contact devices and more than one has been placed in the unlock
condition while the interlocks are active, upon resecuring of the
original hardware one and only one of the additional doors shall
open in response to the multiple unlock switch position. Upon
simultaneous operation of central devices in an interlock scheme,
one and only one shall cause a hardware set to become nonsecure.
c.
Monitored doors and gates: Doors which are equipped with hardware
which monitors the secure status and are not electrically
operated, shall be monitored in the following manner: The door or
gate red LED shall function as specified for annunciation above,
except as described in this paragraph. Control panels monitoring
monitored-only doors and gates shall provide night secure
provisions. The night secure provisions shall secure all doors
and gates unless specific groups are required. Once the doors or
gates are secured, this function shall alert the control officer
of unsecured conditions. Pressing the night secure switch on
membrane switch panels shall cause the secure mode to become
active and the secure green LED to illuminate. Upon activation,
hardware in the nonsecure condition or hardware which becomes
nonsecure shall cause an audible alarm to sound and the status LED
for the nonsecure hardware to latch illuminated until reset.
Pressing the silence switch shall silence the audible alarm. The
secure function shall annunciate subsequent alarms audibly and
visually in the manner specified above. Pressing the secure reset
switch shall release latched indicators, extinguish the secure
green LED, and return the panel to normal operation.
d.
Shower and cell call-in: For the shower and cell doors in the
pretrial and female areas, the following operation shall apply:
Pressing the momentary action pushbutton in the cell or shower
shall cause an amber LED associated with the cell or shower on the
locking control panel to flash and an audible signal shall sound.
Pressing the control panel momentary action silence switch on the
control panel shall silence the audible signal and cause the LED
to illuminate constantly. Pressing the control panel momentary
action call-in reset switch shall extinguish the LED. Once an
individual cell or shower has been received at the control panel
and has been silenced, additional activations of the same cell or
shower call-in switch shall have no effect. Silencing one call-in
shall not inhibit other calls from being received.
e.
Control panel enable/disable keyswitch: The locking control panel
located at the reception counter shall be equipped with a
keyswitch mounted on the front that shall enable and disable the
locking panel control functions.
1.2.3
Battery Power
Provide batteries, complete with charging system as back-up power, in the
event of a utility and emergency power failure. Provide adequate capacity
to supply locking control system electrical load for a period of four
hours. On restoration of utility or emergency power, the batteries shall
automatically be recharged. Battery backup shall provide power to support
input status and LED annunciations, output controls, and memory retention.
Battery backup power is not required for power source which actually
operates the locking door or gate hardware.
