Addressable Loop Expander for PFC-8500
The ALE-127 is microprocessor based circuit assembly that provides an additional signaling line circuit (SLC) to the Potter PFC-8500. The SLC is power limited and supervised. The PFC-8500 will supoort a total of three ALE-127 loop expanders. The ALE-127 is mounted above the main board assembly inside the cabinet. A wire harness connects the first ALE-127 to the main board and subsequent ALE- 127(s) are connected to the first.
The ALE-127 is configurable for Class A, Styles 6 & 7 or Class B, Style 4. The ALE-127 only operates with the PFC-8500 and utilizes the Potter/Nohmi line of sensors and modules.
