The PS561 Voice Dialer Security Console integrates up to 16 security sensors with your X10 home automation system. When the alarm is tripped the console will dial up to four preprogrammed numbers and allow the party on the other end to listen in. This suffers, of course, from the fact that the mic is in the same package as two peizo sirens.
This model is the predecessor to the SC9000 which is much prettier and includes a touch tone security and X10 module control dial-in menu. Modules advertised for either system are compatible with any X10 console, even the new versions of the door/window sensors:
As you can see, the DS12A is much smaller (and therefore sexier) however the integrated magnetic sensor makes placement less versatile. The new sensors take an additional magnetic sensor through the terminals at the bottom so up to two doors or windows can be monitored with one device. This does not, however, provide exactly the same functionality as the DS10A's external sensor as the internal sensor must be bypassed if only the external one is to be used.
You may find yourself forced to install these switches upside down on left-to-right opening vectors such as patio doors. This would be fine if the X10 logo wasn't printed on the front.
The glass break sensors (GB10A) use an adhesive backing to stick right on your window panes. Though they can apparently detect a window breaking within 20 feet to reduce the potential for false alarms I have installed them on every pane of glass (two per window) and put them on their lowest sensitivity.
All of these modules are installed by sliding the console's switch from the RUN1 or RUN2 positions to the INSTALL position then pressing the TEST button and, when finished installing all devices, returning the console's switch to RUN1 or RUN2.
When the alarm is tripped the console sends alternating ON/OFF commands to the house and device code you have configured. The original purpose of this was to flash the outside lights to make your house easier for law enforcement/security to identify but some clever duck realized this signal could also be used to set off remote alarms. The PowerHorn (SH10A) is a module that screws into an outlet anywhere in your home and blasts its four peizo sirens much louder than the security console on its own. If you have a large dwelling space multiple units liberally to ensure a traumatic experience for intruders. The only drawback to these sirens is they are prone to false positives; if you remotely turn on and off the lights associated with their house and device code four times quickly they will go off momentarily which can be quite undesirable at some hours.
Last but not least, of course, the KR10A security keyfob. The lights on/off buttons control the lights on the address the console has been configured for so you can, for example, turn on the outside lights when you exit your vehicle. I haven't had any false positives with the panic feature yet but it should be noted that the cover over the buttons dimples and wears out quickly.
