... The trip points for this alarm are also programmable. The device can have addresses (determined by 2 address pins), so there can the NE1617A on the SMBus. It can also be put in a standby mode (in order to save power). This can be done either with software (over the SMBus) or with hardware (using the STBY pin) ...

... A shielded twisted pair is recommended for a long distance remote sensor. Connect the shield of the cable at the device side to the NE1617A GND pin and leave the shield at the remote end unconnected to avoid ground loop. Also notice that the series resistance of the cable may introduce measurement error; 1 can introduce about 0 ...
