Model PD141

4 Point Annunciator with First-out

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.

Specifications

• NUMBER OF INPUTS: 4 per VIGILANTE; 8 per system.
  
• TYPE OF INPUTS Momentary or Maintained:
  
  • NO or NC switches: Each input circuit contains a pull-up resistor, so it is not necessary to provide external excitation to the switch.
    
  • Open Collector Transistor: Open circuit voltage is approximately 5 VDC.
    
  • Logic Levels: LO = 0 to .8 VDC, HI = 4.7 to 28 VDC; input impedance 100Kohms
    
• OUTPUTS: Alarm condition indicated in 3 ways:
  1. 1. Relay: 1 SPDT relay ( 2 A @ 240 VAC )
     
  2. 2. Audible: Built-in horn, 75dB.
     
  3. 3. Visual: Red LED next to the alarm message.
