Keying Devices and Systems
• Warded locks– the keyway is open and can be seen through
• Disc tumbler locks– Used as desk locks, files locks, and padlocks
• Pin tumbler– keyway, which is irregular in shape, and the key, which
is grooved on both sides – can be master keyed
• Lever locks– used in safe deposit boxes and are for all practical
purposes pickproof

Removable Cores
• Used where locks are changes often• Made to be removed if necessary
with a core key, allowing a new core to be inserted
![Page 8: Unit 4 Seminar/Unit 5 Review Case Study: ABC Valve Plant Al Dauser, CPP, CFI Adjunct Professor](https://reader035.vdocuments.mx/reader035/viewer/2022062314/56649e7e5503460f94b81b13/html5/thumbnails/8.jpg)
Keying Systems• The change key
– One key to a single lock within a master-keyed system• The submaster key
– Will open all the locks within a particular area or grouping in a given facility
• The master key– Where two or more submaster systems exist, a master
key system is established• The grand master key
– One that will open everything in a system involving two or more master-key groups

Other Operating Mechanisms for Access Control
• Combination locks– have three dials that must be aligned in
the proper order before the lock will open
• Code-operated locks– opened by pressing a series of
numbered buttons in the proper sequence
• Card-operated locks– presenting a card and code to open lock
![Page 10: Unit 4 Seminar/Unit 5 Review Case Study: ABC Valve Plant Al Dauser, CPP, CFI Adjunct Professor](https://reader035.vdocuments.mx/reader035/viewer/2022062314/56649e7e5503460f94b81b13/html5/thumbnails/10.jpg)
Advantages of Access Control Systems
• a. Security staff no longer need to spend hours rotating key cores and keeping detailed logs.
• b. Card keys can be programmed to function in a variety of ways.
• c. Lost cards can be deactivated in a matter of seconds.
• d. The systems often allows the hotel to keep track of the time and number of entries at a given site

Locking Devices
• Electromagnetic locking devices – hold doors closed by magnetism
• Double-cylinder locking devices – installed in doors that must be secured from both sides,
requiring a key to open them from either side– most common application is in doors with glass panels
• Emergency exit locking devices – panic-bar installations
![Page 16: Unit 4 Seminar/Unit 5 Review Case Study: ABC Valve Plant Al Dauser, CPP, CFI Adjunct Professor](https://reader035.vdocuments.mx/reader035/viewer/2022062314/56649e7e5503460f94b81b13/html5/thumbnails/16.jpg)
Locking Devices (cont.)• Recording devices
– provide for a printout of door use by time of day and by the key used
• Vertical throw devices – lock into the jamb vertically instead of the usual horizontal bolt
• Electric locking devices – activated remotely by an electric current that releases the
strike and thus permits entrance • Sequence locking devices
– designed to ensure that all doors covered by the system are locked
![Page 17: Unit 4 Seminar/Unit 5 Review Case Study: ABC Valve Plant Al Dauser, CPP, CFI Adjunct Professor](https://reader035.vdocuments.mx/reader035/viewer/2022062314/56649e7e5503460f94b81b13/html5/thumbnails/17.jpg)
Effective Surveillance Systems
• Should produce an identifiable image of persons engaging in criminal behavior
• Sequence cameras record still pictures at regular intervals
• Motion picture cameras using high-speed 16 mm film and fast shatter speeds can be set up to take pictures in normal light
• CCTV systems coupled with recording equipment or computers should be used
![Page 18: Unit 4 Seminar/Unit 5 Review Case Study: ABC Valve Plant Al Dauser, CPP, CFI Adjunct Professor](https://reader035.vdocuments.mx/reader035/viewer/2022062314/56649e7e5503460f94b81b13/html5/thumbnails/18.jpg)
Technological Advances In CCTV
• Reduced size of the camera• Reduced price of color cameras• Improved reliability of color cameras• “Starlight” cameras – allow for good video reproduction in low
light situations
![Page 19: Unit 4 Seminar/Unit 5 Review Case Study: ABC Valve Plant Al Dauser, CPP, CFI Adjunct Professor](https://reader035.vdocuments.mx/reader035/viewer/2022062314/56649e7e5503460f94b81b13/html5/thumbnails/19.jpg)
Replacing CCTV Camera’s
• Variables to be considered during a site survey– Is the camera to be visible and used as a deterrent to
crime or hidden and used in civil or criminal prosecutions?
– What effect, if any, will the sun have on the operation of the system?
– Where is the best location for a camera?– Should the placement of the camera be high?– What type of lighting is in use?
![Page 20: Unit 4 Seminar/Unit 5 Review Case Study: ABC Valve Plant Al Dauser, CPP, CFI Adjunct Professor](https://reader035.vdocuments.mx/reader035/viewer/2022062314/56649e7e5503460f94b81b13/html5/thumbnails/20.jpg)
Old Construction
• Difficulties– exterior fire escapes– old and frequently badly worn locks– common walls– roof access from neighboring buildings– unused and forgotten connecting doors
![Page 21: Unit 4 Seminar/Unit 5 Review Case Study: ABC Valve Plant Al Dauser, CPP, CFI Adjunct Professor](https://reader035.vdocuments.mx/reader035/viewer/2022062314/56649e7e5503460f94b81b13/html5/thumbnails/21.jpg)
New Construction
• Modern construction creates offices that are essentially open-top boxes
• Any given floor of a building has a crawl space that runs from exterior wall to exterior wall
![Page 22: Unit 4 Seminar/Unit 5 Review Case Study: ABC Valve Plant Al Dauser, CPP, CFI Adjunct Professor](https://reader035.vdocuments.mx/reader035/viewer/2022062314/56649e7e5503460f94b81b13/html5/thumbnails/22.jpg)
The ABC Valve Plant
• Assess the potential risks and provide solutions for the ABC Valve Plant.
• Each proposed change should be supported in terms of why it is needed.
• Include references to the security systems and procedures you referenced in the course.
• Do not attempt to redraw the facility. (Do not cut and paste the diagram into your case study).
![Page 23: Unit 4 Seminar/Unit 5 Review Case Study: ABC Valve Plant Al Dauser, CPP, CFI Adjunct Professor](https://reader035.vdocuments.mx/reader035/viewer/2022062314/56649e7e5503460f94b81b13/html5/thumbnails/23.jpg)
ABC Valve Plant• Some students in the past have found this to be a difficult project. • The key is to use the textbook as your guide since it touches on all
the problems listed on the assignment. • Physical security, locks, lighting, card access, alarms, guards, fire,
hiring, visitor control, CCTV, shipping/receiving, etc. • Do not cut and paste the site plan into your case study. • A suggestion is to follow a good/better/best format. The problem
with consultants is that they do not necessarily have a budget to follow.
• Does the cost of the upgrades outweigh the benefit of implementing them??
• Do you get a return on your investment (ROI) in a short period of time (3 years??) Also do not forget to mention controls for raw materials, finished goods, and tools.

The ABC Valve Plant
• Three to five page in length (this does not include title and reference pages)
• The paper should contain a cover page and a list of references in APA format.
• All internal citation of outside sources plus the listing of all references should also adhere to APA format.
• All text pages should be double-spaced and in 12-point font.
