2. From the non-hazardous side (Safe Area) of the EZ-SCREEN LPM, verify that the system cannot be muted and that
the light screen OSSDs turn Off and remain Off when the defined area is blocked.
Mute-Dependent Override (configuration options #5, #6, or #7)
1. Clear all mute sensors and the light screen; verify that the OSSDs are On.
2. Block (interrupt) the defined area of the light screen.
3. Verify that the OSSDs turn Off.
4. Block (activate) one or both of the mute sensors. The external mute lamp should be flashing.
5. With the light screen defined area and one mute sensor blocked, start the override by closing the RESET/OR1 input
and opening the OR2/ME input (within 3 seconds of each other).
6. Verify that the OSSDs turn On, and that the mute lamp, if used, is on steady.
7. Verify the OSSDs turn Off after 60 seconds when the Override timer expires.
8. Clear the light screen and all mute sensors.
9. Verify that the OSSDs turn On.
10. Open the RESET/OR1 input and close the OR2/ME input.
11. Verify that the OSSDs remain On.
Bypass Function (configuration options #3, #4 or #8)
1. Clear all mute sensors and the light screen; verify that the OSSDs are On.
2. Block (interrupt) the defined area of the light screen.
3. Verify that the OSSDs turn Off.
4. With the defined area blocked, start the bypass by closing the RESET/OR1 input and opening the OR2/ME input
(within 3 seconds of each other).
5. Verify that the OSSDs turn On, and that the mute lamp, if used, is on steady.
6. Verify the OSSDs turn Off after 5 minutes when the Bypass timer expires.
7. Clear the light screen.
8. Verify that the OSSDs turn On.
9. Open the RESET/OR1 input and close the OR2/ME input.
