Abstract

An access control device including an electromagnetic lock module for selectively locking and unlocking a door in a door frame is provided. The access control device provides a lower profiled electromagnetic lock module to improve the aesthetics and functionality of the module, supports and integrates modern accessories such as CCTV, CCD cameras, passive motion detection with automatic background correction, digital notification display, automatic source voltage selection, door and lock status indicators, and ease of installation. The present invention further provides components and circuitry to enable connection of the electromagnetic control module to 12 or 24 volts DC or to an unfiltered rectified AC power supply.

First claim

What is claimed is:

1. An installation guide system to aid in properly locating relative positions of a first cooperating component and a second cooperating component of a door latch system on a door and a door frame during installation, said installation guide system comprising:
a) said door latch system including said first cooperating component and said second cooperating component, said first cooperating component including a mounting hole; and
b) an installation guide including:
i) a template for placement on one of said door or said door frame, said template being sized generally the same as said first cooperating component, said template including a hole location marked on said template in the same position as said mounting hole on said first cooperating component; and
ii) a spacer separable from said first cooperating component and said second cooperating component, wherein said spacer is configured to properly locate said second cooperating component on the other of said door or said door frame relative to said first cooperating component during installation of said first cooperating component and said second cooperating component on said door and said door frame, and wherein said spacer is removable after installation.

2. The system of claim 1 , wherein said first cooperating component is a keeper plate.

3. The system of claim 2 , wherein said keeper plate is an anti-swivel keeper plate.

4. The system of claim 2 , wherein said keeper plate includes a hole defined therein, and wherein a roll pin is disposed in said hole.

5. The system of claim 1 , wherein said second cooperating component is an electromagnetic lock module.

6. The system of claim 5 , wherein said electromagnetic lock module includes a mounting plate.

7. The system of claim 6 , wherein said mounting plate includes a slot, and wherein said spacer is positioned within said slot.

8. The system of claim 1 , wherein said spacer directly contacts said second cooperating component during said installation.

9. A method of installing a door latch system, wherein the door latch system includes a first cooperating component and a second cooperating component, wherein the first cooperating component includes a mounting hole defined therein, and wherein the second cooperating component is mountable to one of a door or a door frame, the method comprising:
placing a template on the other of the door or the door frame, wherein the template is sized generally the same as the first cooperating component, wherein a spacer is separable from the first cooperating component and the second cooperating component, and wherein the template includes a hole location marked on the template that corresponds to the mounting hole on the first cooperating component;
engaging the spacer between the template and the second cooperating component;
aligning the spacer with the second cooperating component so that, when the door is closed within the door frame, the template is properly located on the other of the door or the door frame relative to the second cooperating component;
noting on the other of the door or door frame the hole location marked on the template; and
mounting the first cooperating component to the other of the door or door frame using the noted hole location.

10. A method of claim 9 , further comprising the step of removing the spacer from between the template and the second cooperating component.
