2. Characteristics, Scope, and Specs

QTY PART # DESCRIPTION

1 Controller Enclosure: Powder coated aluminum Communication: Modbus TCP & RTU (RS485) User Interface: 5” Touch Display Data Storage: 8GB Power input: 5VDC Via plug-in adapter (provided) Alarm: Sound and email alarms AccuSafe can host up to ten sensor modules reporting to a single controller

5 AS18-2.00m Principle of Operation: Electrochemical Hydrazine sensor (AN181700) CIH Adj. +50 mV bias Measuring Range: 0-2.00 ppm Accuracy: +2% of reading +1 least significant digit Integral sample Pump Enclosure: Powder coated aluminum, rated IP68 Communication: Modbus RTU OR TCP, slave-only

(PLEASE SPECIFY)

Power input: 12VDC via plug-in adapter (provided) Particulate filter

3 AS15-10.0m Principle of Operation: Electrochemical N2O4 (NO2/C-

1) CIH, Fixed 0 bias Measuring Range: 0-10.0 ppm Accuracy: +2% of reading +1 least significant digit Integral sample Pump Enclosure: Powder coated aluminum, rated to IP68 Communication: Modbus RTU OR TCP, slave-only

(PLEASE SPECIFY)

Power input: 12VDC via plug-in adapter (provided) Particulate Filter

1 DAT9550/DAT3138 Remote Display and relay contacts for remote alarms

3 040-00098 Local alarms: Audible and Visual alarms attached to junction box mounting at each sample location visual alarm is activated by user adjustable low alarm level.

Audible alarm is activated in rooms with two gases if either gas exceeds alarm level.

Communication from controller to remote display and relays is typically RTU. TCP is available with additional hardware and costs.

Above system must be used in general-purpose are only. The above items are not rated for class 1 division II areas.
