Notifier UDACT

General
UDACT Instruction Manual PN 50050:H 09/16/2002 71
Appendix B: AFP-200
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.
Mounting
Since the AFP-200 cannot accommodate the UDACT in the control panel enclosure, the UDACT must
be mounted remotely using an ABS-8R 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.
Wiring
CAUTION: Remove all power from the control panel by disconnecting AC and batteries before
making any connections to prevent personal and/or circuit damage.
Connections
Refer to Figure 17 on page 72.
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.
Notes:
1. Ferrite cores, PN 29090, are recommended for all applications.
2. Recommended wire is 12 AWG (3.25mm
2
) to 18 AWG (0.75mm
2
) 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 17.
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.
3. Conduit is recommended for external wire runs. Consult local building codes.
4. Refer to "Specifications" on page 13 for power requirements.
