Off-Hook Relays
In a telephone based paging system, a telephone situated near a paging speaker can create acoustic feedback that makes paging impossible. Off-Hook Relays automatically disable paging speakers near the telephone to eliminate this problem.
Off-Hook Relays can also trigger signaling devices when, for example, an emergency phone is in use.
Guardian Telecom Telephone Enclosures & Accessories are designed with the versatility to enhance or replace components or workings.
