The 670, 770, and 771 keypads also provide an optional

Emergency, or Fire report to the central station. The user
just presses and holds two top row Select keys for two
seconds until a beep from the keypad is heard.
At the beep, the panel sends the following zone alarm
reports to the central station: Panic (left two Select keys) -
Zone 19, non-medical Emergency (center Select keys) -
Zone 29, and Fire (right two Select keys) - Zone 39.For
1912XRpanels, version 111 orhigher firmware isrequired
