Precision digital vigilante annunciator PD141AFO-3
The Annunciator can be set up without removing it from its case and involves two choices.
1. ISA Sequence A or ISA Sequence F2A
2. Alarm designated by a high (or open) input or by a low (or closed) input.
A switch located next to the screw terminals at the rear of the instrument is used to select the sequence under which the Annunciator will operate. Slide this switch toward the rear of the instrument (marked A on the PCB) forISA Sequence A operation.
Alarm on a contact opening or closing is determined for each channel by a switch located beside the message LED for the channel.
When a switch is in the forward position, that channel will alarm when the input contact is opened. When a switch is in the rear position, that channel will alarm when the input contact is closed.
Access to these switches is gained by removing the Annunciator cover. The Annunciator cover is held in place by 6 latches that snap into notches on the snap-off cover. To remove the snap-off cover from the Annunciator, grasp it firmly on its short sides and pull it forward. The latch plate remains around the Annunciator case.
Annunciator Signal & Power Connections
The VIGILANTE® can be field programmed for either ISA Sequence A or ISA Sequence F2A.
Connecting Two Annunciators Together
Two Annunciators may be connected together to form an 8 input system. If the Annunciators are programmed for ISA Sequence F2A, they will detect which of 8 inputs was first to alarm. The Acknowledgement switches will be wired together, so either one can be used to acknowledge an alarm. However, each Annunciator relay will operate independently, so it may be necessary to wire them in parallel to drive a single alarm device. Each Annunciator horn also operates independently.
Two Annunciators Connection Pattern
Annunciator Mounting Dimensions
A: 4.83†(123 mm) required for installation
1. Panel cutout required- 3.622†x 1.772â€
2. Panel thickness- .125â€-.250†(3.17 mm-6.34 mm)
3. Clearance: allow 6 inches (152 mm) behind panel
Alarm message labels for the Annunciator may be factory printed at no charge, or field printed using a laser printer with clear self-adhesive labels.
Factory printed message labels may be ordered at any time by completing the form on the back of the instruction manual. (Note: message #1 is the top message.)
Area available per message is 1.25"x .5" (32 mm x 12.7 mm); user may specify any size and length that will fit in this area. Two lines of 14 characters each at 9 point type will fit.
Except where noted all specifications apply to operation at +25°C.
NUMBER OF INPUTS: 4 per VIGILANTE®; 8 per system
TYPE OF INPUTS: Momentary or maintained:
1. NO or NC switches: Each input circuit contains a pull-up resistor, so it is not necessary to provide external excitation to the switch.
2. Open Collector Transistor: Open circuit voltage is approximately 5 VDC.
3. Logic Levels: LO = 0 to .8 VDC, HI = 4.7 to 28 VDC;input impedance: 100 KΩ
OPERATION: User field select: ISA Sequence A or ISA Sequence F2A (first-out).
TYPE OF OUTPUTS: Alarm condition indicated in three ways:
1. Relay: 1 SPDT relay (2 A@ 240 VAC) per PD141AFO.
For fail-safe design, the relay is energized in the non-alarm state. In the case of a power failure, the relay will go to the alarm state (NC contact is connected to Common contact).
3. Visual: Red LED next to the alarm message.
ALARM MESSAGES: Custom printed free of charge. Area available per message is 1.25"x .28" (32 mm x 7 mm); user may specify any size and length that will fit in this area. Two lines of 14 characters each at 9 point type will fit.
AC: 115 VAC ±10%, 50/60 Hz, 3 VA.
230 VAC ± 10%, 50/60 Hz, 3 VA.
DC: 24-48 VDC, 2 W max., 500 VDC isolation.
CONNECTIONS: Removable screw terminal block.
ENCLOSURE: 1/8 DIN, high impact plastic, UL 94V-0, color: black.
FRONT PANEL: NEMA 4X, panel gasket provided.
Operating temperature range: -20 to 70°C.
Storage temperature range: -40 to 85°C.
Relative humidity: 0 to 90% non-condensing.
WARRANTY: 1 year parts and labor.
EXTENDED WARRANTY: 1 or 2 years
