  Interconnects Smoke Detectors (Alarms) without adding a third wire 
 
Code Setting Selects which Smoke Detectors (Alarms) are interconnected 
 
Works with your
120 VAC multi-station Smoke Detector (Alarm)   

Miniaturized feature allows quick and easy installation
 

Add on and create an ADA and HUD approved Supplemental Fire Alarm System
 

Connect your 120VAC Interconnected Smoke Detectors into your conventional low voltage alarm monitoring panel for smoke alarm monitoring, by using at least one Model TR-SAI and a Model RX-CCO.  

For buildings with a
3-phase power system, you need to install a
3-Phase Coupler/Repeater

The Model TR-SAI, Smoke Alarm Interconnect Module, allows you to interconnect Smoke Alarms (or Carbon Monoxide Alarms) so that when one is activated by smoke or fire, they all will activate, and and also activate other appliances such as Relays, Bells, Horns, "EXIST" signs, etc., without the necessity of adding a third wire. This module is both a powerline carrier transmitter and receiver. 

(This module is also available as receiver only.   Contact us )

Interconnected Smoke Alarms in multifamily dwellings (apartment houses, condos, rest homes, etc) are required by law in most places, and is a good idea in single every family homes as well, in that they can, and do, save lives. This wiring arrangement guarantees that if one alarm in the house goes off, they all go off. Even if the fire starts and is detected in the basement, attic, or connected garage, people asleep upstairs will hear the alarm. Because of this safety feature, every alarm in the house is activated. 

Normally, to interconnect smoke alarms, it is necessary to add a wire (third wire) between each of the units. In many older buildings, this could mean tearing out walls to add the third wire, which would prohibitivly expensive. This third wire is not needed with the Smoke Alarm Interconnect Module .

The electrical connections are made via 3 leads. Two are for direct connection to the 120V AC power, and the third connects to the Smoke Detectors third (interconnect) wire.

You can use the Model TR-SAI Module to connect smoke detectors in a attic, basement, or garage with those in the rest of the house.

The Model TR-SAI is mounted with each 120VAC multi-station smoke alarm. The installation is shown in the diagrams below.  The hook up is excatly the same for both Smoke Alarms and Carbon Monoxide Alarms.

These modules are designed to be hard wired into the electrical outlet box behind the Smoke Alarm (or the Carbon Monoxide Alarm). They are solidly encased in a rock hard epoxy compound, measure approximately 2.2 x 2 x 0.5 inch, weighs less than 6 oz., and come with 2-sided tape on the bottom for quick and easy installation.

The diagram above shows how the Model TR-SAI is wired into the 120VAC Quick-Connector Alarm Harness of the Smoke or Carbon Monoxide Alarm.

The operation is as follows. When no smoke or fire has been detected by any Smoke Alarm, all of the Model TR-SAI modules remain in the receiver mode. When one Smoke Alarm is activated by smoke or fire, the Model TR-SAI module connected to that Smoke Alarm immediately becomes a transmitter, and transmits the alarm to all the other Model TR-SAI modules over the 120V power wiring. Those modules that have the same code setting (DIP switch) as the transmitter will receive this signal, and will trigger their respective Smoke Alarm.

The Model TR-SAI modules works with your 120VAC multi-station Smoke Alarm, or with your 120VAC interconnectable (ones with 3 wires) Carbon Monoxide Alarm. 

The Model TR-SAI module has a DIP switch that is used to select the code. They will only respond to those modules whose code settings matches their own. All other module signals will be ignored. This allows you to select which smoke detectors will be activated together, or to have Smoke Alarms and Carbon Monoxide Alarm to operate separately just by setting different codes on the DIP switches. For example, if you wanted all the smoke detectors in one area, say the second floor, to sound only when a smoke detector on that floor is activated, you need only to set all those on the second floor to the same code. And, if you want all the smoke detectors on the first floor to sound only when a smoke detector on the first floor is activated, you need to set the smoke detectors on the first floor to the same code, but a different code from the second floor. Or, if you wanted to include both Smoke Alarms and Carbon Monoxide Alarms in your system, you would set the Smoke Alarms and Carbon Monoxide Alarms to different codes.

Supplemental Fire Alarm System

When using the Model TR-SAI Module to interconnect Smoke Detectors, you can create an ADA and HUD approved Supplemental Fire Alarm System for those with hearing impediments that may make it difficult to hear a conventional fire alarm with normal household noises from televisions, radios, etc., by plugging-in the Model RX-BZM , Buzzer Modules (set to the same code as the Model TR-SAI's) at any electrical outlet in living quarters or where an alarm is required (Hallways, Stairways, Bathrooms, Common areas, etc.). The Buzzer will sound (90db " beeping ") whenever any of the Smoke Detectors are activated by smoke, since this alarm signal is present on the electrical wiring throughout the building. You may add on additional Strobes, Horns, or other Fire Appliances as required, using the Model RX-RAM , Model RX-RCM , or Model RX-CCO . The Supplemental Fire Alarm System can be triggered by hand using a Model TX-PBT , Pushbutton Transmitter.

Also, you can connect your Smoke Alarm System into a conventional Alarm Panel for remote monitoring, by using at least one Model TR-SAI, and a Model RX-CCO or Model RX-RCM .
