Qolsys IQ Fob vs IQ Fob-S
The only real difference between the Qolsys IQ Fob-S and the standard IQ Fob is that the IQ Fob-S includes built-in "S-Line encryption". The two keyfobs also have slightly different designs. Otherwise, the two devices operate in the same manner, providing the same functions and features.
The IQ Fob-S uses rolling code encryption when speaking with the panel. Whenever the IQ Fob-S sends a command to the panel, it must share a uniquely encrypted code. The command will only successfully go through if this encrypted code is supplied. The encrypted algorithm between the IQ Fob-S and the system at the time of enrollment.
Meanwhile, the standard IQ Fob only uses one-way communication when interacting with the security panel. It does not take any proactive protection measures whatsoever when sending a signal. This makes the IQ Fob considerably less secure than the IQ-Fob-S. Users should take this into consideration if they decide to use an older IQ Fob with their Qolsys security system.
Although the designs for the two keyfobs vary slightly, they both offer a look that resembles a simple car remote. This makes both keyfobs safe to use in a potentially dangerous situation. Both designs can easily fit into your pocket, and their attached metal rings makes adding these keyfobs to your keyring a simple process.
Other than the contrasting encryption methods and the differing designs, the IQ Fob-S and the IQ Fob are basically the same. They will both work at a range of up to 100 feet away from the security panel. Both keyfobs can be used to arm and disarm the panel, and they can both send a panic signal by pressing and holding the lock and unlock buttons at the same time. Additionally, both the IQ Fob-S and the IQ Fob will function with both the Qolsys IQ Panel 2 and the original Qolsys IQ Panel. However, it will only use encryption with the IQ Panel 2. Finally, the processes for programming the IQ Fob-S and programming the IQ Fob follow the same steps on the security panel.
