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.
