Description
48VDC POSITIVE GROUND FS90 overlay.
Designed to correct door operation on PHII mode with the in car stop switch off.
Very small package (2 1/8″x 3 5/8″). Easily mounted in car operating panels, or controllers.
ANSI 94V-0 rated board. Meets A17.1 requirements.
Very fast install. Installs can take an hour or less in some cases.
This board is designed for Dover Wire relay or other positive ground controllers. We recommend that you have us mark up sections of your prints, and provide instructions, but a good technician should be able to interface it.
Any voltage stop switch and Call Cancel button may be used (contacts rated for .5A). Higher duty relays are easily interfaced for bigger loads.
Adhesive standoffs are provide, just peel and place the board to mount it.
The board monitors PHI so that a PHII switch left in the on position with the car on normal will not override the stop switch and cause entrapments.
PHI monitoring is VERY flexible, and can be monitored using just the in car fire hat jewel in many cases, or using smoke detector and Hall PHI key switch inputs if needed. To use the Fire hat, it must remain on when the car is called to the fire floor, and the doors fully open.
