Grade: 2
Model: A452K24K7
A 4 screw flush contact designed to meet the requirements of Security Grade 2.
A microswitch provides detection of removal from the fitting recess.
This variant of the A452K24K7 is supplied with prefitted 2k2/4k7 resistors suitable for most Cooper, Scantronic, Menvier, Texecom, Castle & Pyronix security panels. Use of these resistors is optional.
Along with fitting screws, A452K24K7 is also supplied with a contact sheath – useful for installations where the fitting recesses have drilled a little wider than 20mm or are otherwise awkward.
