    I've seen it mentioned a few times in this group that the 2-piece design
    of the GE Allegro has the advantage that destruction of the keypad
    doesn't prevent an alarm signal from being transmitted. The GE Allegro
    brochure makes this point too. In theory, this sounds nice, as it avoids
    the cost of a remote keypad.

    But looking at how it is implemented, I'm not sure I follow how it
    accomplishes this. From what I've read, the main keypanel is powered
    from an AC transformer, and has the connection point for the hardwired
    zone. It presumably also contains the RF transceiver that is monitoring
    the sensors.

    On the other hand, the dialer (DTIM) is battery powered, and is
    monitored for failure by the main keypanel every 60 minutes. I didn't
    see anything suggesting that the DTIM receives triggers from the alarm
    sensors.

    So it seems the only way this would work as described is if the DTIM is
    programmed to send an alarm notification within seconds of loosing
    communication with the main keypanel. That seems highly prone to false
    alarms.

  2. The Allegro Key pad has a tamper on the unit.

    OK, thanks. That makes sense. So then the question is, will the baseball
    bat kill the controller before the tamper switch is tripped? :)

    Still seems a bit fragile.

    I think a lot of alarm pros still prefer the alarm panel locked in a metal
    box hidden from plain view.
