Whilst I agree, and no longer use scanny wireless for the very reason its 1 way, its pretty reliable and have never had a system using wireless as the E/E zone fail to start the E/E, so on that basis I'd say it's reliable enough, just plainly not as secure, as 2 way. Back to you, this all depends if the fire exit doors are regularly opened or rarely opened if at all. If only ever used in a fire or once or twice a year, then set the zone to 24hour. When the alarm is unset, you'll still get a tone from the speaker (a noisy one) that will need a code or fob to reset. But no bell. And you could fit a keyswitch based shunt to the door itself to override the alarm when required. I don't think the 9751 does zone follow as an output type, otherwise that would be the ideal solution.
