Description

The Series 1700 is a fast-acting, fail-safe detector for Chlorine and/or Sulfur Dioxide gas. It accurately covers the range of 0-30 parts per million (PPM) of the gas in air. The 1700 Gas Detector has up to two independent gas sensors that will monitor the environmental condition in two separate rooms.

Features

Gas Sensor: Each Series 1700 Sensor is housed in a weatherproof enclosure with an LED to indicate that power is being supplied to the sensor. Each sensor is stable and practically maintenance free. Its cell is designed to provide trouble-free performance throughout its life and can be replaced easily. Each sensor is a high-resolution transducer that reacts quickly to the changing levels of ambient gas, proportional to the level of the specific gas to the Alarm Indicating Unit.

Alarm Indicating Unit: The Alarm Indicating Unit has a backlit LCD display with two lines of 16 alphanumeric characters in each line. The unit provides an isolated 4-20mA output signal for recording or transmission to a remote instrument or computer. RS232 and RS485 digital signals are also available.

Any alarm condition is signaled by an audible alarm and is indicated on the LCD display. A danger alarm from either sensor will be displayed on the corresponding LED alarm light.

Three programmable alarm relays are provided: two for actuation of Danger and Critical alarm levels; the third monitors sensor failure and, when furnished, backup battery condition. Alarm set points and configuration parameters are programmed directly through the front panel pushbuttons and stored in non-volatile EEPROM memory. Battery backup is optionally available.

The Series 1700 is a compact system that includes one or two electrochemical Gas Sensors and a microprocessor-based Alarm Indicator Unit, all designed for wall mounting.

Calibration

Field calibration of the 1700 is simple. A special program feature in the indicator allows the operator to perform field calibration from the keypad using only a simple voltmeter and a 4-20 mAdc signal generator. Whether calibrating electrically or using a calibration gas, there is no need to open the instrument to accomplish calibration.
