SDC 2490A Extra Narrow Concealed Mortise Bolt Lock Fail Secure Instruction Manual

INSTALLATION INSTRUCTIONS
2490A
EXTRA NARROW CONCEALED MORTISE BOLT LOCK
FAIL-SECURE

OVERHEAD INSTALLATION HORIZONTAL

1. Examine the top rail of the door for the most suitable location for the strike plate. Mark the door for the end of the strike closest to the lock stile, and make a corresponding mark on the header to line up with the first mark.

2. Locate the centerline of door thickness on the header and attach an adhesive cut-out template to the header. Lining it up with marks, center punch the tab-mounting screw locations, and counter-sink for #10 screw. Saw or rout out the cutout area. Continue to step 5.
   SIDEJAMB INSTALLATION VERTICAL

3. Examine the lock stile jamb for the point nearest the center of the door height, with space available for the lock and strike. Mark the door stile horizontal for the top end of the strike plate and make a corresponding mark on the jamb.

4. Locate centerline of door thickness on the jamb and attach adhesive cutout template to the jamb, lining up the top of the cutout with the horizontal mark on the jamb. Center punch the tab mounting screw locations and countersink for #10 screw. Saw or rout the frame cutout.

5. Attach the mounting tabs inside.

6. Attach power supply and access control leads to locking leads as shown on page 2. Handle the lock carefully; do not hang it by the wire leads. Insert wiring into the header cavity carefully so they do not interfere with proper locating of the lock in the cutout.

7. Insert lock. When installed overhead horizontally, the bolt end is nearest the lock stile. When installed vertically on the side jambs, the bolt must be at the top end of the cutout. Secure with #10-32 machine screw.

8. Using strike plate as a template, mark screw hole location and drill holes for screws supplied. Mortise as required. Attach strike.

9. The Automatic Relock Switch (ARS) is set for 1/8” clearance between the top of the door and transom bar or head jamb. Any additional gap may be compensated for by loosening the lock nut and turning the switch assembly clockwise until the proper adjustment is reached. Be sure to tighten the locknut when adjustment is satisfactory.
   

Easy installation or servicing

All Space Saver locks are easily installed in any existing entrance merely by mortising out a cut-out, attaching the wiring, inserting the lock, and bolting it into position with two attaching tabs. Cutting studs is no longer a problem or expense.

LOCK WIRING

NOTE: The SDC PR-1000 Power Regulator is included with the bolt lock. Although the solenoid is rated for continuous duty, continuously powering the solenoid will generate heat. Installing the PR-1000 reduces the power consumption of the bolt locks after activation of the lock, allowing for a heat reduction to the bolt lock, and increasing the life of the solenoid. DC voltage is recommended for improved heat reduction.

Solenoid Voltage Configuration:

ELECTRICAL DATA:
Dual Voltage Solenoid (2490A)
12VDC@ .9 Amp (max.)
24VDC@ .45 Amp (max.)
Continuous Duty
2490A (Without PR-1000):

2490A (Wiring w/ PR-1000; recommended):

PR1000 Input Voltage: 12/24 VDC/AC (+/-10%) DC voltage is recommended for optimal performance
