S-18 ACCESS CONTROL TRENDS AND TECHNOLOGY 2016 JULY/AUGUST electrified by replacing the outside operating trim, allowing the door to be opened by the external lever han- dle when electronically unlocked. • E x treme Ser vice: High -value sites, dangerous neighborhoods, and some military or research applications may require more extreme vandal or attack resistance measures. New York-based Securitech has developed highly van- dal resistant exterior electronic trim for many lock and exit device appli - cations, as well as ex treme ser vice multi-point locks. Sargent & Greenleaf is also well known within the govern- ment security circles. • Solid Glass Doors always present a challenge for the Integrator. Out- swinging doors, using top mounted electric strikes or magnets tend to be reliable for after- hours securit y. Double swing doors are best secured manually, using an alternate route for after-hours access. • Storefront Doors: A glass door with a narrow-stile aluminum frame is the ove r w h e l m i n g f avo r i te ret a i l c o n - figuration. Touch Sense Bars, along with a top - mounted magnetic lock, have been popular for some time. In recent years, Adams-Rite and several others have developed exit device o ptio ns w ith ele c tr ic l atc h retr a c - tion or electrified exterior trim. RQE options are included. • Sliding Glass Doors present some i nte re s t i n g c h a l l e n g e s . El e c t ro n i c activation is a standard option, but t h e b re a k- a w a y p a n i c - ex i t p a n e l s once opened, are often left unse - cured. In one case, these emer- gency panels were secured with a h o o k - b o l t . A n a f t e r - h o u r s e m e rg e n c y e g re s s d o o r w i t h electrified exit device was then installed – with the enthusias- tic blessing of the Authorit y Having Jurisdiction. • Frame Mounted devices can include: Locking solenoids, "Hi -Tower" frame mounted latch release from SDC, and Unlatching strikes from Secu- ritron. These can eliminate the need for a power transfer cord or hinge. Power Options Low current draw has gained increased importance in recent years. In the early days, electric latch retrac- tion on exit devices required powerful solenoids. Twelve to 16 amp inrush was common. A marginal power sup- ply or inadequate wiring might work sometimes but often failed to sup- ply adequate current when binding occurred. Present day locks and exit devices often use small motors with extremely low current draw to retract the latch, or hold it open. Corbin-Russwin and Sargent divi- sions of ASSA/ABLOY now supply electrified locks with power consump- tion as low as .3 watt. Securitron offers an "Inductive Coupling" power trans- fer, producing 250 mills at 24VDC. The Best Division of Stanley and Schlage division of Allegion have announced a number of low-current options and pre- wired quick connectors. Power over Internet is becoming an increasing reality in many applica- tions. The implications for the Integra- tor are that many good things are hap- pening to make installations better, faster and cheaper. Re-working fire rated doors: It is important to understand the differ- ence between panic exit and fire rating requirements. Panic bars (exit devices) allow unimpeded exit. A panic-exit device may or may not be listed for a fire rating. Modifications to fire-rated open- ings are required to be done by certified installers, in accordance with specified procedures. The good news is that exterior doors are seldom fire-rated (unless in close proximity to another structure). In most cases, electronic access con- trols are only applied to fire-rated openings that separate containment zones within a given building. Where required, Cross-Door Raceway drill- ing tools and training are available from Security Door Controls (SDC), and from Lockmasters. The good news is that you now have many elegant and reliable elec- tromechanical options that can give you a competitive edge. ■ High-Security Lock Assembly Unlatching Electric Strike
