How Many Wireless Zones Are On a DSC Impassa?

There are 64 wireless zones on a DSC Impassa. Any sensor that is used with the Impassa System will require at least one of these zones. The system has a built-in wireless receiver that supports the legacy DSC 433 MHz Sensors. Any sensor that operates at a different frequency won't work.

An alarm system interfaces with wireless sensors by accepting their incoming wireless signals. This is done using a wireless receiver. For wireless all-in-one systems like the DSC Impassa, a wireless receiver is generally built into the panel. The integrated wireless receiver will determine which type of wireless sensor frequency will work with the system. For the DSC Impassa, the system will support 64 different wireless zones, with the sensors operating at the 433 MHz frequency. Legacy DSC Sensors operate at this frequency.

Every wireless sensor requires at least one wireless zone to work with an alarm system. Some sensors may use multiple zones. For instance, a door contact might use one zone to operate as a contact, while also using a second zone to function as a wireless transmitter for a normally closed hardwired device. Whether or not a sensor needs multiple zones depends on its functionality.

Since the wireless receiver for the DSC Impassa accepts the 433 MHz frequency, sensors that do not operate at this frequency cannot be used with the system unless a wireless to wireless converter, such as the Resolution Products RE524X is used. For example, Honeywell 5800 Series Sensors operate at 345 MHz, so they won't work. The same goes for 2GIG (345 MHz), Qolsys (319.5 MHz), Interlogix/GE (319.5 MHz) and DSC PowerG (915 MHz).

And remember, only a maximum of 64 wireless zones can be used with the system at any given time. If you try to exceed this number, the system will not support additional sensors. Hardwired sensors that communicate with the system using a wireless transmitter or a wired to wireless converter also count towards this limit so keep that in mind as well.
