The HS1500 enclosure comes standard from the factory with a tamper switch installed. Should it become necessary to install a replacement

switch, refer to Figure 4 for the correct position of the bracket/switch and perform the following steps:

1. Remove the front cover.

2. Install the bracket/switch and secure with lockwashers and nuts.

The tamper switch comes with both a “Normally Open” and a “Normally Closed” contact.

For a “Normally Open” circuit, use the “open” and “common” terminals; for a “Normally Closed” circuit, use the “closed” and “common”

terminals.

Clean the Lexan window with a mild non-abrasive detergent in water and a soft cloth regularly to help maintain picture clarity. For a heavily

soiled window, use vinyl cleaner.
