In addition to commands and status functions, the Auxiliary Control/Status Option has
transformer coupled circuits for accepting audio. One circuit is active in conjunction with
the Public Address command, while the other circuit is used for local audio, such as a local
microphone or paging system. The local audio must have a “Push To Talk” contact closure
for operation. In either case the audio is broadcast over the system.
To activate one of the supported commands, simply make a closure between the desired
command input and ground. Typically, a relay is used to make a remote connection. An
open collector device may be used, as long as it meets the electrical specifications of this
document.
When an input is activated by a momentary closure, the siren function will run for the pre
programmed time or until another command is activated. For example, the Cancel
command will override a warning tone and silence the siren. Note that if a closure is
maintained, it can not be overridden.
