CMB-1 Clock Module
The CMB-1 Clock Calendar Module is a master clock
module which calibrates all system clocks (i.e. MC-
5000 Keypads) on power up and from then on, every
hour. While typically powered by the ADA Bus, the
CMB-1 also features a battery backup to maintain time
during power outages. The CMB-1 will permit the MC-
6000, MC-5000, MC-3000 OD, and/or MC-3800 OD
keypads to display the date and time when a room is
off. In order for these keypads to display the time,
a single CMB-1 needs to be connected to an open
ADA Bus jack on any wire harness.
The CMB-1 features DIP switches which set the
Baud Rate (baud rates are either 1200 or 19200
and must match the settings of the Suite 16 Sys-
tem, typically 19200), the time mode (12 hour or
24 hour used only during test and setup mode),
Day Light Savings Time On or Off (US DST), and
a test mode. As the CMB-1 features a calendar it
is capable of changing the from Standard Time to
Day Light Savings Time automatically. Only one
CMB-1 is used per system.
If it is preferable for some
rooms to have the
keypad’s display turn off
rather than continuously
display room status or
time, these keypads can
be individually set to blank
out (Blanking On/Off), per-
mitting others to display
status or date/time. Date/
time are displayed only
when the room is off or the
entire system is off.
If the CMB-1 battery is
dead and the system suf-
fers a power loss, the key-
pads will display CHECK
BATT/TIME after all con-
trols have been updated.
This display will continue
every hour until the clock
has been set.
