SM120X

RELAY / POWER SUPPLY MODULE

READ INSTRUCTIONS CAREFULLY AND COMPLETELY BEFORE INSTALLING.

Electrical Rating: 120V AC 60 HZ 0.08 AMP
Contact Rating: 10 AMPS @ 120 VAC

DC Output: 5 MA Max. (CURRENT LIMITED)

DESCRIPTION:

This module is only activated by a smoke alarm interconnect signal.

The relay portion of this module can be used to activate auxiliary warning devices such
as external bells and sirens,hallway or stairwell lighting. It provides isolated, (no internal
connection to 120 volts AC) normally open, and normally closed contacts.

The power supply portion can be used to connect spot type heat detectors (Rate of rise
or combined rate of rise and fixed temperature only) and manual pull stations
with interconnected multiple station alarms.

WARNING! Alarm and module wiring must conform to the electrical codes and local
codes in your area. In USA, it includes articles 210 and 300.3(B) of the U.S. National
Electrical Code ANSI/NFPA 70, and NFPA 72. The multiple station interconnect wiring to
the alarms must be run in the same raceway or cable as the AC power wiring. In addition,

resistance of the interconnect wiring shall be a maximum of 10 ohms.

the
All wiring should be performed by a licensed electrician. The module should be installed

in a UL listed junction box that has sufficient volume for proper installation. The electrical
circuit used to power the alarms and the module must be a 120 volt ac 60hz circuit which
cannot be turned off by a switch or a ground fault interrupter, it must be on 24 hours

a day. Since this module is 120 volt AC powered, it will not function during
an AC power failure, even if it is being used with the model 1275, 1275CA, 1276,

1276CA, 1285, 1285CA, 1296, i12040, i12040CA, i12060, i12060CA, i12080, PE120,
PE120CA, PI 2000, PI2000CA, KN-COSM-IB, KN-COSM-IBCA, HD135F, and HD135FCA,
alarms which have battery backup power.

WARNING: This device cannot be operated from power derived from a square wave,
modified square wave or modified sine wave inverter. These type of inverters are
sometimes used to supply power to the structure in off grid installations,such as solar or
wind derived power sources. These power sources produce high peak voltages that will
damage the device.

IMPORTANT: Whenever alarms and modules are interconnected they must be powered
from a single
wire as required by codes in your area. Do not use more than 1000 feet of wire
between the first and last device in the multi station system.

INSTALLATION INSTRUCTIONS:

This module should be installed in a UL listed junction box. All connections should be
made by a qualified electrician in accordance with the requirements of the national
electrical code and/or any other local codes having jurisdiction in your area.

Turn off the main power to the circuit. If you are also installing smoke alarms, heat
alarms, or CO alarms, wire them according to their specific owner’s manual. Refer to the
typical installation diagrams (Figures 1-4) included in this manual for your specific
application.

Connections on the Relay /Power Supply Module:
Black Wire AC Hot
White Wire AC Neutral
Red Wire Interconnect Signal
Blue Wire Common Contact
Yellow Wire Normally Closed Contact
Orange Wire Normally Open Contact
Gray Wire 9-Volt DC Output (5MA Max.)

After all connections are made, place the module inside a UL listed junction box, where the
alarm is installed, or in a remote location and use the appropriate electrical

CAUTION: The model SM120X should not be used to connect groups of alarms to a fire
alarm panel or to interconnect groups of fire alarms together.

Residential alarms do not latch in the alarm condition and they are self-resetting. If an
alarm connected to a module has the test button pushed or the alarm momentarily
activates, it will activate the module for as long as the unit is in alarm. If more than one
alarm is connected to the module and the module is tied to a control panel there will be no
way of knowing which unit caused the alarm.

box cover.

