Sensor Modules
Sensor modules available for a wide range of gases;
Combustible Gas* Sulfur Dioxide
Oxygen* Nitrogen Dioxide
Hydrogen Sulfide* Hydrogen Chloride
Carbon Monoxide* Hydrogen Cyanide
Chlorine* Ammonia*
Hydrogen Nitric Oxide
Hydrogen Fluoride Methane / Propane
* Refer to IT Series Data Sheet
Analog Input
The analog input modules, 5100-90 and 5100-99 enable the
user to use any sensing device that produces a 4-20 mA DC
signal to communicate with Sentry through an Analog/Digital
signal converter.
Output Expansion Module
The output expansion module provides the same capacity as
the individual Relay Panel, plus it provides 4-20 mA DC out-
puts proportional to the concentration for each sensor mod-
ule.
Software Enhancement Package
The Software Enhancement Package provides the Sentry sys-
tem with powerful software features by selecting from a menu
of factory set options. These features include:
• MODBUS protocol
Provides the MODBUS protocol software to interface with
a wide variety of third party software. (Other protocols
avalibale)
• Factory Edit Gas Tags and Module Tag
The tags normally selected by the user can be built-in
as default tags
• Enhanced alarm acknowledgment features
Provides high and low alarm acknowledgement and an
emergency alarm (third alarm) feature
Calibration Systems
Calibration gas can be delivered from a central panel through
permanently installed tubing to the sensors. Since Sentry’s
calibration adjustment is performed in software, it is not nec-
essary to make mechanical adjustments at the sensor. Alter-
natively individual gas delivery lines can be located near the
sensors.

Options to Expand System Flexibility
Battery Back-Up
The battery back-up system provides operating power when
AC power drops below 90 VAC. Includes battery, AC line filter,
two battery charging modes, and a 12 to 24 VDC converter.
History Report – lists the last time each significant event
has occurred. Includes
system power interrup-
tion, history reset, alarm,
concentration and cali-
bration information for
each sensor module.
Calibration Report – prints automatically when calibra-
tion is completed.
Diagnostic Report – lists the critical voltage conditions
for each module and can
be selected to print peri-
odically.
Relay Logic for Customized Response
Standard Relays- t he controller has DPDT dry contact
relays for low alarm, high alarm, and trouble. Any one sensor
can activate the appropriate relay.
Individual Relays – I f separate relay action is required for
each sensor, then the individual relay option is appropriate.
This option provides individual SPDT dry contact relays for
each alarm level for all sensor modules.
Custom Configuration Relays – the custom configu-
ration relay option permits decision logic before actuating the
relays. Any group of sensors in the same vicinity can actuate
the relay designated for that vicinity (zone).
