The Qolsys QS7134-840 IQ Hardwire 16-F w/ Large Enclosure is a wired to wireless system converter that transmits signals at the 319.5 MHz frequency. By using this module, you can bring over your existing hardwired sensors and use them with your 319.5 MHz wireless security system.

The way that the Qolsys IQ Hardwire 16-F works is very simple. It has 16 on-board zone terminal pairs for connecting hardwired sensors. Each zone features its own LED light to assist with enrollment and troubleshooting. A resistor must be used at each zone. In Legacy Mode, the QS7134-840 can be calibrated to use 1k to 10k resistors that are wired in parallel (NO) or series (NC). This differs from the older-style QS7133-840 that was restricted to only supporting 4.7k resistors (Yellow-Violet-Black-Brown-Brown). However, all versions of the Qolsys IQ Hardwire 16-F come with the same 4.7k resistors that must be used to meet UL Standards for fire protection. These resistors work great, so it is advised that you just use the included ones to avoid any possible confusion.

For primary power, the Qolsys IQ Hardwire 16-F uses its included 16VDC transformer. This transformer features an attached power cable for connecting with the module. On the cable, the wire with the grey dashes is the positive (+) connector. The unmarked wire represents the negative (-) connector. If you damage the transformer or the attached cable, then you will need to get a replacement 16VDC transformer.

Please note that the Qolsys IQ Hardwire 16-F module does not come with a backup battery, and you will need to add one separately. The battery should be either 12VDC 5Ah Min or 12VDC 8Ah Max. We recommend either the UltraTech 1240 or the UltraTech 1270 for this purpose. A battery harness is included with the Qolsys IQ Hardwire 16-F, so you will be able to connect the backup battery right away. Each Qolsys IQ Hardwire 16-F module will need its own backup battery, so keep that in mind if you decide to use more than one module with your system.

When installing the module, make sure you connect the sensors and resistors before connecting the transformer and backup battery. Once you have properly connected all the sensors, resistors, the backup battery, and the transformer, you will then need to enroll the IQ Hardwire 16-F module with your wireless 319.5 MHz panel. The original IQ Panel 2 and 319.5 MHz IQ Panel 2 Plus Systems view the IQ Hardwire 16-F as a "Hardwire Translator". After you have enrolled the panel, you can then individually enroll your wired sensors into wireless zones on the system. Each hardwired terminal pair on the module will represent a single wireless zone on your 319.5 MHz system. For more information on bringing hardwired sensors to a 319.5 MHz system using an IQ Hardwire 16-F, please check this great FAQ.

It is important to note that the Qolsys IQ Hardwire 16-F will utilize Qolsys S-Line Encryption when paired with an original IQ Panel 2 or an IQ Panel 2 Plus w/ 319.5 MHz Daughtercard. This is the same rolling code encryption used by the Qolsys S-Line Sensors. This rolling code encryption is great at preventing wireless hacking or takeover attempts that could prevent non-encrypted devices from working properly. If the Qolsys IQ Hardwire 16-F is used with a different wireless 319.5 MHz system, then it will operate as a non-encrypted wireless converter.

As mentioned earlier, there are 16 wired zones on the Qolsys IQ Hardwire 16-F. Zones 1 thru 15 are for standard security and environmental sensors. These devices include door/window contacts, motion sensors, glass break detectors, flood sensors, temperature sensors, and more. You can also technically connect a 2-wire heat detector to any Zone 1 thru 15 by wiring it as a Normally Open (NO) Zone with the resistor wired in parallel. Note that 4-wire smoke detectors and wired carbon monoxide sensors cannot be used with the IQ Hardwire 16-F in any way.

A unique aspect of the Qolsys IQ Hardwire 16-F is its 16th and final zone. This is a special zone that can support 2-wire smoke detectors, including the System Sensor 2W-B, 2WT-B and 2WTA-B models. This is done by wiring up to ten (10) 2-wire smoke detectors at Zone 16 in Parallel. Please note that different smoke detector models should not be mixed on this zone. Additionally, you will want to wire in your smoke detectors before trying to enroll the IQ Hardwire 16-F to your panel as a Hardwire Translator. Make sure to put your system on test mode and test your smoke detectors after enrolling. Remember that a resistor is required at this zone as well. For more information on using 2-wire smoke detectors with a Qolsys IQ Hardwire 16-F, please review this FAQ. If you do not use 2-wire smokes with the converter, then Zone 16 can be used as any standard hardwired zone for converting to wireless.

