Commitment
Our quality and service are uncompromising. We back each of our products with a two-year warranty on all
materials and workmanship. We offer technical support, user training and on-site service and maintenance
of equipment to meet the needs of our customers.
Gas Detection Service
Individually designed maintenance packages are available for specific customer needs. Service begins with
verification of the system installation that includes an initial system check and calibration. We then offer
customer training programs (on-site and at factory) to insure that technical personnel fully understand
operation and maintenance procedures. When on-the-spot assistance is required, service representatives
are available to handle any questions or problems immediately.
Warranty
Sensor Electronics Corporation (SEC) warrants products manufactured by SEC to be free from defects in
workmanship and materials for a period of two (2) years from date of shipment from the factory. Any parts
returned freight pre-paid to the factory and found defective within the warranty would be repaired or
replaced, at SEC's option. SEC will return repaired or replaced equipment pre-paid lowest cost freight.
This warranty does not apply to items, which by their nature are subject to deterioration or consumption in
normal service. Such items may include:
Fuses and Batteries.
Warranty is voided by abuse including rough handling, mechanical damage, alteration or repair. This

II. GENERAL DESCRIPTION
CONVENTIONS
The following conventions are used in this manual.
Warning Statement
VDC (DC Voltage)
SEC 3500 HMI
The SEC3500 HMI Operator Interface, an Attendant-Monitored system, continuously interrogates
up to 254 system devices over the 9600 baud RS485 Modbus Interface. The OI, operating as the
Modbus Master, can communicate with any SEC3XXX Device and any 4-20 transmitter via the
SEC3100AIM.
There is a power indicator LED located on the front panel of the 3500.
Network devices can be interrogated, configured, and calibrated using the password protected
touchscreen user interface.
16 embedded programmable relays provide external device control/interface based on network
events. Additional relays can be located anywhere on the network (groups of 8).
The Statcast RS232 interface continuously scrolls through system operating status. (Read only
for the user)
An Ethernet port allows remote access to system screens.
The SEC3500 HMI refers to the system as a whole, not just the SEC3500 (what is inside the metal
enclosure).
WARNING: SUBSTITUTION OF COMPONENTS MAY IMPAIR SAFETY

III. OPERATION
The SEC3500 HMI Operator Interface is an intuitive operator interface. For the individual page
operations please refer to the following individual instruction manuals on the SEC website:
3500 OI Basic Operators Guide.pdf
3500 OI Startup Basics Guide.pdf

IV. INSTALLATION
1. Mounting Instructions:
a. Find an accessible spot for the SEC 3500 to be mounted. This spot
should have enough room for incoming/outgoing wires to be easily
routed around. The SEC 3500 should be accessible at a regular height
so the monitor can be easily accessed at all time alarms. Make sure the
monitor is in a safe location in case of alarm.
b. The SEC 3500 needs to be mounted on a solid wall
c. Recommended Hardware:
i. Use all 4 mounting brackets when mounting the SEC 3500
ii. Bolts: minimum of ¼” – 20 thread, 1 ½” long
iii. Nuts: ¼” – 20 Thread ½” Wide
iv. Washers: Minimum 0.260” ID, 0.750” OD for washers between
the bolt head and the SEC 3500. Maximum 0.375” ID, Minimum
1.50” OD for washers between mounting wall and bolt
2. The SEC 3500 requires an 18-29V DC power supply. This power supply must
cover Class 2 requirements as well as be UL 1310 approved. Then run the
power through the bottom-left hole of the SEC 3500 unit. Then connect the
power supply to the DC-to-DC converter.
3. Run the RS485 (Data Highway) through the bottom-left side hole of the SEC
3500. Then attach to the data highway to the proper terminals on the terminal
block.
4. When connecting 120 VAC (Class 1) circuits to the SEC 3500, wires should be
routed through the top-right opening. Then all class 2 and 3 power circuits going
to the relay switches should go through the bottom-left opening. Class 1 wires
must be kept at least 1/4”inches away from class 2/3 circuits.
5. Relay controller labeled 253 in the SEC3500 HMI housing has relay 1
designated for the alarm horn.
a. The horn needs to be supplied with +24VDC.
6. Sensor Electronics recommends not connecting earth ground and DC common
together. Instead connect earth ground to the bolt inside the enclosure. It is
located inside the enclosure on the bottom left and is connected to the panel
door.
7. For the UL2017 approval, all wiring that interconnects equipment must be
located within the same room.

Operation
The SEC 3100 ISO RS-485 Repeater Module is used in conjunction with the SEC 3100 transmitters and
the SEC 3500 HMI Operator Interface or other MODBUS RS-485 data highway systems. The SEC 3100
ISO RS-485 Repeater Module is used to extend the distance of the RS-485 network and increase the
number of devices on the RS-485 network. The SEC 3100 ISO RS-485 Repeater Module provides 1500
volt isolation bidirectional data flow and transient suppression on the RS-485 data lines. An SEC 3100
ISO RS-485 Repeater Module should be installed for every 1000 feet of data highway cable or 32 network
devices. The SEC 3100 ISO RS-485 Repeater Module is powered by 24 VDC and wired in line with the
SEC RS-485 network devices. A typical wiring diagram is shown below:
