68 UDACT Instruction Manual — P/N 50050:M 12/18/2009
Appendix B: AFP-200 (UL 8th)
B.1 General
The UDACT is capable of reporting a maximum of 99 zones when used with the AFP-200.
For more information on the AFP-200 see the AFP-200 Instruction Manual.
B.2 Mounting
Since the AFP-200 cannot accommodate the UDACT in the control panel enclosure, the UDACT
must be mounted remotely using an ABS-8RB or UBS-1 enclosure placed within 6000 feet (1828.8
meters) of the control panel. Refer to "Remote Installation" on page 22 for installation instructions.
B.3 Wiring
B.3.1 Connections
Refer to Figure B.1 on page 69.
Connect the communication line between the EIA-485 terminal block TB5 on the AFP-200 and
TB-1 terminals 3 and 4 on the UDACT, being certain to observe polarity.
If last device or no other devices are connected to the EIA-485, install a 120 ohm EOL resistor
(PN 71244) across UDACT TB1 terminals 3 and 4.
Connect the Ground Wire (PN 71073, provided) from the UDACT earth terminal on TB3 to a solid
building earth ground.
Connect 24VDC filtered, non-resettable power from terminal block TB1 on the AFP-200 to TB1
terminals 1 and 2 on the UDACT.
B.3.2 Notes
1. Ferrite cores, PN 29090, are recommended for all applications.
2. Recommended wire is 12 AWG (3.25mm2) to 18 AWG (0.75mm2) twisted pair, shielded
cable. Connect only one end of shield: a) shield may be connected to cabinet (earth ground) at
fire alarm panel, or b) shield may be connected to TB1 Terminal 5 (Shield) at UDACT as
shown in Figure B.1.
3. Conduit is recommended for external wire runs. Consult local building codes.
4. Refer to "Specifications" on page 13 for power requirements.
!
CAUTION: Remove all power from the control panel by disconnecting AC and batteries before
making any connections to prevent personal and/or circuit damage.
NOTE: The shield end that is not connected should be insulated to prevent accidental grounding.
Do not connect both ends of shield under any circumstance since a ground fault may result.
