The DSC WS4965 is a triple function sensor that offers options for monitoring a door, window or garage door. It can operate as a standard door and window contact with a magnet, or it can be used as a tilt sensor for monitoring a garage door. It can also be used as a wireless transmitter.
The sensor operates at a wireless frequency of 433 MHz. This makes it compatible with the DSC Impassa, as well as DSC PowerSeries Alarm Systems. There are three possible functions that will work with the device. The function that is performed will depend on its programming settings. These possible functions include operating as a standard door and window contact, as a tilt sensor for garage doors and as a wireless transmitter for hardwired devices.
By default, the device is set to work as a door and window contact. In this mode, the device is placed on a door or window frame. A magnet is then placed on the door or window itself, within a half-inch of the sensor. When the door or window is opened, the magnet will separate from the sensor. The sensor will recognize this and send a signal to the alarm system to let it know that the door or window has been opened. The system will then perform the programmed response for that zone.
Another option is to use the device as a tilt sensor for a garage door. To do this, the sensor will be installed at the top of a garage door from the inside. When the garage door opens, the sensor will shift from a vertical position to a horizontal position. The sensor will recognize this and send a signal to the alarm system to let it know that the garage door has been opened. The system will then perform the programmed response for the wireless zone.
The WS4965 also features two contact inputs. These can be used to support two different normally closed hardwired devices. The normally closed hardwired devices will connect directly with the sensor, and the sensor will send a wireless signal to the panel on the behalf of the devices. This allows the hardwired devices to essentially function as wireless devices.
Other features include a case tamper switch to let the system know if anyone tries to tamper with the device or disable it. An LED light on the front of the device will let the user know when the battery is low and in need of replacing. The device operates using a CR123A lithium battery that can easily be replaced by the end user. The device measures in at 2.9375"L X 1.6875"W X 1"H.
