2.10 Internal Circuits Window - Secutron MR-2200 Programming Manual

2.10 Internal Circuits Window

2.10.1 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 Appendix A: Condition Codes
and Zone Numbers on page 52. 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.
