摘要: The present disclosure provides an alarm call point which is able to discriminate between activation in an alarm situation and activation in a test situation (e.g. activation using a test key). This arrangement allows an alarm system to be tested without needing to put the control panel into a special test mode, making it easier and quicker to install, commission and test the system.

摘要: The present application provides an optical filter (3), and a test assembly and method for a smoke detector. The optical filter (3) comprises: a support (30); and a screen (31) supported by the support (30), wherein the screen (31) is composed of wires (32) and mesh holes (33) are defined between the wires (32), and the screen (31) has a first side and a second side opposite to each other; wherein, the smoke detector comprises a light transmitter (21) and a light receiver (22) arranged in vicinity and an light reflector (4) arranged opposite to the light transmitter (21) and the light receiver (22), such that light emitted by the light transmitter (21) is reflected to the light receiver (22) via the light reflector (4); and wherein, during testing, the optical filter (3) is arranged in both the light path (51) from the light transmitter (21) to the light reflector (4) and the light path (52) from the light reflector (4) to the light receiver (22), where at least the side of the wires (32) of the screen (31) facing the light transmitter (21) of the smoke detector is convex so as to attenuate or eliminate the light directly reflected back to the light receiver (22) by the optical filter (3). The device and method according to the embodiments of the present invention can accurately test a smoke detector.
