The 22051E-26 is a white Series 200 Advanced analogue addressable photoelectric (optical) smoke sensor without an isolator, supplied under the Morley-IAS brand and manufactured by System Sensor. It uses the Series 200 Advanced protocol and is mechanically and electrically backwards compatible with existing Series 200 Plus devices. It requires a B501AP base (sold separately).
