The “One-Box Solution” for Cylindrical and Mortise Locks

Sept. 3, 2013
Trine’s 4100 Series electric strikes include the four most used faceplates to make specifying and installing easy.

Trine’s patented 4100 fire rated electric strike is designed for use with cylindrical locks and mortise locks without deadbolts. The 4100 electric strike’s operational life exceeds 1,000,000 cycles, according to Trine. The static strength holding force is 3250 lbs, and there is 70 ft-lbs. of dynamic strength.

It meets or exceeds the ANSI/BHMA A156.31 Grade 1 requirements. These electric strikes are Warnock Hersey recognized for UL10C, Fire Tests of Door Assemblies. According to Trine, the 4100 electric strike will receive the 1034 Burglary Listing after August 2013.

The non-handed Trine 4100 electric strike is manufactured of stainless steel, as is its 3.19" long keeper. This low profile electric strike has a 1-3/8" backset that can accommodate ½" sheetrock penetration requirements.

The strike’s locking mechanism is "spring-less; “in its place, a gravity-fed locking member controls the release of the keeper. When the Trine 4100 Fail Secure electric strike is mounted into the jamb, the locking member slides to the vertical down position. When the locking member is vertically down, the keeper is locked, retaining the lock’s extended latch. Because the Trine 4100 is non-handed, there are two vertical down positions, one for left hand and one for right hand doors.

Two solenoids are used to raise the gravity-fed locking member to the unlock position, which releases the keeper. Each solenoid’s operation is specific to the hand of the door. When the electric strike is installed into the jamb, the lower solenoid (when powered) lifts the locking member out of the locked position.

Fail Secure operation of the Trine 4100 momentarily powers the solenoid, retracting a portion of the armature into the solenoid. This action raises the locking member to the keeper release position. In the unlocked condition, the latch swings the keeper out of position as the door is swung open. The spring-loaded keeper swings shut once the latch has exited. When no power is provided, the keeper remains in the locked condition, kept in place by the gravity-fed locking member.

Note: A Fail Safe Trine 4100 Electric Strike is available. However, the fire listing for all fire rated electric strikes becomes void when using the electric strike in a fail safe operation.

The Trine 4100 Electric Strike can be configured for 12 or 24VDC and 12 through 24VAC. Current requirements for the 4100 Series Electric Strike are:

  • 12VDC @240mA*
  • 12VAC @210mA
  • 24VDC @114mA
  • 24VAC @420mA

The 12VDC electric strike can be operated using PoE (Power over Ethernet).

A Direct Current (DC) electric strike does not buzz when powered. The buzzing occurs when the electric strike is powered by Alternating Current (AC).

The voltage configurations are determined by which of the two quick connect socketed wire assemblies is installed. Three-wire quick connect socketed wire assemblies extend from each end of the Trine 4100 strike body. The wires are blue, red and brown. Depending upon which wire assembly is connected the current requirement is either 24VDC (blue wires) or 12VDC/12-24VAC (white wires). Connections for the white wires are the red and brown assembly wires extending from the electric strike. The blue wires connect to the red and blue assembly wires.

Important: No matter the handing of the door, the bottom wired connector operates the proper solenoid. The top wired connector is never used.

The Trine 4100 electric strike has eight faceplate choices, of which the four provided faceplates cover more than 90 percent of the cylindrical and mortise locks (without deadbolt) when installed into a hollow metal opening where the fire rated opening equipped with an 4-7/8" by 1-1/4" ANSI strike plate.

The four provided faceplates are:

  1. Centered Cylindrical (CC) faceplates accommodate up to a ¾" throw latch. In addition, the 4100 can accommodate dead bolt type locks with up to a ¾” throw bolt. The 1-23/32" opening for the latch is on the horizontal centerline of the strike faceplate. As an option, the CCRD ANSI 4 - 7/8" centered faceplate has radiused corners.
  2. Mortise High Offset (MHO) faceplates accommodate Accurate, Arrow, Best, Corbin Russwin, Falcon 1992M Series, Sargent 7800, 8200 & 9200 Series and Yale 8800 Series mortise locks. The 1-15/32" opening for the latch is 19/32" below the horizontal centerline of the strike faceplate.
  3. Mortise Medium Offset (MMO) faceplates are designed for Baldwin, Marks and PDQ mortise locks. The 1-11/32" opening for the latch is 29/32" below the horizontal centerline of the strike faceplate.
  4. Mortise Low Offset (MLO) faceplates are designed for for Jackson, Sargent 7700 & 8100 Series and Schlage L Series mortise locks. The 1-11/32" opening for the latch is 1-1/64" below the horizontal centerline of the strike faceplate.

To ensure proper door alignment, two latch spacer shims with mounting screws are included. The shims are installed onto the inside face of the keeper. Their purpose is to move the latch (door) further within the jamb. Each shim is approximately 11/64" thick.

For retrofit applications, the Trine 4100 electric strike comes with a rigid stainless steel frame trim skirt, which has the same finish as the electric strike. The skirt covers any cut lines that are not of the dimensions required for the 4100 body. As an option, the Competitor Cutout Trim Skirt (CCTS) is wider than the included trim skirt. The CCTS covers the gap when retrofitting. For a retrofit list, contact the factory. 

Additional options include a 12 or 24VDC Piezo Buzzer that sounds when DC voltage is applied. In addition to the 4100RS, Fail Safe configured electric strike; latchbolt monitor (4100LB) will be available as an option beginning around October 2013.

When installing an electric strike, it is extremely important that the proper gauge wire is used for the length of the wire run. This prevents voltage drop. See the wiring chart provided by Trine when wiring a 4100 electric strike.

The Trine 4100 electric strike is available in six architectural finishes. Trine uses the Physical Vapor Deposition (PVD) process, which creates a durable, corrosion and tarnish resistant finish. The finish choices are:

  • US3 Bright Brass
  • US4 Satin Brass
  • 10 Satin Bronze
  • 10B Dark Bronze
  • 32 Polished Stainless Steel
  • 32D Satin Stainless Steel

To maintain finish consistency, the 4100 faceplates, strike body, mounting screws and trim skirts match the finish.

The stainless steel  Trine 4100 Electric Strike is a new addition to the Trine "one box solution," having the parts necessary for 12 through 24VAC or 12-24VDC applications. Four included faceplates satisfy most retrofit applications. A frame trim skirt covers cut lines to provide a clean installation. The "one-box solution" can eliminate problems, enabling a one trip sale and installation.
