limited circuits only. Wiring from these terminals must be in conduit and contained within one room.
Power limited and non-power
limited circuits must be separated by at least .25” within the enclosure
and run in different conduit. The contacts are rated at 24Volts D.C. 1 Amp resistive. Acceptable wire
size for connection is 16-22awg. Note: When Alarm C is designated for sprinkler supervisory these
relays outputs will not activate during a sprinkler supervisory alarm even if programmed to do so.
Refer to the programming section for programming options and instructions.
5.1.4 Trouble Input (TB4 Terminals 3+4)
The trouble input is used when connecting the Keltron SDACT(-2) communicator to the CP-3500D.
Connect it to the N.C. trouble output relay on the SDACT(-2). When the SDACT(-2) has a trouble
condition the input will detect an open circuit and display a dialer trouble as described in section
6.2.5. The trouble condition caused by this input will self-restore when the fault is corrected. This is a
non-power limited circuit. Wiring from these terminals must be in conduit and contained within one
room. Power limited and non-power
limited circuits must be separated by at least .25” within the
enclosure and run in different conduit. Acceptable wire size for connection is 16-22awg. Refer to
section 7 for more information and proper connection of this input.
5.2 NAC Auxiliary and Other Outputs
5.2.1 Auxiliary Output Local Energy Municipal Box Service (TB4
Terminals 1+2)
This is a programmable output for connection to a city municipal box using series connection only.
Shunt connection is not supported. This is a non-power limited connection. Power limited and non-
power
limited circuits must be separated by at least .25” within the enclosure and run in different
conduit. Refer to figure 4 for suggested wire routing. This output is supervised for open circuit and
ground fault.
Note: The wiring integrity of the aux output is only supervised if it is programmed
to activate.
One of the alarm types A or B or C or D can be programmed to activate this output. A
jumper labeled JP1 located on the CP-3500D motherboard can be used to disable the auxiliary
output. Placing the jumper on pins 1+2 will disable the output. This is useful when tripping of the
municipal box is not desired while performing system testing in normal operation mode. Disabling this
output will cause a system aux trouble to be displayed. Removing the jumper completely or placing it
on pins 2+3 will enable the output to function if programmed. Note: The auxiliary output must first be
programmed to activate before the auxiliary output will function. There are multiple activation and
reset options available when this output is used. Refer to the programming section for further
instructions. Note: Alarm C will not activate the auxiliary output when it is designated as sprinkler
supervisory even if programmed to do so.
Output Ratings:
Alarm current 350 ma.
Alarm voltage 3.65 Vdc
Coil resistance 14.5 ohms
Max. coil resistance 14.6 ohms
Max. wire resistance 3 ohms
Ground Fault detection resistance 1000 ohms or less
Note: The following rules must be followed when wiring to the Auxiliary output:
1. The wiring from the Aux. output to the city box must be less than 1000 feet.
2. The wiring must be underground.
3. The wiring must be run in a separate trench from power lines.