You will also want to consider the maximum power output for the Qolsys IQ Hardwire 16-F. The module can support up to 500 mA of power for wired sensors that require electrical current. Some wired devices that require power include motion detectors and glass break sensors. As long as you keep the total maximum current load under 500 mA, you will be fine.

In addition to its 500 mA power output, the Qolsys IQ Hardwire 16-F also has an auxiliary relay output rated at 12VDC 500 mA. This auxiliary relay output is great for adding an external siren to your system. However, you should be aware that it is only possible to use the Qolsys IQ Hardwire 16-F as an automatic auxiliary relay output if the module is being used with a Qolsys IQ Panel 2 or IQ Panel 2 Plus w/ 319.5 MHz Daughtercard that is running RF PIC Version 11.1.4 G2 or higher. There is no way to upgrade an IQ2 System that is running a lower RF PIC Version, so you would need to replace the panel if you wanted to use the IQ Hardwire 16-F as an automatic wireless siren relay. You can check the RF PIC Version on an IQ Panel 2 or IQ Panel 2 Plus by pressing the small grey bar at the top of the main system screen and choosing Settings > Advanced Settings > Installer Code (default is 1111) > About > Hardware > RF PIC Version. Please note that you can still use the output manually (not as an automatic relay) regardless of the panel's RF PIC version. For more information on using a wired siren with a Qolsys IQ Hardwire 16-F, please check this helpful FAQ.

In addition to the standard Qolsys IQ Hardwire 16-F module, this product also includes a large plastic enclosure for housing up to two (2) Qolsys IQ Hardwire 16-F Converters and their respective backup batteries. This large enclosure makes it easy to contain multiple 16-F modules and backup batteries in one convenient and organized location. Please note that the Qolsys QS7134-840 includes only one (1) IQ Hardwire 16-F module, even though the included large enclosure can house up to two (2). If you need a second IQ Hardwire 16-F module, then we recommend buying the Qolsys QS7133-840 IQ Hardwire 16-F that comes housed in a small enclosure. You will be able to take that IQ Hardwire 16-F module and put it inside the large enclosure provided with the QS7134-840.

The Qolsys IQ Hardwire 16-F itself measures 5.5"L x 3.5"W. The large plastic enclosure measures 16"L x 14"W x 3"D. The plastic enclosure is extremely tough and not prone to easy destruction. It has space for two (2) sets of Qolsys IQ Hardwire 16-F modules and backup batteries. You can use this enclosure to keep all your wiring super neat and organized. The enclosure comes with a tamper switch that is already pre-wired. This tamper switch does not require a resistor. The tamper switch is useful if you want your system to be alerted if someone opens the enclosure. If you want to disable this feature, you can shunt the tamper terminals with a piece of wire.

The enclosure can be fitted with an optional cam lock for added security. Battery brackets come included for keeping your backup batteries properly secured. The QS7134-840 also comes with an RF antenna, which should be connected to the converter module at the terminal marked ANT. The antenna should pass through an opening at the top of the enclosure, and it should be kept away from any obstructions, such as large metal objects, that may disrupt communication. The operating temperature for the Qolsys IQ Hardwire 16-F ranges from 32°F to 122°F. It is for indoor use only.

Note: In July of 2021 Qolsys sent out a notice regarding false tamper events on some Qolsys Hardwire 16-F units. You can read about that notice and determine if you have a unit that might be affected in this blog post.

Note: Qolsys sensors operate at 319.5 MHz. They will not work with the 345 MHz and the 433 MHz versions of the Qolsys IQ Panel 2 Plus. They are designed for the 319.5 MHz IQ Panel 2 Plus and other 319.5 MHz systems.

Note: A replacement transformer is available here.
