3.9 Zeta Zone Relay Module (ZZRM) Operation
Up to four ZZRMs may be connected in series to the ZRM port in the lower left-hand corner of the
board. A ZZRM module contains five relays that may be programmed individually as system
relays. The relays are automatically assigned addresses on loop zero. The first ZZRM occupies
addresses 10 – 14 (0:10 – 0:14), the second, addresses 15 – 19, and so on.
Two steps are needed to make sure that the panel will recognize any ZZRMs. First, the panel must
be told how many ZZRMs will be connected to the panel. Refer to section 4.2.5.2 for programming
instructions. Second, pins 1 and 2 on the ZZRM furthest from the CP3 must be jumpered. If any
module but the furthest ZZRM is jumpered across pins 1 and 2, the panel will see only as far as
that ZZRM. All other ZZRMs should be jumpered across pins 2 and 3. Refer to section 2.7.1-a for
installation diagram.
3.10 Zeta Serial and Isolated Communication Ports (ZSCP3 / ZICP) Operation
An RS-232 communication port may be added to the panel to provide a way to talk to a printer. The
small board attaches to J9 and J2 of the panel, just above the ZRM port, and connects to the
printer via a DB9 female-to-female cable.*
There are two types of communication ports: Isolated and Serial (Non-Isolated). Note: it is nor-
mal for the panel to report a ground fault when an ZSCP3 is installed and connected to a
printer or PC. The isolation of the ICP will prevent ground faults and is therefore the device recom-
mended by Zeta Alarm Systems. Also, the ZSCP3 / ZICP does not reside on the network and
therefore does not get scanned in. The device is automatically detected by the panel at RESET.
However, the panel can be programmed to print either automatically, or on command. See section
4.2.2.1 for programming directions. Note: the ZSCP3, ZICP use 9600 baud, 8 data bits, 1 stop bit,
no parity.
There are actually several ways to get information from the CP3 to a printer. If an ZSCP3 / ZICP is
not installed, the CP3 prints out the Program Port at J2 using the PCI cable (p/n 3000-6015). If
ZSCP3 / ZICP is installed, data will print through the DB9 connector instead. If any remote printers
are attached to the network via a PNI board, the panel will print through those printers instead of
an ZSCP3 / ZICP or Program Port (J2).
*NOTE: The ZSCP3 requires a Null Modem cable; the ZICP requires a Straight-Through
cable. Both cables must be DB9, Female-to-Female.
