ADT pull station at White Marsh Mall, outside Baltimore, Maryland.
The fire alarm system for this mall appears to be original to the facility's construction in 1981, and contains this model of pull station throughout the main body of the mall. The original notification appliances appear to be Wheelock 7002 horn/strobes. However, as these have worn out over the years, they have been replaced by other, more modern notification appliances, leading to a mixture of many different styles and manufacturers of notification appliances throughout the mall, including devices by Wheelock, Gentex, and System Sensor.
