4 Screw Single Reed Flush Contact +Tamper
A 4 screw flush contact designed to meet the requirements of Security Grade 2.
A microswitch provides detection of removal from the fitting recess.
A45 is easy to wire – nickel screws for the alarm reed and brass terminals for the tamper switch. Close proximity of the screws makes adding resistors a simple job for where an EOL loop is necessary. We can also supply this contact with specific resistors already wired in (see related products).
Along with fitting screws, A45 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.
