UL Standard 681 for Installation and Classification of
Mercantile and Bank Burglary Alarm systems requires foil
lining of equivalent protection of the control unit enclosure.
The D8108A enclosure does not have foil lining, but
acceptable protection can be provided by mounting
electronic vibration sensors inside the enclosure.
Proxim-
ity alarms (capacitance) cannot be used for this
purpose.
Install electronic vibration sensors in the D8108A enclo-
sure that are identical to those used to protect the safe or
the vault. Sentrol 5402, Potter EVD-S, or Arrowhead S-
3810 electronic vibration detection (EVD) systems which
can be mounted inside the enclosure meet the require-
ments of UL 681. Mount the electronic vibration sensor
directly inside the metal cabinet of the D8108A. Do NOT
install the sensor within a quarter inch (1/4”) of the
components or traces of the printed circuit assembly.
