Electronics for the Yale eBOSS electronics are located on the secure side of the door. The vandal resistant, stainless steel 12-button keypad is located on the exterior side of the door in a separate escutcheon.
Yale has introduced the eBOSS Series of standalone, battery powered, electronic access control cylindrical locksets for exterior and interior applications. The "BOSS" in eBOSS stands for Battery Operated Security Solution. The eBOSS E5400LN Series is a Grade 1 electronic lockset that meets or exceeds ANSI A156.2. This motorized lockset is designed to meet UL - cUL Fire Label for all door functions up to 3 hours and the accessibility guidelines of the Americans with Disabilities Act (A.D.A.). The Yale eBOSS is designed to operate as either as an electronic lock or a mechanical lock (using key override) configured to the Storeroom function. The eBOSS Series electronic locksets are available without mechanical key override.
The Yale eBOSS electronics are located on the secure side of the door. The vandal resistant, stainless steel 12-button keypad is located on the exterior side of the door in a separate escutcheon. The keypad is arranged in the standard telephone matrix. The keypad is positioned below vertical blinders, which are raised sides of the escutcheon. These blinders protect the pushbuttons and resist attempts to read the code entries. Vandalizing or destroying the keypad will not release the door. According to Yale, the circuit board is conformal coated and the circuitry is silicone sealed. The eBOSS can be installed in exterior applications without a moisture gasket.
The mechanical components of the Yale eBOSS are based on the Yale 5400LN Series lockset. The locksets are constructed of zinc dichromate plated cold rolled steel. They are equipped with patented Freewheeling Levers. When locked, the outside lever will rotate freely up and down without retracting the latch. These locks are equipped with stainless steel deadlocking latch bolts. The eBOSS is available with beveled or flat latch bolt having a throw of 1/2", 5/8", or 3/4".
The eBOSS is designed to be installed into a modified ANSI A115.2 series door preparation. Two additional cross bore openings are required for the wiring (1" diameter opening) and securing the electronics (3/8" diameter opening). The lockset's anti-rotational through-bolts (5/16" diameter opening) are located at the 6 and 12 o'clock positions. Latch bolts are available to accommodate a 2-3/4" or 3-3/4" backset. The eBOSS lock chassis is designed to fit doors from 1 -3/4" to 2-1/4" thick.
For this article, we will install the Yale eBOSS onto the supplied mount. New installations require a 2-1/8" diameter cross bore opening at the appropriate backset (2-3/4" or 3-3/4"). A 1" diameter edge bore opening is required for the latch bolt. Two 5/16" diameter cross bore openings are required for the through bolts. Two additional cross bore openings are required -- a 1" diameter opening for the wiring and 3/8" diameter opening to secure the keypad to the controller board assembly. For retrofits, drill the necessary openings to accommodate the installation of the components.
NOTE: When preparing the door, drill the cross bore openings from both sides to avoid splintering the face of a wood door. Always wear eye protection when operating electrical tools.
Step 1. Determine the hand of the door. If the lock chassis is not handed correctly, reverse the hand to accommodate the opening.
If the lock is equipped with a conventional lock cylinder, insert the key, rotate clockwise 70 degrees clockwise. Depress the retainer using the supplied tool. Slide the lever off. If necessary, rekey or replace the lock cylinder at this time.
Note: Lock cylinders designed for the eBOSS use a tailpiece that is 3/16" shorter than those supplied with the 5400LN Series locks. It is recommended to use the correct tailpiece with the eBOSS. If using a competitor's lock cylinder, a shell sleeve may be required.
