synchronization module shall be provided to allow simultaneous operation of
multiple metal detection subsystems, with no degradation of sensitivity or
function, when separated by 1.5 m 5 feet or more. The metal detector shall
not adversely affect magnetic storage media.
2.9.2.1
Size and Weight
Freestanding metal detectors shall not exceed 1.0 m deep, by 1.3 m wide, by
2.3 m high 40 inches deep, by 50 inches wide, by 90 inches high. Metal
detectors to be used in entry control booths shall have dimensions as
needed to fit inside the entry control booth. The metal detector shall
weigh 160 kg 350 pounds or less.
2.9.2.2
Local Alarms
The metal detector shall provide local audible and visual alarm
annunciation. Alarms generated by the metal detector shall be immediately
communicated to and annunciated at the central station.
2.9.2.3
Material Identification and Sensitivity
The metal detector shall have a continuously adjustable sensitivity control
which allows it to be set to detect 100 grams of ferrous or non-ferrous
metal placed anywhere on or in an individual's body.
2.9.2.4
Traffic Counter
**************************************************************************
NOTE: If traffic counters are not required,
eliminate this paragraph.
**************************************************************************
The metal detector shall include a built-in traffic counter with manual
reset capability. The traffic counter shall be sensor actuated and shall
automatically increment each time a person passes through the metal
detector. The metal detector shall also provide visual prompts directing
the individual to proceed through the metal detector at the proper time or
to wait until the metal detector is reset and ready for another scan.
2.9.2.5
Electrical
The metal detector shall not dissipate more than 250 Watts. Neither the
metal detector's sensitivity nor its functional capability shall be
adversely affected by power line voltage variations of plus or minus 10
percent or less from nominal values.
2.10
ENTRY CONTROL SOFTWARE
2.10.1
Interface Device
The entry control software shall control passage. The decision to grant or
deny passage shall be based upon identifier data to be input at a specific
location. If all conditions are met, a signal shall be sent to the input
device location to activate the appropriate electric strike, bolt,
electromagnetic lock or other type of portal release or facility interface
device.
