of alarm the moment anyone even approaches and it's called tell approach or they can surround the safe with an electrically lined cabinet the minute anyone tries to open or cuts for any part of it that transmits an alarm to the a d t central station or they can install a phone that alarm system sensitive microphones in the ceiling of a fault they instantly detect the noise of anyone trying to enter through the walls ceiling floor or door man automatically flashed the a lock well all i have got to say is i don't see how a burglar going to make a decent living anymore he can not from a place that is automatically protected in fact most burglars shy away the minute they see the sign because the professionals at least know that they just can't beat the science of electric protection no wonder you welcome help like that yes if everyone had this automatic protection oh needs it most crooks would have to go into some of the business and there'd be far less sabotage and vandalism to all but of course the burglar alarms are turned off during the day while people are at work yes and turned on when they leave but there are other devices that are never turned off as in a bank here is a demonstration booth that could be a teller station we're not going to show any of the hold up devices here for obvious reasons and still transmitted a sign of the law without giving the slightest hint to call for help this is how modern science is helping the forces of law and order serve the public better hundreds of billions of dollars annually because whether it's
