Adjustable fire protection assemblies and methods are provided. The assembly includes a sprinkler having a body with an outer encasing surface and a deflector supported from the body. An escutcheon having a receiver and a rim surround the fire protection sprinkler to define an aperture between the receiver and the sprinkler. A push-to-connect fitting of the assembly includes a tubular member with an end for connection to a pipe and an internal conduit that receives the sprinkler body. A seal member and a retaining ring are disposed within the tubular member to form an adjustable seal and grip about the sprinkler body. A releasing member translates to disengage the retaining ring from the sprinkler body; and the escutcheon translates with respect to the tubular member in a sliding surface engagement to define an adjustable deflector-to-rim distance between the rim of the escutcheon and the deflector of the sprinkler.

A device and method for facilitating convenient measurement of airflow in a duct detector. The device may include a detector assembly and an airflow sensor mounted within the detector assembly. The airflow sensor may be coupled to a remote control device, such as via control circuitry. A method for testing airflow in the duct detector may be performed by measuring airflow in the detector assembly, generating a signal that corresponds to the measured airflow in the detector assembly, and determining whether the generated signal exceeds a predetermined threshold signal level. If the generated signal does not exceed the threshold signal level, alarms may be activated and/or blowers in a ventilation system may be deactivated.

A self-testing notification appliance includes a notification emitter, a verification circuit, and a controller. The notification emitter is operable to output light or light and sound based on a control signal. The verification circuit includes a notification sensor to detect the light or light and sound and generate a verification signal. The controller sends the control signal to the notification emitter and receives information based on the verification signal from the verification circuit. The self-testing notification appliance may be part of a network including a fire control panel and a plurality of additional self-testing notification appliances. The self-testing notification appliances may be assigned addresses on the network.
