A system includes a fire panelhaving a loop driver. A combined detection and suppression loopis connected to the loop driver. A plurality of fire detection devicesand a plurality of fire suppression devicesare coupled to the detection and suppression loop. The fire suppression devicesincludes multiple sprinkler devices, each of the sprinkler devicesincluding a sprinkler bulband a circuit. The circuitof the sprinkler deviceis detectable via the fire panelusing the detection and suppression loopin order to provide information from the sprinkler deviceto the fire panel

Fire system

A method and system for updating firmware of a device. A method includes receiving a decryption engine for decrypting encrypted firmware, loading the decryption engine into a first memory of a device, and receiving the encrypted firmware. The method may include obtaining a pre-stored encryption key from a second memory of the device, wherein the second memory is a different type of memory than the first memory, and decrypting the encrypted firmware using the encryption key and the decryption engine, wherein the decryption of the encrypted firmware occurs in the first memory.

Secure device update by passing encryption and data together

A method of updating firmware stored in a non-volatile memory of a controller is disclosed. The non-volatile memory includes a first set of memory blocks configured to store a bootloader for the controller. The method includes storing a bootloader update application in a second set of memory blocks of the non-volatile memory, and storing a jump code in an initial memory block of the first set of memory blocks, wherein the jump code comprises an instruction to jump to an initial memory block of the second set of memory blocks.

Failsafe update of bootloader firmware

A fire detection apparatus includes a fire detector () including an integrated sounding device () that is configured to emit a sound () from the fire detector () and that is further configured to detect reverberation of the emitted sound resulting from a cover () placed over the fire detector (). The detected reverberation can be used to determine that the fire detector () has been covered.
