Most fire detectors currently available are poweredby 9 volt DC transistor radio batteries, 120 volt AC power wiring, or 120 voltAC power with battery backup. Wired in smoke detectors connected to a fire orsecurity system are usually powered by DC from the security panel. This givesthe detectors a natural battery backup in the event of a power failure. Commonvoltages are 6v, 12v, and 24v DC with 12v DC being the most common. Some 120v AC units have the capability to interconnect so that when one unitactivates, it causes the audible alarm in the other units to sound. Units canalso be purchased that have a relay output for connection to any security systemcontrol panel or wireless transmitter. The most common types available inhardware stores operate as independent sensors that are battery powered, are notconnected to the security system, and have their own audible alarm sounder. Heatsensors operate using a different technology from smoke detectors. The basicdesign features of each type are summarized in the following paragraph. Heat sensors are designed to detect a rapid rise in temperature. Theyalso have a feature that sets off an alarm when a fixed temperature is reached.

Neapolitan, may also be suitable for protection. The K9 unit mentioned above uses Belgian Malinois and the similar but rarer Dutch Shepherds because they have fewer health problems than German Shepherd Dogs and some other protection dog breeds. The increased popularity of Belgian Malinois for police work has led to a corresponding increase in their popularity generally, an effect that has been observed with other breeds, as well. Every breed ought at the very least to have a registry like that of the DPCA, but few do. As Shook discovered, it is difficult to get accurate data on health problems because many breeders of most breeds are reluctant to talk about such problems.
