144 MS-5UD/MS-10UD Series PN 52626:B 8/01/2008
Notes:
1. Reference the 411UD Manual for additional information
2. Program the 411UD for slave operation
3. The MS-5UD/MS-10UD must be programmed for AC Loss Reporting Delay This prevents
the immediate transmission of a trouble on the loss of AC power
4. All connections between the control panel and the 411UD must be in conduit, less than 20
feet (610 cm) in length, in the same room
5. Any zone of the 411UD can be wired to function as alarm, trouble or supervisory. In Figure
B.1 on page 143, Channel 1/Zone 1 is wired to the control panel’s alarm relay, Channel 2/
Zone 2 is wired to the control panel’s trouble relay and Channel 3/Zone 3 is wired to the
control panel’s supervisory relay
6. Nonresettable 24 VDC power is supplied to the 411UD via TB9 terminals configured for
nonresettable power on the FACP. Jumper J4 on the 411UD must be removed for 24 VDC
power
7. End-of-Line resistors must terminate all 411UD circuits, including unused circuits
8. A -VDC from the 411UD Trouble Contacts will activate the Trouble Input J6 on the FACP
