Simplex 4905-9815 — SmartSync Adapter Module for non-addressable notification appliance circuits.SmartSync appliances take separate horn and strobe commands over one two-wire NAC. This adapter breaks that signal apart into a conventional 24 VDC audible output and a conventional 24 VDC visible output, both still driven by the SmartSync source, so weatherproof appliances, bells or chimes can be used without losing separate audible and visible control. Input 16 to 33 VDC; 100 µA supervisory, 450 mA maximum in alarm Output 17 to 32 VDC, inrush limited to 550 mA, self-resetting overcurrent protection Regulated ratings 30 mA audible and 180 mA visible; Special Application 50 mA and 250 mA Up to two adapters per SmartSync NAC, appliances up to 200 ft away Reverse polarity supervision, two 10 kΩ, 1/2 W end-of-line resistors Mounts in a 4 11/16 in. square box; UL listed to Standard 864 A cover plate is required, ordered separately: 4905-9817 surface or 4905-9818 flush mount. Do not confuse this with the 4905-9938 SmartSync Control Module, which generates SmartSync control rather than decoding it.
