Wiring
Basic Controller
The installer wiring associated with the basic controller is
connected to four removable terminal blocks on the 113B. The
types of signals on these terminal blocks fall into four categories:
• Alarm Outputs (BD, HV, ACF, MJF, MNF, PMJs and
PMNs)
• Alarm Inputs (RMJ, RMN, OS, MJF and MNF from EMJF
and EMNF)
• Control Inputs (TEQ, TEL, TF/ER and TRs)
• Miscellaneous Outputs (ABS and DG)
Three of the four terminal blocks (TB102, TB103 and TB104)
are assigned to the various office alarm outputs from the
controller. Terminal block TB101 has the connection points for
the remaining three categories of office interfaces. The signal on
each terminal is indicated on the label inside the controller front
panel. Refer to Table 4-F for a list of terminal block pin
assignments.
The terminal blocks accept 22 to 24 gauge stranded wire. Wire
terminals are not used. The wire ends are stripped and clamped
directly in the terminal blocks. Multiconductor 24 gauge
jacketed cable or 22 gauge twisted pair wire is recommended.
Alarm Outputs: The alarm outputs (BD, HV, ACF, PMNA,
PMNV, PMNE, PMJA, PMJV, PMJE, MNF and MJF) are clean
transfer contacts and are described functionally in Section 2.
Office alarm systems are designed for EITHER
closure-on-alarm or open-on-alarm, requiring two wires from
each controller alarm that is used.
Alarm Inputs: The three alarm inputs (RMJ, RMN and OS) are
compatible with battery voltage on alarm signals,
current-limited by resistors. These alarm inputs are general
purpose. They can be used to detect alarm conditions from any
auxiliary plant equipment, such as ringer, converter, inverter,
etc. The subsystems generating those alarms must be powered
off the same battery and ground system as the controller (i.e., the
dc distribution bus bars). A typical application is shown
