A retrofit module for lithium battery passivation, detection, activation and maintenance (PDAM) may include a test circuit, a load circuit, a microcontroller and means for electrically connecting the PDAM module to a target battery in a device. Upon power-up and/or joining or rejoining a network, and additionally at periodic intervals thereafter, the state of the target battery is determined and an activation algorithm is executed, the parameters of which are dependent upon the determined target battery state.

Lithium battery passivation detection, activation and maintenance module

An emergency alarm system peripheral, such as a hazard detector, intrusion detector, or a notification appliance, includes a base that is permanently installed on a wall or ceiling, and a head which mounts to the base. Various embodiments and methods are provided to easily and efficiently assign addresses to the peripherals in the system.
