Mounting The Detector - Risco RK66S Manuel D'installation

MOUNTING THE DETECTOR

Determine the mounting position. Potential false alarm sources must be
accounted for when installing RK66S, Therefore:
Attach the sensor to a surface as isolated as possible from extraneous
vibrations, with close contact between the concrete surface and the detector.
For metallic surfaces, remove residual paint from sensor installation site. Do
not use silicon grease between sensor and object!
For maximum vibration detection, the concrete surface should be smooth.
Use the mounting plate (see Figure 2) when mounting on drill-resistant steel,
brick or concrete surfaces. The plate can also be welded onto metallic
surfaces.
Adjust dipswitch settings for sensitivity; time and other parameters (see
Dipswitch settings, below) for background vibration – bearing in mind the
inverse relation between detection range and sensitivity and the construction
material of the object to be monitored. Detectors with high sensitivity can be
spaced up to 5m apart on secure protected surfaces (for example, steel),
confirmed by hammer or scratch tests.
Hinged doors, such as those on safes or ATM, and other attachments without
continuous acoustic transmission paths, should be protected with their own
detectors.
Remove the cover fixing screws to separate the cover from the base, see
Figure 1(A) / 2(B).
Drill holes on the mounting surface, using the detector base or mounting
plate as a guide, as follows:

a. Ensure that the mounting surface is level to within 1/128"
(0.1mm).
b. Use the detector base as a drilling template for the three holes
(3.2 mm dia.) and tap M4 thread at least ¼" (6 mm) deep.
Deburr threaded holes in metal.
c. Fit the detector using the supplied fixing screws, see Figure 1(B).
