Be the first to review this product

This DSC Alexor 2-Way Wireless Alarm Kit with Vanishing Contact & GSM is a completely wireless alarm system that not only eliminates complicated hardwired installations, but it comes with a set of powerful accessories to ensure that your home is safe and secure against intruders. Included is (1) wireless control panel, (1) 2-way LCD keypad, (1) indoor siren, (1) PIR pet-immune motion detector, (3) vanishing door contacts, and even (1) keyfob for controlling your system from a distance. One such add-on to the KIT495-17GCP01 that sets it apart from the similar KIT495-17CP01 is the internal GSM (Global System for Mobile communication) module. This module enables the system to report and communicate, not only with landline phones, but with cell phones as well. Therefore, if your telephone lines are cut or disabled the home stays secure and there remains a way for the system to call a monitoring station, or you, or both.

Greater Protection. Complete Security
How would you like to offer your customers a security system that The Alexor provides complete security via a host of devices, including keypads, sirens, detectors ,wireless keys - all of it wirelessly? DSC's 2-Way Wireless Security Suite delivers just that…and so much more.

The Power of Speed with Wireless Installation
The Alexor Wireless Panel is the center component of DSC's 2-Way Wireless Home Security Suite. Because it operates completely wirelessly, installers have fewer holes to drill and fewer wires to pull. The system - with its full complement of exclusively compatible wireless accessories, detectors and keypads - takes far less time to install than traditional wired or hybrid systems. Less installation time is a benefit to Home Owners and Installers. Wireless installation means less waiting around and minimal compromise to the home structure.

Security Without Compromise
Alexor is a wireless control panel, the virtual "brain" of the security suite. Because it is a distributed system, the panel is not attached to the keypad physically, but rather wirelessly. Designed for flexible, secure installation locations within the home, as long as there is access to AC power, Alexor operates via up to four wire-free keypads (the WT5500). If the system changes its armed state or a wireless device is tampered with, Alexor will immediately be signaled and the appropriate transmission will instantly be transmitted to the monitoring station, if being monitored. And because the signals between Alexor Wireless Panel and its wireless peripherals are fully encrypted,communication between all devices is exceptionally secure. The Alexor offers all the reliability of traditional wired/hybrid control panels but with all the convenience that wireless delivers.

. Wireless Device Enrollment & Template Programming Further Simplify Installation DSC's installation processes and programming help to further reduce the installer's time at each job. The wireless device enrollment process ensures that installers no longer need to manually program serial numbers or wireless attributes. Instead, a series of enrollment screens prompt installers to confirm Electronic Serial Numbers (ESN), zone numbers and zone type. Template programming allows installers to quickly program the functions required for basic operation by entering a 4-digit code. Code prompts exist for predefined zone definitions, reporting code formats, communication call directions, and DLS setup.
