Overview

The GK300 series electric strikes are ANSI-sized devices designed for use with locksets, specifically those with a spring latch, and can accommodate keeper depths of up to 12 mm for in-swinging doors. These units are suitable for installation in most hollow metal frames and aluminum frames, with stainless steel plates ensuring strength and longevity. The strikes are designed to be both automatically and manually operable.

Function Description

The GK300 series electric strikes are designed to secure doors by interacting with a lockset's latch bolt. When the door is closed, the strike's keeper holds the latch bolt, preventing the door from opening. To unlock the door, the strike's keeper retracts, allowing the latch bolt to disengage. The series includes models compatible with both spring latch and latch-bolt locks, as well as a model for night latches.

A key feature is the "Version Changeable" design, which allows the electric strike to be easily switched between fail-safe (power to lock) and fail-secure (power to open) modes in the field. This unique design helps distributors manage inventory and sales by adapting to varying needs and requirements.

For latch-bolt locks, the strike interacts with both the nib and the latch bolt. When the door closes, the nib deadlatches the latch bolt, and the latch bolt slides into the strike keeper's cavity, preventing the door from being opened or "jimmying." This security feature is particularly suitable for outward-opening doors.

Important Technical Specifications

Usage Features

The GK300 series offers various models to suit different door frames and lock types:

  • GK300/GK300M: For hollow metal frames with spring latches.
  • GK301/GK301M: For wood frames with spring latches.
  • GK310/GK310M: For hollow metal frames with latch-bolt locks.
  • GK311/GK311M: For wood frames with latch-bolt locks.
  • GK350: For hollow metal and wood frames with night latches (surface mounting).

The "M" suffix in model numbers (e.g., GK300M) indicates a switch-monitored version.

Installation Types:

  • Flush Mounting: For GK300, GK301, GK310, GK311 series in hollow metal or wood frames.
  • Surface Mounting: For GK350 series.

Optional Accessories:

  • Lip Extension Brackets (LP-025, LP-050): Available for wide jambs, extending the strike's reach to accommodate different door frame configurations.

Latch Monitoring Output:

Models with the "Sensor Switch monitoring output" function provide feedback on the lockset's status:

  • When the door is opened, the sensor switch connects the "green - yellow" wire.
  • When the door is closed, the sensor switch connects the "green - blue" wire. This output, rated at 2A@125V, indicates whether the lockset is locked or unlocked.

Unique Narrow Strike Base (GK300-9 series):

The GK300-9 series features a narrow strike base designed for streamline door jamb solutions. These strikes are also designed for use with door latches, having up to 12 mm keeper depth for in-swinging doors. An added indent to the latch helps overcome problems with some mortise locks sticking on opening.

Maintenance Features

  • Long Life Solenoids: Special solenoids are designed for strength and long life, guaranteed for an operating lifetime of at least 1,000,000 times, minimizing the need for frequent replacement.
  • Robust Construction: Stainless steel plates ensure strength and long life, contributing to the device's durability and reducing maintenance requirements.
