Instruction Manual 1. PRODUCT DESCRIPTION 1.1 Introduction All versions of the Model 3100 Flame Detector Series utilize Ultraviolet, Infrared and Visible spectrum to provide continuous and reliable flame detection. The microprocessor in the Model 3100 is configured with state-of-the-art fire algorithms and continuously analyzes the data from the sensor array for individual intensity values, change of intensity values, relationship of intensity values and frequency signature correlations.
Instruction Manual 2. OPERATION 2.1 General When the Model 3100 Flame Detector is powered up, the microprocessor checks the configuration switch settings and configures the detector. The microprocessor then runs a full series of self tests. After the self test process is complete and all tests are passed, the detector is ready to detect a fire. All modes of operation are indicated by two LEDs located on the front of the detector. Normal Mode is indicated by a brief flash of the LEDs every 8 seconds.
Instruction Manual SW1 SW2 SW3 SW4 SW5 SW1 Shown in off position SW2 Shown in on position SW9 SW8 SW7 SW6 Figure 2-2: Configuration Switches 2.2 Field-of-View (See Figure 2-1) Optical Flame Detectors must be able to “see” the fire to declare an alarm. Any obstruction between the detector and the threat area will impair the detectors ability to cover the threat area. An obstruction is anything that is not transparent to the sensor elements of the detector.

The Verify Control switches allow the user to select the verify level, disable the verify function, or make the Verify Relay operate in parallel with the Fire Relay. The verify function in enabled when the detector declares an alarm.
Instruction Manual Figure 2-4: Model 3100 Series Detector Module (Back) (“on” or “off”) of a switch (SW1-SW8). The first flash pattern indicates the position of the first switch (SW1), with each consecutive flash indicating the position of the next switch in order. The flash pattern is as follows: only one LED “on” indicates a switch in the “off” position, both LEDs “on” indicates a switch in the “on” position. The position of SW9 is not indicated.
Instruction Manual ing” - remain energized until power is removed, ”Fire Following” - de-energize a short time after the fire is no longer detected. The “J2” connector provides connections for both normally open contacts and normally closed contacts on the Fire Relay. 2.7.2 Fault Relay The Fault Relay is a normally energized relay. It will de-energize when a Fault occurs.
Instruction Manual 3.0 INSTALLATION 3.1 General Precautions All wiring and installation must be done in accordance with the NFPA 70 and 72 standards and must comply with any codes specific to the application or location. Contact the local authority having jurisdiction and the company safety engineer for information on codes which may apply. 3.2 Housing and Conduit 3.2.1 Mounting the Housing The housing is mounted by using the two 0.3” diameter holes located in ears on the back of the housing.
Instruction Manual 3.3.5 Auxiliary Relay The Auxiliary Relay connector is located between the Power and Fire Relay connectors. The connection points are labeled “Aux In” and “Aux Out”. The Aux. Relay is configured for Normally Open (3100-03 and 310004), or Normally Closed (3100-02 and 310005) operation at the factory. 4.0 MAINTENANCE The self-test functions eliminate the need for most regular maintenance procedures.
Instruction Manual 5.0 TROUBLESHOOTING The flame detector has several built-in self test mechanisms which verify function and calibration. The following procedure covers most faults and problems which may occur during installation or during the course of normal operation. 5.1 No LED blink or erratic LED blink With power connected to the detector the LEDs on the front of the detector module should begin blinking and blink about every 8 seconds. If they do not blink or blink in an abnormal fashion. 1.
Instruction Manual 1. If the relay closes (0 ohms on the meter) and the LEDs come “on” the detector is operating normally. Check external alarm initiating circuit wiring. 2. If the relay closes and the LEDs remain off, or the relay remains open and the LEDs come on, the detector needs factory service. 3. If the relay remains open and the LEDs remain off, contact the factory for further diagnostic information.
