4.39 Zone Status Messages (ZB)
You can send a query to the control panel for its zone status (open, closed, trouble, alert,
bypassed). The control panel will respond with a Zone Status or Zone Partition Status message
for all 208 zones.
In addition, the control panel can be programmed with Global Programming Location 30 to
automatically send zone status messages whenever there is a change of status.
4.39.1 Zone Bypass Request (zb)
This command allows for bypassing/unbypassing a zone. Zone = 000 will
unbypass all burglar zones in the. Zone = 999 will bypass all violated burglar zones.
Area to bypass/unbypass is required if Zone equals 000 or 999 otherwise it is ignored.
10 – Length as ASCII hex
zb – Request zone bypass
ZZZ – Zone number
A – Area to change bypass in if zone = 000 or 999, otherwise not
referenced.
C[6] – Pin Code array valid in the area that the zone is valid in.
This is an array of 6 ascii digits. Array index 0 is the
most significant digit and array index 5 is the least
significant digit of the PIN Code.
00 – future use
CC – Checksum
Example: 10zb0051003456006B Request zone bypass/unbypass
toggle. Area 1. Bypass zone 5 with user code 003456

0A – Length as ASCII hex
ZB – Returned Bypassed Zone Command
ZZZ – Zone number
N – Zone bypass state. ‘0’ = unbypassed, ‘1’ = bypassed
00 – future use
CC – Checksum
Example:
0AZB123100CC Returned value = zone 123 is bypassed.
