Generally, receive-only pagers, ordinary car key fobs (transmit only) and similar electronics can be admitted to most controlled areas, but must be cleared first. Two-way pagers, two-way car fobs, bluetooth devices, smart watches, etc are all obscene things. When I was a daily resident in the scif, I didn’t buy an apple watch because I’d not be able to wear it for about half my waking hours… It would be a liability that I’d forget one day and they’d confiscate it.
While I tend to see common rules, the security management for each facility often have their idiosyncrasies. What wasn’t allowed somewhere else will be allowed here & vice-versa. But best just to be prepared to have to leave electronics outside. You never know when you’ll be asked to travel or your facility will have an issue and you have to relocate, and the new place has different rules.
I guess I’d have a conversation with the facility security officer to come to some understanding.
