2.1.3
Nameplates
Laminated plastic nameplates shall be provided for local processors. Each
nameplate shall identify the local processor and its location within the
system. Laminated plastic shall be 3 mm 1/8 inch thick, white with black
center core. Nameplates shall be a minimum of 25 by 75 mm 1 by 3 inches,
with minimum 6 mm 1/4 inch high engraved block lettering. Nameplates shall
be attached to the inside of the enclosure housing the local processor.
Other major components of the system shall have the manufacturer's name,
address, type or style, model or serial number, and catalog number on a
corrosion resistant plate secured to the item of equipment. Nameplates
will not be required for devices smaller than 25 by 75 mm 1 by 3 inches.
2.1.4
Fungus Treatment
**************************************************************************
NOTE: Fungus treatment should only be used on
equipment to be installed in climates that are known
to cause problems with fungus growth. Examples are
extremely tropical climates or humid, poorly
ventilated areas. If these conditions do not exist,
delete the fungus treatment requirement.
**************************************************************************
System components located in fungus growth inductive environments shall be
completely treated for fungus resistance. Treating materials containing a
mercury bearing fungicide shall not be used. Treating materials shall not
increase the flammability of the material or surface being treated.
Treating materials shall cause no skin irritation or other injury to
personnel handling it during fabrication, transportation, operation, or
maintenance of the equipment, or during use of the finished items when used
for the purpose intended.

Tamper Provisions
2.1.5.1
Tamper Switches
Enclosures, cabinets, housings, boxes, and fittings of every description
having hinged doors or removable covers and which contain circuits or
connections of the intrusion detection system and its power supplies, shall
be provided with cover operated, corrosion-resistant tamper switches,
arranged to initiate an alarm signal when the door or cover is moved. The
enclosure and the tamper switch shall function together in such a manner as
to not allow direct line of sight to any internal components before the
switch activates. Tamper switches shall be inaccessible until the switch
is activated; have mounting hardware so concealed that the location of the
switch cannot be observed from the exterior of the enclosure; be connected
to circuits which are under electrical supervision at all times,
irrespective of the protection mode in which the circuit is operating;
shall be spring-loaded and held in the closed position by the door or
cover; and shall be wired so that they break the circuit when the door or
cover is disturbed.
a.
Nonsensor Enclosures: Tamper switches on nonsensor enclosures,
which must be opened to make routine maintenance adjustments to
the system and to service the power supplies, shall be
push/pull-set, automatic reset type.
b.
Sensor Enclosures:
Tamper switches on sensor enclosures, which
