QUESTIONS & ANSWERS
Ask a Question-
can I replace my DSC 410BST with the System Sensor 4WT-B 4-wire, photoelectric i3 smoke detector with a 135 Degree fixed thermal sensor
Yes, the 4W smokes are a viable replacement for 410 models. If I recall the terminal style should be very similar as well making installation pretty simple.
-
Is the 4WB-T suitable for replacing a 2812TH? Thanks.
Ther terminals between the 2 sensors will be a bit different, but yes the 4WT-B is a smoke and heat detector just like the 2812TH is. It should work fine.

I am using this in a remodel job as a single smoke-heat detector. Do I need to use an EOL relay if there is only one detector without integral siren, or can I just use 2 EOL resistors?
No system Im aware of has the capability to monitor the power wires on 4-wire smokes, and if you used a second resistor Im not sure where you could put it that would provide that supervision. You dont technically HAVE to use the EOL relay at all, but if you want to ensure the smoke is always powered, you will need it.

Is this sensor completely compatible with my DSC HS2032 Neo control board?
Yes, the 4W smokes work with all standard hardwired alarm systems.
-
can this be installed in attic with temps in the 100-110 range ?
No, photoelectric smokes such as the 2W or 4W series should not be installed in an attic because of likely falsing due to the dusty enviornment likely there., There are only for finished interior spaces. A heat detector is the proper sensor for an attic. See here:

replacing System sensor 2112/24T , will 4WT-B be current replacement ?
Yes the 4W series is the correct replacement for the System Sensor 2112 series.

I need a fire/Smoke detector to replace the one with my Radio shack Safe House security system, it calls for a 4 wire Smoke Detector supervised by a U. L. end of line module. Will any of these work for me?
I am unfamiliar with the Radio Shack system as it's quite old, but if it's specs call for a 4 wire low voltage smoke with a normally open alarm circuit, yes these will work.

What is the difference between a 4wt-b and a 4wtA-b?
The A means it has an audible sounder built into the smoke detector. That's the only difference. No sounder in this one and it relies only on the system sirens.

System Sensor 4W-B Four Wire Smoke Detector
4 wire type smoke detectors are compatible with all alarm systems, unlike the less popular 2 wire type. We're often asked which type we recommend, 2 wire type or 4 wire type. If you are going to have only a few and they will all be on one level, we recommend 2 wire type. On the other hand, if you will have smoke detectors on more than one level, will have more than a four or five, or you need them with built-in sounders we then recommend the 4 wire type.

System Sensor 4WTA-B Four Wire Smoke Detector With Built-In 135 Degree Fixed Heat Sensor & Sounder
4-wire type smoke detectors are compatible with all alarm systems, unlike the less popular 2-wire type. This model is the same as the 4wt-b model except it has a built-in sounder as well. We're often asked which type we recommend, 2-wire type or 4-wire type. If you are going to have only a few and they will all be on one level, we recommend 2 wire types. On the other hand, if you will have smoke detectors on more than one level and wish to label them individually, we then recommend the 4-wire type.

System Sensor i4 Series 4-wire Smoke / CO Detector If you're looking for an aesthetically pleasing, cost effective solution to detecting smoke and carbon monoxide then the System Sensor i4 Series Smoke/CO Combination detector is what you've been looking for.The COSMO-4W is a 4-wire smoke detector with built-in carbon monoxide detector. This is compatible with most hardwired alarm systems. You will have to use a control module. For the COSMO-4W you will use the COSMOD4W control module. The module is the interface between the detector and the panel. It allows a 2-wire or 4-wire device to communicate distinct smoke, maintenance and CO signals to the panel while reducing wiring requirements as compared to separate smoke and CO devices. The modules can handle 12 devices on a loop. In addition to that all COSMOs have a built-in sounder allowing the COSMOD module to act as a reversing relay, setting off all...
