Sargent Surface Vertical Rod Exit Device Provides Higher Level of Access Control

Gaining access into the Information Technology Suite requires presenting an authorized badge and rotating the trim lever, the same procedure used for gaining access through the corridor doors.


The new exit device was installed directly over the removed device mounting holes using the inactive door exit device as a guide. The device was ordered to size and fit without modification of the pushbar. New holes were drilled to accommodate the ET Control Trim, the center case and the mounting bracket. It is always important to measure the length needed for the top rod and the exit device is not always installed in the specified location.

To ensure a proper installation, a level was placed onto the rail prior to drilling the mounting bracket holes. All holes were drilled and tapped.

The exit device was mounted onto the antechamber door. The distance between the top case and the chassis assembly was measured. For this installation, the top rod had to be cut to length. Once the rod was cut, it was screwed into the top case and backed off about one and a half revolutions. Cutting the rod required a new hole for the rod adjustment pin. The hole was drilled in place and the pin installed.

The rod guide provides protection against being bent or pulled out from the device. The rod guide base was positioned beneath the rod to set the location. Once placed behind the rod, it was slid to the halfway point between the device and the top case. Then we drilled and tapped the two holes for mounting the guide. The guide base was slid out from behind the rod and secured using the two mounting screws.

The location for the top strike was determined and marked using the latch as the guide. The four mounting holes were drilled and tapped. The top strike was installed. The mechanical operation of the exit device was tested to ensure proper operation. Adjustments were made as necessary.

To provide remote wireless release of the electrified trim, a BEA 433MHz Series digital transmitter and receiver were included in the installation. The inside range of this release is approximately 100-200 feet with minor obstructions. The 433MHz radio frequency signal can go through most walls.

The BEA 10RD433 receiver was installed in the wall behind the badge reader. The receiver operates on 24VDC. Since the wall separated the antechamber from the reception area, it would be able to receive the signal from the BEA one button transmitter, part number 10TD433HH. The transmitter is battery operated. The transmitter was programmed to the receiver.

The electronic operation of the exit device trim, badge reader, receiver and transmitter were tested to ensure proper operation. Now gaining access into the Information Technology Suite requires presenting an authorized badge and rotating the trim lever, the same procedure as gaining access through the corridor doors.

Important: Prior to purchasing and installing electromechanical access control devices, contact the Local Authority Having Jurisdiction (LAHJ) to ensure the products to be installed meet their criterion.
