3.2.2 rc~uipment enclosures. All enclosures for equipment supplied under
this specification shall ue protected against tampering by being equipped with
tamper switches or triggering ;;;echanisms electrically compatible with the alarm
system; or shall be fully filled with an epoxy compound. Internal wiring of
equipment. shall be such that the tamper switches and triggering mechanisms are
not bypassed even though the detector itself is operating in the "ACCESS" mode.
All controls which affect the sensitivity of the units shall he located inside
the tamper resistant enplosure.' Xey locks or key operated switches used to
protect enclosures shall have Underwritcrs' Laboratories listed locking cylinders.
3.2.3 Environmental reau rcmonus. All units shall be capable of. operating
in temperatures ranging prom 32 degrees F to 120 degrees F. All units shall be
capable of operating at 36 degrees F temperature and 85 percent relative humidity.
The units shall withstand the testy in 4.6.4, 4.6.5, and 4.6.6.
3.2.4 Dependability. The sensitivity and stability of all detectors shall
~?~it2,sL- the neutralization or compromise test in 4.6.2 and
be designs to -an;a '
the stability test in 4.6.3.
3.2.5 Electronic coa;nonents. To the extent practical, all electronic
components shall be the solid state type.
3.3 Detectors. All detectors shall initiate an alarm signal under any of
the follouirg conditions: (1) VTMen sensing a stimulus or condition for which
it was designed to react; (2) If primary power fails and secondary power does
not take over properly; (3) If the detector's circuitry is opened, shorted, or
grounded and if such condition is capable of compromising the device's normal
operation; (4) If a tamper switch or triggering mechanism is activated. To the
extent feasible, the device shall be designed to initiate an alarm if any part
or component fails or ages to the extent to render the detector ineffective.
Terminals shall be located within the detector enclosure and readily accessible
to permit wiring for required combinations of detector units. All controls and
terminals which are not required for operation of the detector shall not be
readily accessible.
3.3.1 Balanced magnetic switches (type I) . The switch mechanism shall be of
the balanced magnetic type and ?'a~. ~'
~inita.ate an alarm upon increase, decrease,
or attempted substitution of an external magnetic field when the switch is in the
normally secured position. The switch and magnet shall be enclosed in separate
housings of cast, nonferrous durable material and provided reasonable protection
against moisture and dust. The mechanism shall be adjusted so that the operating
gap between faces of the switch housing and the magnet housing may be adjusted
from one-half inch to one inch to accommodate installation variances. The
switch shall be electrically protected so that a sudden- surcge of voltage renter
than required for normal operation:: will create an alarm. The switch shall
be designed so an alarm is initiated whenever the switch housing is moved as much
as one inch from the magnet housing. When simulating a closed position the
switch shall be rated for a minimum of 500,000 activations without malfunction.
3.3.2 Conductive foil (type IT). This material is intended for application
to glass and other surfaces to actect surreptitious and forcible penetrations.
When properly installed and connected into an electrically supervised detector
circuit, breaking or grounding the foil shall cause an alarm to be initiated.
Foil shall not exceed 1.2 pounds in tensile strength and shall be capable of
carrying a maximum electrical current of GO milliamperes at 60 volts with a
temperature rise of not more than 1?C. Adhesive and protective coating material
necessary for application shall be provided with the foil and shall be of types
resistant to aging, moisture and temperature change. Foil for glass shall be
not more than 1/2-inch wide. Foil for other purposes shall be not more than
1 inch wide..
