It's a hell of a lot more that 25 signals.

16 bytes for CID format transmitted twice is 32 bytes
32 x 8 = 256 bits
25kb / 256b = 97.6 signals/mo.


Communication Protocol:
18 SSSS QXYZ GG CCC K
18 = Uniquely identifies this format to the receiver and
to an automation system, but not displayed on the
printer
SSSS = 4 digit Subscriber ID
Q = Event qualifier, which gives specific event
information
E = 1 New event or opening
R = 3 New restore or closing
P = 6 Previous event
YXZ = Event code (3 Hex digits)
GG = Group number (physical or logical, 2 Hex digits)
CCC = Zone or sensor number(3Hex digits, event
reports) or user number (Open/close report)
Note: The GG and CCC fields can contain 0 for a null (no information) field.
