FS90 OVERLAY 110/120VAC

Description

120VAC FS90 overlay for all 110/120VAC controllers.

Designed to correct door operation on PHII mode with the in car stop switch off.

Small package (4.5″x3″).  These are usually mounted in the controller.

ANSI 94V-0 rated board. Meets A17.1 requirements.

Very fast install if signals are all present in the controller or on the car.

This board expects active high inputs for  PHII, and DZ inputs, but the KEY/HAT input may be Active Low/High (jumper selectable).

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 if it remains on when the car is called to the fire floor, and the doors fully open.
