2.10 Internal Circuits Window
Overview
The Internal Circuits Window (see Figure 22) allows for the programming of outputs, LEDs, etc.
for the various internal circuits (functions) of the Control Panel. Internal circuits 0, 71, 72, 73, 75,
81, and 82 are fire alarm functions while all others are trouble functions. All internal circuits have
specific meanings and are stored in the archive of the panel. MR-2944 and MR-2934 annunciators
only use internal circuits 51 and 52. See “4.0 Appendix A: Condition Codes and Zone Numbers” on
page 46 for a list of all the internal circuits.
Some of the internal circuits are:
• Internal Circuit 0, General Alarm: This is the General Alarm function. General Alarm can
be received from an annunciator or from an SE 2000. It can be assigned to one of the Hot
Keys of control panels. General Alarm causes all the bells and strobes on the panel to
operate in Evacuation mode. Any additional outputs, LEDs, etc. that require operation are
programmed using the Relate button.
• Internal Circuit 51, Comlink #1 Supervision: This is used for communications errors on
COM1 port of the panel or annunciator.
• Internal Circuit 52, Comlink #2 Supervision: This is used for communications errors on
COM2 port of the panel or annunciator.
• Internal Circuit 81, 1st Stage Alarm: This circuit is activated if the bells and strobes are
activated in first stage by an alarm input. Any additional outputs, LEDs, etc. that require
operation are programmed using the Relate button. If the bells have been disconnected
on the panel, this circuit will not be generated.
• Internal Circuit 82, 2nd Stage Alarm: This circuit is activated if the bells and strobes are
activated in the second stage mode by an alarm input or by a time-out. Any additional
outputs, LEDs, etc. that require operation are programmed using the Relate button. If the
bells have been disconnected on the panel, this circuit will not be generated.
• Internal Circuit 96, Fire Pre-alarm: This circuit is activated by any smoke detector in the
auto-verify process or addressable device in alarm during the Retard period. It can be
related to an LED to give a visual indication that an alarm is in the verification process.
• Internal Circuit 99, Common Trouble: This circuit is tripped by any internal circuit or
trouble condition not associated with an internal circuit that turns on the Common Trouble
LED on the panel. This circuit is used to annunciate common trouble conditions at a
remote location. This circuit is not tripped by troubles generated by input circuits or
addressable devices. This circuit is not recorded in the archive of the panel.
