 DESCRIPTION
The Series 1700 is a fast-acting, fail safe detector of Chlorine or Sulfur Dioxide gas. It accurately covers the range 0-30 parts per million (ppm) of the gas in air. The 1700 Gas Detector is sensitive yet sturdy enough to operate reliably across a wide range of temperatures and humidity and in local and remote industrial applications, such as water and wastewater treatment plants.

The Series 1700 is a compact system that is weatherproof and includes an electrochemical Gas Sensor and a microprocessor-based Alarm Indicator Unit, both designed for wall mounting.
 
 FEATURES
Gas Sensor

The Series 1700 sensor is housed in a weatherproof enclosure with an LED to indicate that power supply is present. The sensor is stable and practically maintenance free. Its cell is designed to provide trouble free performance throughout its life and can be replaced easily. The sensor is a high resolution transducer that reacts quickly to changing levels of ambient gas, transmitting a proportional 4-20mA signal to the alarm indicator. A second point sensor may be provided as an option, for local or remote installations.

ALARM INDICATOR UNIT

On the Alarm Indicator panel, the gas type followed by its ppm value is shown at one second intervals on an eight digit LCD. Simultaneously, the gas level is indicated on an LED bar graph. Any alarm condition is signaled by an audible and visual alarm, and its source identified on the LCD display. The LCD also indicates whether the audible alarm is operative and facilitates the alarm setting procedure. A 12V battery, built into the Alarm Indicator, provides back-up power in case of main power supply failure.

ALARM SETTINGS

There are five alarm conditions : 1-Low, 2-High, 3-Critical, (all three of which may be selectable between 0.1-29.9ppm), 4-Sensor Failure Alarm, 5-Power Supply Failure. The Alarm set-up is achieved simply via the Alarm Indicator’s keyboard and stored in the EEPROM memory. The memory is secure until overwritten regardless of main power or battery power status. To test or clear alarms there is a simple verify and cancel procedure.
