A detection system () for hazard detection is provided. The detection system () includes a control loop (); an addressable base unit () connected to the control loop (), the base unit () including a first near-field communication module () storing a unit address; and a mounting unit () removably coupled to the base unit (), the mounting unit () including a second near-field communication module () operable to read the unit address from the first near-field communication module () and store the unit address so that the mounting unit () is thereby addressable via the control loop ().

Detection system with addressable units

A fire system for a building is provided, the fire system including a fire panel for monitoring the building and activating an alarm; and a plurality of remote units electrically connected to the fire panel in a circuit having a loop configuration. At least some of the plurality of remote units including an indicating device for modulating a current in the circuit. The plurality of remote units are in communication with the fire panel in a master-slave relationship. The fire panel includes a calibration module for polling each indicating device to obtain a current response value and for storing said current response values, the current response value of an indicating device being based on the amplitude of the current when modulated by that indicating device.

Fire system with current response calibration

A fire detection system () includes a plurality of smoke detectors () positioned for detection of smoke within one or more smoke detection volumes (). The fire detection system () is configured to monitor occupancy of the smoke detection volumes () or to receive data indicative of occupancy of the smoke detection volumes (), for example from an intrusion detection system (). The fire detection system () is configured to adjust a smoke sensitivity associated with each of the smoke detectors () based on the occupancy of the respective smoke detection volume (), with the smoke sensitivity being decreased when the respective smoke detection volume () is occupied.

Adaptive fire detection

Provided are electronic door locks, systems, and computer implemented methods of use. In one example, the electronic door lock includes a locking mechanism configured to change a state of a door of a room between a locked state and an unlocked state. The electronic door lock further includes a communications interface configured to communicate wirelessly or wired with one or more fire devices. The one of more fire devices are configured to transmit a wireless or wired alert signal to the communications interface in response to detecting an occurrence of fire. The electronic door lock further includes a display unit configured to display an alert upon the communications interface receiving the wireless alert signal from the one or more fire devices, and configured to display an indication as to occupancy of the room.

Door lock with display unit

A method and system of determining the location of an earth fault within a loop of devices is disclosed. Upon the detection of an earth fault within the loop comprising a plurality of devices, a first device within the loop is isolated along with a second device. While the first device and the second device are isolated, it is determined if the earth fault still exists. If the earth fault no longer exists, then determine that the earth fault is located between the first device and the second device. This can be iterated through each adjacent pair of devices in the loop to localize the earth fault between the devices.

Earth fault localization

A fire and security system includes a control panel and one or more connected device. The control panel is in signal communication with a data control loop. The connected device is in signal communication with the at least one control panel via the at least one data control loop. The connected device includes a memory unit having a free memory area that stores first data and an active memory area that stores second data different from the first data. In response to operating the connected device according to the second data, the at least one connected device receives updated data delivered by the at least one of the control panel over the data control loop, and replaces the first data stored in the free memory data with the updated data.

Fire and security system including addressable loop and automatic firmware upgrade

A smoke detector systemis disclosed, including a beam detector unithaving a moveable portioncomprising at least one light transmitter, a base portion for fixing to a surface, and a motor configured to rotate the moveable portionrelative to the base portion. The system also has at least one receiver for detecting light transmitted by the transmitter.

Beam smoke detector system

A point detector () for a fire alarm system. The point detector () includes a fan () configured to aspirate air from a surrounding environment; and an inlet () in flow communication with the fan (); the inlet () is configured to split the incoming flow into multiple streams (); and each stream () of the multiple streams () is configured to be in flow communication with a respective sensing device ().

Point detector for fire alarm system

A fire alarm includes comprises a central fire alarm control panel for monitoring the building and activating an alarm; and multiple remote units for distribution within the building, the remote units including indicating devices for determining conditions that are indicative of a possible emergency. The multiple remote units are in communication with the fire alarm control panel in a master-slave relationship such that the fire alarm control panel will receive inputs from the indicating devices and activate the alarm when those inputs indicate a possible emergency. In addition, the remote units include a secondary communication system for communication between remote units in a degraded mode of operation that occurs in the event of a failure of the master-slave communications with the fire alarm control panel, the secondary communication system including a transceiver arrangement at each remote unit for providing a wireless mesh network between the multiple remote units.
