Metal enclosures
Application.
The 5402 and 5422 shock sensors eliminate the need for costly lined boxes or placement of security system controls in a vault for UL mercantile applications. To meet UL requirements, a tamper switch is required. >
Installation.
To protect metal enclosures, use the self-powered 5402 or 4-wire 5422 shock sensor. Mount the sensor on the side wall on or near the hinge. If the hinge runs the length of the side, center the sensor vertically ( Figure26 ). If the enclosure has multiple hinges, mount the sensor next to the hinge nearest the middle of the enclosure.To mount the sensor, do the following:1.Peel back the paper from one side of the adhesive tape pad and press it onto the back of the sensor. The tape pad must be flat against the plastic case.2.Use a 50/50 solution of isopropyl alcohol/water to clean the mounting area. Dry the mounting area, then peel the backing paper from the tape pad and press the sensor against the metal. The tape will fully adhere within 24 hours.3.Wire the sensor (if applicable) to the loop according to wiring instructions.4.To test the sensor, use the metal shaft of a medium-size screwdriver to lightly scrape back and forth against the edge of the metal enclosure farthest from the sensor ( Figure26 ). If the sensor does not respond, a second sensor may be required. >
