How Do I Choose A Residential Locksmith in Fitzroy North?Electromagnetic LocksElectromagnetic locks are widely used in commercial and industrial applications. The lock is usually mounted on the header above the door and the armature is usually mounted on the door (see drawing below). Different arrangements can be made for inswing or outswing doors, and different holding forces, monitoring switches, and other variations and options are available. In this article I will discuss only the basics. As with any locking system, use of electromagnetic locks may be restricted by local authorities such as your local building inspector and/or fire marshall. It is wise to check with these authorities before installing an electromagnetic lock. System OverviewTo install the most basic electromagnetic locking system on an out-swinging hollow metal commercial door and frame you need the following: The electromagnetic lockA way inA way outA power supply The electromagnetic lock is an appliance. It unlocks when you shut off the power. Therefore the means of entry and egress will be swtiches of some form or other. Means of entry could be: A key switchAn access control device like a card reader or keypad A remote as for a garage door openerYour choices for means of egress are limited by national, state and local life safety code. They could be: A mechanical push bar with a mechanical switch insideA pushbutton with pneumatic time delay clearly marked "Push to Exit" right next to the doorAn exit sensor with redundant pushbutton Your local Authority Having Jurisdiction (AHJ) may require that your power supply be connected to the building fire alarm so that in the event of an alarm, the panel can unlock the electromagnet. In any case you need a power supply with sufficient capacity to power your electromagnet. System ExamplesA simple electromagnetic locking system using products by Schlage Electronics might include: 1 each M490 electromagnetic lock 1 each PS902 power supply 1 each 653-05 key switch 1 each 621RD EX DA exit pushbutton A simple electromagnetic locking system by Securitron might consist of: 1 each M62 electromagnetic lock 1 each BPS-24-1 power supply 1 each DK-26SS keypad 1 each XMS exit sensor 1 each EEB2 redundant exit pushbutton Wiring the Electromagnetic Locking SystemIn the simple diagram above, you can see that the electricity travels in an unbroken loop. It starts at the "+" (positive) terminal of the power supply, travels through the exit and entry switches, into the positive terminal of the magnetic lock, and out through the negative (-) terminal of the mag back in through the negative terminal of the power supply. Because the loop in unbroken, we know the magnet is locked. If the loop is broken anywhere along the line, the magnet will be unlocked. When either of the switches is activated it breaks the loop and deprives the magnet of power, leaving it unlocked. NOTE: ALWAYS turn the magnet on and off via the positive terminal. Using the negative terminal could cause residual magnetism, a situation where the magnet does not immediately release when powered down. The exit switch could be a palm button, touch bar or motion sensor. The entry switch could be a key switch, keypad or other access control device. You could also use a wireless receiver and transmitter to control break or make the loop. Controlling an Electromagnetic Lock WirelesslyIn the above illustration I have substituted a wireless receiver and transmitter for the exit and entry switches in the previous drawing. Following the loop that powers the lock, electricity travels from the positive terminal of the power supply to the Common (C) terminal on the wireless receiver, then out of the receiver through the Normally Closed (NC) terminal to the positive terminal of the magnet. ("Normally Closed" means that the switch is in the closed position unless it is told to open by the wireless transmitter.) The electricity completes its loop by exiting the magnet by the negative terminal (-) and making its way back to the power supply. Notice that an additional pair of wires is needed to power the wireless receiver. When the wireless transmitter is activated the state of the relay on the wireless receiver is changed - that is, the normally closed terminal is changed to open. NOTE: ALWAYS turn the magnet on and off via the positive terminal. Using the negative terminal could cause residual magnetism, a situation where the magnet does not immediately release when powered down.

Ruby is upset about this arrangement and continues to wear the key to her old home on a chain around her neck. After learning she will be transferring to a new high school, Ruby attempts to run away but is found out. Nate Cross, Jamie and Cora's next-door neighbor, covers for her. Over the span of the story, Ruby slowly becomes closer to Nate. As Ruby adjusts to her new life, she learns Cora had not been avoiding her; in fact, Cora had been trying to rescue Ruby from their mother but had always been stopped. Ruby feels overwhelmed with all this, so she skips school to take alcohol and drugs, and later finds herself in Nate's car when he picks her up. Ruby comes home to a furious Jamie, who accuses her for being ungrateful to him and her sister. Having seen resemblances between herself and her mother that night, Ruby becomes determined to change her ways. One of Nate's clients, a high-strung woman named Harriet, offers Ruby a job at her jewelry store in the mall. Harriet's business booms after a line of key-shaped pendants, inspired by Ruby's necklace, becomes an instant hit. Harriet struggles with a conflict of her own: Because of her independence, she is reluctant to form a relationship with Reggie, who owns the kiosk next to her. Throughout the story Ruby becomes suspicious about Nate's father, and eventually learns that he abuses Nate. Nate is defensive about this, and that leads to them fighting and breaking up. One day, Cora and Jamie inform Ruby that the police had found her mother unconscious in a hotel room and was sent to a rehabilitation center. Later, Ruby finds out that Nate has run away, but finds him in an apartment room that she and Nate had visited while she was tagging along with him on his job. Ruby drives Nate to the airport when he decides to leave his father to live with his mother. After a sudden realization, she takes the key to the yellow house off its chain, replaces it with the key to Cora and Jamie's house, and hands the necklace to Nate. At the end of the school year, Ruby gives her English report on the meaning of family. For evidence, she shows two pictures, both of family. The first was of Jamie's huge family, while the second was taken at Ruby's eighteenth birthday party. After trying for months, Cora learns she is finally pregnant, and Ruby is accepted to the same university as Nate. She wants to write a letter to her mother, but not knowing what to say, simply mails a copy of her acceptance letter. At the end of the novel, she stands in the backyard, and as Cora and Jamie are calling for her to leave for her graduation, she takes out the old key to the yellow house from the pocket of her robe and drops it into the koi pond. Sarah Dessen conducted an interview with the blog The Sarah Dessen Diarist. RUBY chose abuse and neglect as a key theme as she "...was really interested in taking on a different type of narrator. Most of my girls are from upper middle class families, living in pretty solid environments. I was intrigued by taking a girl who WASN'T like that at all and dropping her into this whole new world. I liked the idea that you'd think it would solve all her problems—having a roof over her head, money, a family—but that it actually brought up a whole other set to deal with. Also, I liked the idea of my narrator having to sort of "save" someone else in order to save herself." Another key theme was family. It started out with Ruby not knowing the true meaning of family, only thinking that it meant people related by blood or marriage. So in Ruby's mind, the only family she had was her mother and her sister. But by the end of the book, Ruby realized that family is not only relatives, it's everyone who takes care of you, anyone who you trust, anyone who loves you. The concept of the English project sprung from her want to "...focus on the idea of family, and I thought it would be an interesting way to get Ruby thinking about it without it seeming too forced. Plus I really liked the idea of how everyone would have different definitions for the word, and in giving them, they'd be sort of defining themselves, as well." The song, Angel of Montgomery, allowed Dessen to "...get down the character of Ruby's mom. There's a certain sadness, and tiredness, in that song, and the woman speaking in it, and it really reminded me of what I was trying to/444455 to with Ruby's mom. I often will have a song that brings to mind a character, or helps fill them out a bit." The interview went into further detail with questions regarding character choices and inspirations for themes.
