ABSTRACT:
Alarm system includes a controller, a single-wire loop connected to the controller, identification modules connected to the single-wire loop and attachments to or incorporated structures on or in the identification modules. Attachments or incorporated structures include digital and analog devices. Each identification module is programmed to provide a signal or report to the controller indicative of whether the associated device is in a normal state or in an alarm/trouble state. When analog devices are used, the identification modules may be designed not only to convert the analog readings to digital form but also to provide for a permitted range of variation in the sensor readings so that not all variations from a single, predetermined value of the condition being monitored by the sensor are considered indicative of a problem with the area being monitored by the sensor or a fault with the sensor.
