Won’t be cheap …
what system do you have?
Pyronix UR 2 and HUD-WE ,but as mentioned this would not be cheap.
You can program the keypad with a panic function by pressing 1&3 together. You will need the engineer code for this.

Needs to be fail safe,
Does the wireless panic button send regular "No panic link test" messages at regular intervals ?
Will the panel react if these test messages fail to arrive at the panel ?
Much easier to be fail safe when it is a wired panic alarm.
And reed switch’s in panic buttons can stick …..
True, two in series reduces the risk of the panic button not going open circuit
There are alternatives to reed switches such as forced disconnection switches where an insulator is forced between the two contacts
A very simple but almost 99% fail safe "switch" is achieved when pressing the button snaps a fragile wire ( blue blocks are terminals )
Do they work with the UR2-WE now?
The panel will ( should ) show "No Panic Activated" which proves the loop is intact,
One has to design the item such that one can be certain the wire will be snapped if the red plunger is pressed.
A bit like testing a box of matches. test each match before sale or ensure the matches are manufactured correctly.
Bernard stop living in fantasy land pa buttons have been reed switches or micro switches for the last 30 years
You can wire it in series with a resistor, the panel tests continuously to ensure a certain resistance is presented, within a tolerance, if the tests fails, it triggers an alarm. Another way is to have a diode in series in the button, feed it with ac - dc coming back proves the button, nothing or ac coming (shorted wires) back triggers the alarm.
