TABLE 2 DESCRIPTION.
+12 and GND: +12 VDC and GROUND input, respectively.
TIP and RNG: Telephone T1 and R1, respectively (usually brown and gray on RJ-31X, respectively.)
TRIP: Trip input into the module. Positive or negative edge. Set edge with SW6. Maximum input voltage should not
exceed 14VDC. Consult factory for assistance with your equipment.
ANS HGUP: This input is only used when it is desired to operate the 1241 as a Hands Free "Speaker Phone" in
addition to its normal function. Connect GND and ANS HGUP to a Normally Open switch (if desired). Also used
when using Model 1405 Activation Module. See paragraph 4.3.
N.C. and N.C.: Normally Closed relay contacts for local alarm silencing. These contacts duplicate pins 4 and 5
(yellow & green wires) of P1. During Two Way, this connection is opened. This relay is used to disconnect a local
alarm for Two Way. If the additional contacts are required to release an additional annunciator, the contacts on P1
must be used via accompanied relay cable assembly, P/N 117000.
MIC1: The function of this terminal is dependent on P3. If P3 is set on pins 1 and 2, this is the signal input for an
electret microphone. If P3 is set on pins 2 and 3, then this is the signal input for a power microphone (low impedance
microphone). See Paragraph 3.3 for details.
MIC POWR: This is power output for all electret microphones, or any microphone which use +5 VDC for power.
MIC2, MIC3 and MIC4: These are the inputs for electret microphones (Eagle Model 2101). These inputs are
amplified on the module. Any combination of inputs may be used (including terminal MIC1).
SHLD: This is the ground for all electret microphones. This may also be used for a ground connection for a power
microphone.
SPK and SPK: These are the talk-back speaker outputs. Speakers with a minimum of one watt power rating are
recommended (Eagle Model 2150). The total impedance of the speakers connected to these terminals must
be 8 ohms or more. See DIAGRAM 1 for multiple speaker connections.
GREEN GROUNDING WIRE: The 1241 requires EARTH GROUND for lightening protection. Connect EARTH
GROUND to this wire. EARTH GROUND must be connected to maintain warranty! Failure to connect will void
warranty!
WARNING!: DO NOT CONNECT AC VOLTAGE TO +12 AND GND - DAMAGE WILL OCCUR!
NOTE: It is recommended to connect the 1241 to the premise side of the RJ-31X. If using the
ring detect mode and the communicator/alarm panel has a download feature (which is
being used), the 1241 must be connected across the street side of the RJ-31X and the
communicator must be programmed to answer the phone a minimum of one ring before
the 1241 is programmed to answer the phone.
NOTE: Shielded wire must be used for all remotely mounted electret microphones!
WARNING: Earth Ground must be connected for proper lightening protection!
Failure to connect voids warranty!
