1.0 OVERVIEW
Model PT2008 is a Remote Annunciator and Data Logger for alarm and data display of
PT900 series Gas Monitor & Controller System. The annunciator/Data Logger is factory
programmed to operate in either of two modes:
Slave Mode: In this mode the data is transmitted to the annunciator by a remote
transmitter model PT710. In this mode PT710 Transmitter sends the data for all the
control modules in the main control panel. In the slave mode multiple remote annunciator
can be connected over single RS485 Network.
Master Mode: In this mode the annunciator collects the data from all the control modules
in the main control panel. Only one annuciator can be connected on single RS485
Network.
For establishing communication link between the PT750 Annunciator and the PT900 Series
Gas Monitor:
Refer to Figure 3 if your application requires the use of only one annunciator with
the main control panel
Refer to Drawing B2012124 at the end of the document if multiple Annunciators are
used with Model PT710 Remote transmitter.
For RS485 communication link always use twisted shielded data cable. The maximum
length of the cable without the use of repeater is 4000 feet.
1.1DATA DISPLAY
PT2008 Controller displays sensor location tags ( or default channel numbers) and the
sensor readings. For controller programmed for more than 8 channels, data is displayed
eight channels at a time. Each screen displays data for 15 seconds and then display is
switched for next 8 channels and so on.
1.2FRONT PANEL
On the front panel are visual alarm indicators and keypad switches to program controller
configuration. Also, the RESET and ACK key switches are used to Reset and
acknowledge any active alarms on PT900 main control panel.

PT2008 Remote Annunciator & Data Logger Rev 2.0 Page 6
1.3KEYPAD SWITCHES
RESET: When pressed it will Reset any currently active alarms on PT900 Main Control
Panel
ACK: Pressing the key will bypass active alarms on PT900 Main Control Panel for 30
minutes. The Bypass message is sent the control module in main control panel.
After 30 minutes if any sensor is still in alarm state the alarm relays will be
activated again.

2.2 AC POWER INPUT
Refer to figure 3. Connect 110/220 VAC power to the Din-Terminals. If only 24VDC
power is available simply disconnects DC out wires from the AC/DC Power supply and
connect external DC to RED and BLACK terminals next to power supply module.
2.3 CONNECTING RS485 DATA CABLE
RS485 link is used to communicate between the PT900 Series Control Monitors or PT710
Data Transmitter and PT2008 annunciator. If PT2008 Annunciator is operating in a slave
mode then PT710 Remote transmitter must be used to connect establish communication
between PT900 Control Panel and the annunciator. In the mode multiple Annunciator can
be used on a single RS485 network. However, if PT2008 is to run in Master Mode than
only one Annunciator can be used and must be connected directly to RS485 connector on
PT900 Control panel. Thus PT710 data transmitter is not used.
A two (2) conductor shielded cable (data quality type) must be used to avoid noise
transmission. Maximum of 4000 feet cable can be used for data link. Connect the
shielding wire of the cable to the terminal “Shield Gnd” or connect to external field ground
if available.
The RS485 terminal is simply connected to the RS485 terminal on the PT710 Remote
transmitter. Be sure to connect each pole of the terminal with right polarity.

WARNING
Do not run the RS485 cable close to high power lines or areas with high magnetic field.
High power lines induce noise into the data cable which may distort the communication
between the monitor and the annunciator.
2.4START UP
Complete the following procedure for the normal operation.
1. Complete the wiring and mounting of the enclosure described in earlier section.
2. Verify all the wiring connections to be correct and secure.
3. Connect the shielding wire of the communication cable to Field ground.
2.5APPLY POWER
Apply the power to the unit. Upon power up the LCD will display the startup message of
the unit model number and current software revision.
After 5 to 8 seconds the unit will return to normal operation by collecting data from the
control modules on PT900 Series gas monitor.
2.6INITIAL UNIT SETUP
Refer section on Unit Configuration to change factory defaults and modify initial settings.
Verify Date and Time are correct
Verify Number of Active Control Modules on PT900 Series Control panel is same as
active channel count. Default is 12 channels.
Modify Sensor Location tags if necessary

