A secured method of controlling a smoke control system is described herein. One device includes a user interface configured to display a smoke control element that represents a component of a smoke control system of a facility, receive a password, and receive a selection of an action to be performed by the component of the smoke control system, a memory, and a processor configured to execute executable instructions stored in the memory to cause the action to be performed by the component of the smoke control system in response to verifying the password is valid.

A control mechanism includes an actuator having first and second positions, a resilient member arranged to bias the actuator toward the second position, and an input cable. The input cable is arranged along a serpentine path and is connected to the actuator, the input cable arranged to retain the actuator in the first position using tension applied by a plurality of detector cables along the serpentine path of the input cable. Fire detector connector modules, fire suppression systems, and methods of integrating detector cables into control mechanisms are also described.

A safety cabinet includes an enclosure and at least one door to selectively seal the enclosure. The safety cabinet can be used to store, for example, flammable liquids, flammable waste, corrosives, pesticides, or combustible waste. The safety cabinet incorporates a thermally-actuated damper that includes a body, a valve plate, and a pivot assembly. The valve plate is disposed within the passage of the body such that the valve plate is movable between an open position and a closed position. The pivot assembly includes a biasing system adapted to bias the valve plate to the closed position and a fusible link interconnected between the body and the biasing system to constrain the valve plate from moving from the open position to the closed position. The fusible link is configured to melt at a predetermined temperature to thereby allow the biasing system to move the valve plate to the closed position.

A fire rated pet door closure and assembly adapted to be mounted on the attached garage side of a fire wall or fire door in part defining an enclosure such as a house or living area over a pet door access passageway opening from the inside of the fire wall or fire door to the outside thereof which pet door is normally selectively open, for pet egress. The onset of a fire/heat emitting emergency mechanical fusible apparatus is provided such that the fire rated pet door closure supporting release link apparatus with a predetermined release temperature activates a latch support for the fire rated pet door closure panel which automatically closes via gravity sealing the pet door access passageway with intumescent smoke and draft seals.

There is provided a ceiling panel for a pod room. The ceiling panel comprises one or more cover components movable between an open configuration and a closed configuration; and an actuation mechanism configured to move the one or more cover components from the closed configuration to the open configuration in response to a trigger. The ceiling panel may provide a specified percentage open area in the open configuration. The ceiling panel may be adapted to acoustically insulate the pod room in the closed configuration.

A thermal door release system is provided that includes a plurality of temperature sensors arranged within multiple environments; a controller; and a release apparatus; wherein the controller, using data from the temperature sensors, monitors the temperatures of the individual environments and when a temperature for an environment reaches a set temperature threshold for that environment, causes an action such as the release apparatus to operate a door to a specified position. The set points and actions to be taken can be set per environment by a user, such that different environments will have different set points. In an embodiment, the system can support staged logic such that at various different user-defined set point temperatures for an environment, specified actions can be taken, for example, sending an email to the facilities manager when the temperature is significantly above normal and closing the door when it reaches a higher set point value.

A fire and smoke actuator includes a temperature sensor for sensing an operating temperature of the fire and smoke actuator, a drive motor, an actuator output for coupling to the damper in order to move the damper between the open position and the closed position and a drivetrain that is operably coupled between the drive motor and the actuator output. The drive motor, when activated, is configured to actuate the actuator output, via the drivetrain, to move the damper between the open position and the closed position. A drive circuit is operably coupled to the drive motor and the temperature sensor and is configured to activate the drive motor to move the damper between the open position and the closed position at a non-zero speed that is based, at least in part, on the operating temperature sensed by the temperature sensor.
