Hat on elevator recall

No.
It lights up when the recall (primary or secondary),is active. It lets the car occupants know the building is in alarm, but, not the shaft or machine room smoke. It is to flash when one of those are in alarm.
Of course, every state/AHJ has their own little quirks.
I would check with the elevator company before doing anything. They need be the ones deciding how its supposed to work.

i thought the fire hat comes on to notify FF that there is a fire in elevator equipment rm, or shaft.
No it must flash if there is an alarm in the shaft or mechanical room. I do not have the code reference,atop lazy to find in on a Sunday. but I stand by that.
Also found this out in an article:
If you enter an elevator and find that the fire hat symbol on the main car operating panel is illuminating intermittently (flashing), it indicates that a smoke or heat detector, or other fault, has been activated in the elevator machine room or hoistway containing equipment that services that group of elevators.

Elevator Fire Service Summary
Elevator Fire Service Summary
Fire Alarm requirements for elevator fire service:
NFPA 13, NFPA 70, NFPA 72, ANSI / ASME A17.1 A17.3
Fire fighter's hat will turn on steady when the elevator car is place in bypass by with a service key.
Phase I Fire Service
Elevator recall smokes installed in elevator lobbies on every floor.
Activation of a smoke detector will send the car to the primary floor.
Activation of the smoke detector on the primary floor will send the car to the secondary floor.
Phase II Fire Service
When a smoke detector in the elevator hoist-way or equipment room activates the Fire Fighter's Hat will flash
If the hoist-way or equipment room is sprinklered, then there must be a 135 degree rate of rise or rate compensation heat detector installed within 24" of each sprinkler head and set for a lower trip temperature than the sprinkler head. When any heat detector is activated, primary elevator power shall be shut down via a shunt trip breaker suppling the elevator equipment. The shunt trip power must be 120VAC and must be supervised by the fire alarm system.
Every Elevator will need the following Fire Alarm devices:
Smoke detector in every elevator lobby
Smoke detector in the elevator equipment room
Smoke detector in hoist-way if permitted
Relay for Primary Recall
Relay for Secondary Recall
Relay for Flash Hat
Relay for Shunt Trip
Monitor or zone for Shunt Trip Power Fail
As always check with AHJ. Some AHJs require the shunt trip to be delayed 30-60 secs.
