Auxiliary Siren SW |
(DEK, DEK VIP) |
This feature provides an input for an auxiliary siren On / Off switch for the Siren option.
|
Since VIP (Vehicular Interface Port) Inputs are active-low, the auxiliary switch must ground the selected VIP Input to activate the Siren, and idle high to deactivate the Siren. When the DEK or Control Head reports the VIP Input state change (active or inactive) the transceiver sends an SB9600 bus message to the Siren / PA unit to change the Siren state On or Off. |
