Introduction
The ProtEX-MAX PD8-150 offers all the functionality of the Vigilante II PD150 as a fully FM, CSA, ATEX,
and IECEx approved explosion-proof product. It provides alarming and monitoring capabilities for all of
your level, pressure, flow, and other process switches. These explosion-proof alarm annunciators are
available in two models; the PD8-154 has four (4) inputs and the PD8-158 has eight (8) inputs. Each
model accepts inputs from relays, float switches, digital outputs, and many other discrete (on/off) devices.
They can be field programmed for all common ISA alarm sequences including first out indication and
provide alarm signaling through front panel LEDs and a built in audible horn. Additional audible devices
may be triggered through the use of relays. The silence, acknowledge, and reset functions can be
operated without opening the housing by using the built-in SafeTouch through-glass buttons. Custom
printed message labels can be included with your order at no additional charge.

Setup and Programming
Overview
There are no jumpers involved in the setup process of the annunciator. The sequence selector switch,
located on the rear of the internal electronics module above the signal connector must be set accordingly
for annunciator sequence desired.
Normally open or normally closed input setup, relay fail-safe, and additional sequence options are
programmed with the infrared through-glass SafeTouch buttons, or using the mechanical buttons when
uncovered. There is a slide switch located on the connector board. This is used to enable or disable
SafeTouch Buttons.
After power and signal connections have been completed and verified, and the sequence selector switch
has been set appropriately, apply power to the annunciator.
For a Quick Setup Guide go to page 4
SafeTouch Buttons
The ProtEX-MAX is equipped with four sensors that operate as through-glass buttons so that it can be
programmed and operated without removing the cover (and exposing the electronics) in a hazardous
area.
These buttons can be disabled for security by selecting DISABLE on the switch labeled NO-CONTACT
BUTTONS located on the connector board.
To actuate a button, press one finger to the glass directly over the marked button area. Then retract finger
more than three inches from the glass before pressing the next button. When the cover is removed, the
four mechanical buttons located next to the sensors are used. The sensors are disabled when a
mechanical button is pressed and will automatically be re-enabled after 60 seconds of inactivity.
The SafeTouch Buttons are designed to filter normal levels of ambient interference and to protect against
false triggering, however, it is recommended that the SafeTouch Buttons be disabled (slide switch to
LOCK) if there is an infrared interference source in line-of-sight to the display.
The SafeTouch Buttons are configured by default to duplicate the function of the front panel mechanical
pushbuttons associated with the integrated meter. The symbols by each SafeTouch button correspond to
a mechanical button as shown in the table on the next page.
SafeTouch Button Tips:
•To the extent possible, install the display facing away from sunlight, windows, reflective objects and
any sources of infrared interference.
• Keep the glass window clean.
• Tighten the cover securely.
• Use a password to prevent tampering.

Press and hold SILENCE and ACK for 5 seconds to perform a function test. This tests the sequence
operation and hardware by simulating alarm inputs that are cleared in the normal sequence progression.
During the function test, all channels enter a simulated alarm state for 3 seconds. All LEDs, pushbuttons,
relays, and the audible alarm will follow the selected sequence as if the simulated alarm inputs were real.
After 3 seconds, the alarms may be cleared as normal for the selected sequence.
Multiple Unit First-Out I ndic a t ion
If multiple Vigilante II annunciators are connected for multiple unit shared first-out indication (see page
17), only one input from all connected devices will display as a first-out alarm.
Each individual annunciator will acknowledge and reset the channels on that unit using the pushbuttons
on that unit, and independent of all other connected units. Only the unit displaying the first-out will sound
the audible alarm.
It is recommended that all connected units be set for the same first-out sequence.
To control all the units from any of the front panels, connect the SIL, ACK, RST, and COM terminals on
each unit.

Full Sequence Descriptions
The following section describes the operation of the various sequences available in the Vigilante® II alarm
annunciator.
Features
Acknowledge Pushbutton: Momentary alarms will not clear until the alarmed channels have been
acknowledged with the ACK pushbutton. This will also reset the first out indication. Used in all ISA
sequences.
Automatic Reset: Acknowledged momentary alarms will clear automatically when the inputs return to
normal. The automatic reset is present in all automatic (A) sequences.
First-Out Indication: The sequence provides a distinct visual indication for the first channel to alarm.
First-Out Reset Pushbutton: Resets the first-out display and assigns the first-out channel to display as a
subsequent alarm without any other changes to the sequence. The next alarm input will be a new first-out
alarm. Used only in sequence F3A.
Reset Pushbutton: Acknowledged momentary alarms will only clear when reset with the RESET
pushbutton. Used in any manual reset (M) sequence.
Sequence Condition Descriptions
The following terms are used in describing the sequence behavior in the following tables:
Alert: The input is in alarm state, and the channel has not been acknowledged with the ACK pushbutton.
Acknowledge: The alarm state is acknowledged with the ACK pushbutton. This will restart the first-out
indication.
First Out Reset (F3A Only): The RESET pushbutton is used to reset the first-out indication only.
Normal: Inputs are in the normal state.
LED Condition Descriptions
1st Pt: Indicates the behavior of the first-out channel only.
Next Pt: The behavior of subsequent alarm channels; channels that enter the alarm state after the first-
