GE Allegro

[Tom Metro]

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.

The Allegro Key pad has a tamper on the unit.

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.
