1.6 ULC Remote Connection Feature
ULC requires that devices such as TM-4 and UDACT/UDACT-2 be disconnected during annual testing to prevent transmission of false alarms.
Disconnecting TM-4 for Annual Testing: Follow standard installation procedures as described in the TM-4 installation documentation. To disable
reporting, slide SW4 Disable All Output switch from “Enable” to “Disable.” Refer to TM-4 documentation for product drawing.
Disconnecting UDACT/UDACT-2 for Annual Testing: Install UDACT/UDACT-2 as the last device on the EIA-485 line, with a listed key switch
such as AKS-1B installed on the EIA-485 line. In this case only, install the ELR between the EIA-485 wires just in advance of the key switch (refer to
Figure 12). The key switch should be installed so that key-removed is the closed position; it should be located inside the same backbox as the UDACT/
UDACT-2, as close to the UDACT/UDACT-2 as possible.
1.7 Devices Requiring External Power Supervision
With LCM-320 revision 2.0 and higher, certain type codes have external power supervision (FlashScan only) built into the software. An external
power-supervision relay is required (see Figure 13) unless one of the following type codes is selected for the device:
NOTE: During testing when the key switch is turned, the panel will report a communication failure for the UDACT or UDACT-2’s address.
• Control • (Blank) • Nonreset Ctl • Gen Super
• Strobe • Release Ckt • Alarm Pend • Gen Trouble
• Horn • Rel Ckt ULC • Gen Alarm • Gen Pend
• Trouble Pend
