  • Encrypted S-Line sensor technology protects signals sent to the IQ Panel while still providing support for legacy 319.5 systems
  • Supports up to ten two wire smoke detectors
  • LED lighted zones for ease of “learn-in” installation/troubleshooting
  • EOL supervision using 4.7K Ohm resistors (included) or 1k-10k Ohm depending on Resistor Mode
  • Up to 500 Milliamps of power for hardwired motion detectors, glass break detector, and/or sirens
  • Charging circuit for back-up battery, fully supervised with power outage recovery

The IQ Hardwire 16-F (Small Enclosure) offers a cost effective way of integrating hardwired security & smoke detector zones with the IQ Panel 2/2+. It includes a small enclosure designed to be mounted in an existing can, backup battery charging, 500mA of 12volt auxiliary power, an onboard siren relay, built-in status LED’s for each zone and support for up to 10 two-wire smoke detectors. Normally Open and Normally Closed contacts are supported as well as powered zones like motion sensors and glass break detectors.

Turn your legacy alarm system into a modern connected home

There’s nothing wrong with your existing alarm system. Instead of completely replacing it, use the sensors and siren with your moden IQ Panel.

Trigger home automation

Your wired sensors can be used for home automation. Automatically turn on the lights when a door opens. Or record a video clip. Adjust the thermostat when a door or window was left open.

Detect intrusions and fire with Surety

If you’re going to use a wireless security alarm, choose professional grade hardware with secure wireless communication so you can be confident it will do it’s job.

Why should I use encrypted wireless communication?

The majority of security systems are not as secure as they could be. With technology advancing rapidly, it’s becoming more and more likely that someone who wants to compromise your security system can do so without much effort or expense.

IQ encrypted sensors send signals in a coded form that can only be understood by the alarm system they are connected to. This ensures that only your system can access the content of the message, keeping your sensor activity data safe and practically eliminating your system’s exposure to spoofing and replay attacks.

Don’t worry, this device integrates seamlessly

Surety is your connection to the award winning Alarm.com ecosystem, allowing you to use hundreds of best-in-class security and home automation devices from a single app that runs on almost anything. All that and the industry’s best customer service are why Surety is your home’s best friend.

Do I need to use EOL resistors?
Yes, each zone requires a 4.7K Ohm EOL resistor. (included)
Will it work with my wired siren?
The IQ Hardwire has a dry contact output that can be used to apply 12VDC auxiliary power to a piezo siren. If your siren is a piezo then it should work. Some sirens are just speakers and require an oscillating signal in order to produce sound. If you just have a speaker then you will either need to add a speaker driver (usually a piezo oscillator) or replace it with a piezo siren.
