The model PD141AFO VIGILANTE® four-point annunciator with First-out gives operators a simple, clear, ear and eye catching annunciator that handles urgent alarms and routine status messages. It directly handles alarm outputs from meters, alarm relays, logic levels (5v-28v) and switches for temperature, pressure, flow, level and proximity parameters. Change of status is announced by LEDs, built-in pulsating horn and relay for remote indication. The PD141AFO can be field programmed for ISA Sequence A, to detect momentary or maintained alarms or ISA Sequence F2A (First-out) which detects momentary and maintained as well as which alarm occured first. The front panel is NEMA 4X rated. Two VIGILANTES® can be mounted together to give the VIGILANTE® eight alarm points. Alarm message labelling can be performed in the field or at the factory with laser-printed labels at no charge.
