The Q4C is a multi-channel controller display and alarm unit that utilizes digital communications to interface with a maximum of four (4) remote digital transmitter/sensors. This series provides reliable measurement of a wide variety of toxic gases such as CO, NO2, NH3, H2S, SO2, Refrigerants, and Combustibles. The RS-485 communication is connected via a 4-wire, multidrop daisy chain configuration to reduce the overall installation cost of the system. Alarm setpoints are set through the front keypad or through supplied software that is downloaded to the controller from a PC or laptop computer. Common relay configurations include voting, averaging, delay on actuation and de-actuation, normally or not-normally energized and latching. The audible alarm has three buzzer settings; continuous, intermittent and double-tap intermittent. The Q4C has a dedicated 24 VDC transistor output terminal for horn and strobe. Available options include; a four (4) SPDT relay board, an analog output board that features 4-20 mA or 2-10 VDC outputs assignable as averaging or peak mode, and an RS-485 output board to communicate with an M-CONTROLLER. The Q4C comes standard with a 2 x 8-character backlit display, key pad, software CD and interface cable. Refer to all applicable Federal, State, Provincial and Local Health and Safety laws and regulations before using these products.
