SafeGuard Alarm Controller
16-channel Modbus® Safety System Display and Control
The SafeGuard Alarm Controller is designed as a
cost-effective mini-system controller alternative
to expensive PLC systems. The SafeGuard comes
standard with a centralized, easy-to-read LCD
providing simultaneous status on 16 channel inputs
as well as several expansion options including Mimic
Display capabilities and HMI software packages.
The SafeGuard can be equipped for any application,
indoors or out, with your choice of a basic wallmount,
a weather-proof fiberglass enclosure or rack panel
mounting.
8-channel display mode and boards allow for
economical conguration for smaller systems
Dual Modbus® RS-485 serial ports for
simultaneous master/slave operation
Alarm zoning feature available - monitor specic
zones at the same time or entire areas
Relay acknowledge feature allows silencing of
external audible devices during alarm
Graphic LCD readout displays monitored data as
trends, bar graphs and engineering units
Standard A SPDT common alarm relays for
HORN, HIGH, WARN and FAULT. Optional discrete
channel alarm relays also available
Alarm event printer interface
Cal mode offers push button zero/span
calibration
Authorization mode allows locking of critical
conguration variables
Magnetic keypad available for nonintrusive
operation in potentially hazardous locations
NEMA 4X Enclosure wallmounts, basic wallmount
and rackmount options available

Features and Benefits
The SafeGuard Controller is easy to congure and user friendly
Measurement ranges in engineering units, adjustable alarm
set-points, dual serial interfaces and many other features
combine to allow the SafeGuard to satisfy the needs of many
demanding applications. It is widely used for centralizing the
display and alarm processing functions in critical ame and
gas detection applications.
An RS-485 Modbus
be multidropped onto a single data highway for interrogation
by another Modbus master. SafeGuard’s may also be cascaded
by connecting one unit’s master port to another’s slave port.
®
slave port allows up to 128 SafeGuard‘s to
SafeGuard options such as discrete alarm relays per channel
or 4–20 mA I/O are added by connecting appropriate 8 channel
boards (2 required for more than 8 channels) to the economical
I2 C expansion bus. Familiar “telephone style” cables and
connectors interface to this bus. Versatile, expandable, and
a wide range of system conguration options – satisfying the
most demanding user applications.
