DVP-120M   
1,444.88

The DVP-120M is a Modbus-Enabled Detection and Ventilation Panel with up to 87 Modbus addressable sensors on three channels of 29 sensors per channel, plus the original 12 analog 4-20mA sensor channels. The DVP-120M increases the capacity of the DVP-120 from 12 detectors to 99. System wiring includes 4-20mA current loop and RS-485 serial interface.

When the DVP-120M is in alarm the internal buzzer will sound, the alarm lamp will be red and the LCD will show the sensor type and channel number. The DVP-120M has an externally visible LCD display showing the status of each transducer and relay. You can navigate this display by entering the channel # or scrolling through the channels with the key pad.

• External keypad for selection of the transducer/alarm display and configuration
• Externally visible LCD display showing the status of each transducer and relay
• Externally visible system, alarm and relay status indicators
• Compatible with all Macurco 6-Series and 12-Series gas sensors
• Twelve analog (current loop) input channels
• Three 10A, 240 VAC SPDT fan/alarm relays
• Drivers for external Horn and Strobe
• Fail-safe operation can be implemented
• Lockable NEMA 1 type enclosure
• Modular input and output connectors
• ETL Listed to UL 508A, CAN/CSA-C22.2 No. 14-13, LADBS Approved
• Up to three ventilation control zones can be defined
• Each zone can be controlled based on transducer signals and/or time of day
• Each relay is configurable for delay before activation and minimum on tim
• 12 analog (4-20mA) input channels.
• 87 addressable sensors on three channels of 29 sensors per channel
• External power supply is required for addressable sensors

Parking garages, loading docks, vehicle repair facilities, arenas, warehouses and other commercial applications

System wiring includes main power connection for the DVP-120M, 4-20mA current loop, RS-485 serial interface and 24VDC power connections between the remote detectors and the DVP-120M and the fan control and alarm connections from the DVP-120M to the building ventilation and automation systems. The DVP-120M control panel has three relays which can be used for ventilation fan control or alarm signaling. The ventilation control function operates independently from the alarm function. It provides the ability to configure the DVP-120M for control of one to three zones. Each zone can respond to gas levels at one or more of the sensors, with configurable rising and falling concentrations for each gas type. Each zone can also be controlled based on the time of day.

The Macurco MRS-485 adapter is an accessory used to convert the 4-20mA analog signal from Macurco 6-Series type detectors to a digital signal for use with multipoint addressable systems. The Macurco MRS-485 simply plugs into the back of the detector and a single screw fastens it in place. The MRS-485 accepts the 4-20mA output and is powered from the same connection as the detector. The MRS-485 has the ability to interface with the Macurco DVP-120M Modbus Enabled Detection and Ventilation Control Panel as well as Building Automation Systems or other control devices that accept Modbus communications.
