5.2. Surety paging relay of module RSAP-F2
Switches on activation of the priority input contact (by connecting pin 6 to pin 8 of the RJ45 INPUT connector). It is used to activate
external elements that must act at the same time as the speech preference. This allows, in installations with volume attenuators
and 3- or 4-wire loudspeaker lines, to ensure that messages with priority are broadcast regardless of the position of the volume
selector of the attenuator. Figure 14 shows an example of AV series attenuators connection with surety paging (3-wire speaker
lines) and figure 15 with CV series attenuators (4-wire speaker lines).