The model SM120X module is for use with the following interconnectable models: Smoke
Alarms: 1235, 1235CA, 1275, 1275CA, 1276, 1276CA, 1285, 1285CA, 1296, i12020,
i12020CA, i12040, i1240CA, i12060, i12060CA, i12080, PE120, PE120CA, PI2000, and
PI2000CA, RF-SM-ACDC, CO/ Smoke Combo alarms: KN-COSM-IB and KN-COSM-IBCA,
and Heat Alarms, HD135F, and HD135FCA, all with red interconnect wires. Each module
is equivalent to one interconnect alarm, reduce the maximum number of interconnect
devices by one for each module used. Do not exceed the total number of devices
allowable in the interconnect system,
maximum number of units allowed when interconnecting. Do not exceed the
temperature or humidity limits of +40°F (4.4°C) to 100°F (37.8°C) (such as in garages
and unfinished attics) and 90% relative humidity for either the relay module or the
alarms.

NOTE: Only the Smoke portion of the: KN-COSM-IB and KN-COSM-IBCA combo alarms
will activate this module. If CO alarm models, KN-COB-IC, KN-COB-IC-CA, KN-COB-ICB­CA, KN-COP-IC, KN-COP-IC-CA are included in the interconnect system, they will not
activate the SM120X module.

ATTENTION: The wiring connecting the module with the external devices is not
supervised. Be sure to test the operation of all the devices controlling the module or
controlled by the module. Devices controlled by the module can be tested by pushing the
test button on the alarms and verifying that the controlled device responds in the desired
manner.

Devices controlling the module can be tested by activating the device. Test pull stations
and spot type heat detectors after initial installation and each time you test your alarms.
Verify that the pull station and heat detectors sound all your interconnected alarms.

ATTENTION: Only use spot type heat
feature, as this type can be tested to validate operation. These detectors should be

tested following the manufacturers recommended procedure. This procedure typically
recommends using a hot air source (hand held hair dryer or heat gun) directed at the
detector from approximately 1 foot away.This will activate the rate of rise portion of the
detector and sound the interconnected alarms.

CAUTION: Remove the hot air source as soon as the alarms sound. This will prevent
activating the fixed temperature portion of the heat detector. The fixed temperature
element is a one-time device. Once activated it will not reset and the detector will have
to be replaced.

ADDITIONAL INSTALLATION INFORMATION: (Figures 1 and 2) If the desired function is to
switch off a device when the alarms sound, connect the yellow wire (NC) instead of the
orange wire (NO) to the supply side of the device. Be sure not to exceed the relay contact
ratings of the module. This module should not be used to control inductive loads with inrush
currents that will exceed the maximum contact ratings.

FIGURE 1 shows a typical installation of a relay / power supply module wired to switch
on 120 volt device when the alarms sound. In this configuration the common switch
contact (blue wire) is connected to the 120 volt supply. When the alarms sound the
module detects the signal on the interconnect line (red wire) and activates the relay. As
a result of this action, the orange wire (NO) supplies 120 volts to the device.

FIGURE 2 shows a typical installation of a manual pull station and a relay / power
supply module. In this configuration the module receives 120-volt power all the time. The
9-volt DC output (gray wire) is used to supply power to the pull station, and the relay
portion is used to control a 120-volt device configured to switch on when the module is
activated. The pull station switches the 9 volt signal from the module back into the
interconnect line.

FIGURE 1

Activating the pull station will sound the alarms and activate the relay portion of the
module.The common terminal of the switch contact (blue wire) is connected to the 120­volt supply. When the alarms sound or the pull station is activated the module detects
the signal on the interconnect line (red wire) and activates the relay. As result of this
action, the orange wire (NO) supplies 120 volts to the device.

FIGURE 3 and 4 show the typical installation of a relay / power supply module and a
manual pull station or a spot type heat detector, interconnected with multiple station
alarms. In both of these configurations the connected device (manual pull station or spot
type heat detector) switches on the AC power to the module when the device is
activated. The module then supplies the DC interconnect signal (gray wire) needed to
activate all of the interconnected alarms.

NOTE: The switch contacts in the Pull Station or the Heat detector must be rated for 120
volts in this application.
