2/6

DescriptionDetcon Model Series 12 gas detection and alarm systems consist of single sensor control cards that can

be integrated into one system design to create multi-function monitoring and control of a wide range of fielddevices. Field devices include gas detection sensors, flame and fire detection devices and process sensors. Eachcontrol card is capable of supervising a single field device, displaying the current status of that device andproviding alarm relay outputs once user-configured limits are detected. Gas detection control modules displaythe real time concentration of a wide range of toxic gases, combustible gas, and oxygen sensors that output a4-20 milliamp signal. The flame detection module displays the real time status of any flame detector with a 4-20 milliamp output signal. The alarm annunciator module can be used to monitor smoke and thermal detectors,pull stations, and dry contact closure devices.

Model Series 12 single sensor control cards feature four alarm relays. Three relays are used as active alarm controloutputs and the fourth relay is a fault condition relay. Each alarm relay is adjustable in single digit increments

across the range of sensitivity. Alarm relays can be user-configured as latching, non-latching, normally energizedor normally de-energized via simple onboard programming jumpers. Front panel indicators include alarm statusLEDs and a 7-segment LED digital display of the real time concentration of a field device when applicable. Eachmodule is addressable via RS-485 serial communication.

Detcon manufactures a variety of pre-engineered Model 12 Series mainframe hardware assemblies includingNEMA 1 panel mount, standard 19 rack mount, NEMA 4X weather-proof and NEMA 7 explosion-proof.Engineering services for high density integrated fire, gas and process control systems are available from the factory.

Remote Display Capabilities

Model 12 Series control systems integrate directly with hardwire 4-20 mA inputs from field devices. All modelsoffer discrete relay outputs for each sensor and provide the ability for relays to be set up as zoned or common. TheRS-485 serial output can be connected to any DCS, PLC or SCADA host control device. The RS-485 serial outputis also used to drive optional remote Read-Only Displays. Typical integration configurations are shown below.
