1.2.1 Integration and Services
Provide in the prisoner housing units a watchtour system with the capabilities of printing on its systems printer
a log of watchtours conducted. Provide two sets of auxiliary relay contacts for the interfacing of the interior
fire alarm system to the watchtour system printer for log of fire alarm system alarms. The watchtour system
shall consist of a series of watchtour stations auxiliary relays, a watchtour panel and printer directly wired
to each other.
1.2.2 Sequence of Operation
Where watchtour stations are indicated to be installed in a housing area, the combination of stations shall operate
in the following manner as a system. On the watchtour control panel located in the guard control station, the
touring officer shall select one of the three "watchtour start" key switches labeled "MEDICAL OFFICER," "COMMANDING
OFFICER," or "CONTROL OFFICER." Turning the "watchtour start" momentary action key switch on the watchtour panel
shall cause the amber light emitting diode (LED) and all green station LED to illuminate and a signal to be sent
to the system printer which shall print the tour start, location, time, and date. Activation of a watchtour
station shall cause a corresponding green LED on the watchtour panel to extinguish. Reset shall occur when the
last green LED is extinguished. Once all stations in the area have been activated, regardless of order but within
the time frame, a "tour complete" green LED on the watchtour panel shall illuminate and a signal shall be sent
to the system printer to print "tour complete," location, time and date. Pressing the "reset" momentary action
switch shall cause all LEDs associated with the watchtour system to turn off. Activation of a watchtour station
after a "reset" action but before a "start" action, shall have no effect. Alarm shall be generated on fifteen
minute interval at watchtour control panel to alert guard to begin watchtour.
1.3 SUBMITTALS
NOTE: Review submittal description (SD) definitions in Section 01 33 00 SUBMITTAL
PROCEDURES and edit the following list to reflect only the submittals required
for the project. Submittals should be kept to the minimum required for adequate
quality control.
A “G” following a submittal item indicates that the submittal requires Government
approval. Some submittals are already marked with a “G”. Only delete an existing
“G” if the submittal item is not complex and can be reviewed through the Contractor’s
Quality Control system. Only add a “G” if the submittal is sufficiently important
or complex in context of the project.
For submittals requiring Government approval on Army projects, a code of up
to three characters within the submittal tags may be used following the "G"
designation to indicate the approving authority. Codes for Army projects using
the Resident Management System (RMS) are: "AE" for Architect-Engineer; "DO"
for District Office (Engineering Division or other organization in the District
Office); "AO" for Area Office; "RO" for Resident Office; and "PO" for Project
Office. Codes following the "G" typically are not used for Navy, Air Force,
and NASA projects.
Choose the first bracketed item for Navy, Air Force and NASA projects, or choose
the second bracketed item for Army projects.
Government approval is required for submittals with a "G" designation; submittals not having a "G" designation
are [for Contractor Quality Control approval.][for information only. When used, a designation following the
"G" designation identifies the office that will review the submittal for the Government.] The following shall
