As mentioned earlier, one physical difference that distinguishes the SCE series alarms from other alarms is the embedded socket that accepts a standard euro-style terminal block. This terminal block system offers a finger-proof safe connection that is a quantum leap in safety for protecting technicians and operators from shock and shorting. If personnel safety is not enough of a reason to use these alarms, then users can count on the time and labor savings due to the ease of making the electrical connection to the alarm. Just insert pre-stripped wire ends into the terminal block and then tighten the terminal block’s screws to make the secure electrical connection.
