BICOLOR ORANGE: ZONE THAT HAD BEEN IN VIOLATION HAS RESECURED.
PRESSING RESET TOGGLE WILL CLEAR CONDITION, CHANGING LAMP TO GREEN AND
EXTINGUISHING SONALERT
2. OPTIONS
If the panel has been supplied with any of the options listed in section 1.1, explanations of the
options' functions are provided in the following sections. Section 5 explains wiring for all options
including the addition in the field of certain options that may not have been ordered with the
panel but have turned out to be needed at the time of installation.
2.1 SILENCE LATCH (OPTION "SL")
In the event of a violation condition which takes some time to resolve, the continuing Sonalert is
irritating. If the "SL" option has been installed, the sound can be extinguished by momentarily
pushing the "silence" button found next to the Sonalert. This works as follows: If the Sonalert is
not sounding, pushing the button has no effect. The Sonalert cannot be silenced in advance.
When it is sounding, pushing the button will stop it and illuminate the indicator in the button
which shows the silence latch is active and the Sonalert would otherwise be sounding. The red
indicator will continue to show the zone in violation. The Sonalert will remain silent until the
violation condition has been reset even if another zone violates. The button indicator will then
extinguish and the latch will reset. The next time a violation condition occurs, the Sonalert will
again sound and may again be silenced as before.
2.2 EMERGENCY RELEASE (OPTION "PB")
Often, for safety reasons, it should be possible to release all locks with a single control. The
"PB" option adds to the panel an illuminated, alternate action, red push button switch. In normal
operation, the red indicator in the switch is off. When the switch is pressed, it cuts off all DC
power to the locks, releasing them (the "PB" option works with fail safe locks only). The red
indicator in the switch then illuminates showing that the panel is in a state of emergency release.
Pressing the switch a second time extinguishes the indicator and restores power to the locks.
Note that when this happens, the Sonalert will sound and the reset switch will have to be
pressed. Whenever the panel boards are first powered or repowered, the reset switch must be
pressed to initialize the boards and start normal operation of the violation circuit.
2.3 ADDITIONAL MONITORING LIGHTS (OPTION "AM")
The "AM" option adds a second row of LED's (yellow) next to the bicolors. When a positive
voltage signal is input to the associated board terminal, the yellow LED comes on. At the same
time a different audible alarm sounds. For panels with the "AM" option, Securitron uses a dual
input Sonalert. It sounds a steady alert in the violation condition but sounds a pulsing alert if
any panel yellow LED illuminates. The pulsing alert can not be silenced with the silence latch if
that option has been supplied.
The main purpose for the additional monitoring capability is exit delay installations. In such
installations an exit device is mounted on each door. Pressing the exit device does not
immediately release the lock, but rather initiates a 15 or 30 second delay after which the lock
automatically releases. A specialized logic timer such as Securitron's model XDT is necessary
to accomplish the delay function. When a control panel is used in this sort of installation, the
start of the release delay period must be annunciated so that a guard can be dispatched to
the door to investigate the egress attempt. The yellow indicator together with the pulsing
Sonalert perform this function.