PT2008 Remote Annunciator & Data Logger Rev 2.0 Page 11
2.7 NORMAL OPERATION
The annunciator continuously collects data from the Gas Monitor via RS485 serial
communication and displays the gas readings and currently active alarms, if any.
Figure 4 below is an example of the data displayed by the annunciator. Remember that
the sensor tag or location names in the left column of the LC display are programmable.
Programming Sensor location tags are discussed later in this manual.
In normal mode the unit displays data in a cycle. Eight (8) channel data is display at a
time. Each data screen is active for 15 seconds before the screen is switched to next 8
channels. If any time in normal mode an ENTER key on the front panel is pressed the
display will skip to next screen. This feature is useful when the user quickly wants to
view the channel data which not currently being displayed.
Each line on the LCD displays:
Sensor tag or location
Sensor type, H2S, LEL , SO2, O2, etc.
Current gas reading. If the sensor is in alarm bypass, Calibrate or Sensor malfunction
mode then the appropriate message is displayed instead of the sensor gas reading.
If any of the sensors is in alarm state then unit displays the “ALARM SCREEN “. In
this screen only the sensors that are in alarm state are display.

2.8 DATA COMMUNICATION
The annunciator continuously collects data from all control modules in PT900 series gas
monitors. Upon startup the annunciator tries to establish communication with the remote
transmitter . If there is no response from the transmitter an error message
“Communication Failure” is displayed on the LCD. Annunciator continuously tries to
establish communication. The Communication Fail message will disappear when the link
has been established.
If a control module is not communicating with the remote transmitter then the
annunciator will display dashes or N/A. To correct the problem do the following.
1. Remove the control module from the rack assembly for 3 to 5 seconds.
2. Reinsert the module making sure it snaps into the card edge connector behind the rack
on the termination board. Secure the module in the rack with captive screw on the
front panel.
3. Make sure the number flashing on the module display matches with the channel ID
number. This ID or address must be distinct for each control module. There should be
no two control modules have the same ID or channel number. If the control module
ID number is incorrect then program the address by first putting the toggle switch in
NORMAL position and then pressing the push button switch on the front panel of
PT900 control module. Once the display reads the correct address release the switch.
After 5 seconds the module will save the address in the memory and returns to normal
operation.
4. Wait about 10 seconds to establish communication with the module.

2.9 ALARMS
There are three (3) dry alarm relay contacts provided each rated at 5 Amps. Relay 1 and
Relay 3 are pre-wired at the factory to an internal buzzer for local audible alarm.
However, the buzzer can be disconnected and these relays can be used for External
Audible and visual Alarm Devices. Note that the relays are rated 5 AMPS and therefore
the power consumption of the Audio/Visual device must not exceed this rating.
Alarm relay 1 will be activated if any of the H2S control modules is in alarm state that is if
Low, High or Hi-Hi alarm is active. The alarm relay will deactivate when all the H2S
alarms are cleared on PT900 Series gas monitor.
Alarm relay 3 will be activated if any of the LEL control modules is in alarm state that is if
Low, High or Hi-Hi alarm is active. The alarm relay will deactivate when all the LEL
alarms are cleared on PT900 Series gas monitor.
FAULT Relay is activated if any control module have an active malfunction alarm.
Important Note:
The alarm relays on the annunciator will not be activated if the control module on the
PT900 Gas Monitor is in alarm bypass mode even when the module gas reading is above
alarm level.
2.10 ALARM RESET
The alarm relays can be deactivated by pressing the RESET key on the front panel of the
annunciator. Simply press and hold the switch until Alarm reset message is displayed on
the LCD. The annunciator will deactivate the local alarms and sends the RESET command
to all the control modules.
Thus pressing the RESET switch will deactivate all the alarms on the annunciator and
PT900 Series gas Monitor system.

PT2008 Remote Annunciator & Data Logger Rev 2.0 Page 14
2.11 ALARM BYPASS / ACKNOWLEDGE
When the “ACK(nowledge)” key on the front panel is pressed the unit will send an alarm
bypass command to all the control modules that are currently in alarm state to deactivate
the relays and set them in bypass mode for next 30 minutes. Thus the alarm will not be
activated by the control modules / sensors for 30 minutes. This feature allows the
personnel to monitor particular sensor(s) without alarm devices being active for 30
minutes. However, this command will not effect the modules that are not currently in
alarm state. The alarms can be activated by these sensors/ modules if the gas readings
exceeds alarm level.
