Model 4720 Control/Communicator Installation Manual (P/N 150476, Rev. A) Revised 10/98
3.14 Model 4720 Terminal Strip Description
* Note 1: Terminal 4 (16 V) will be at 20 V under normal standby conditions (non-alarm).
* Note 2: Each device connected to Terminal 5 or 10 must be rated for the voltage ranges specified. The minimum
voltage occurs when AC power is off and the battery is discharging under load. The maximum voltage
occurs when AC power is on and the output is not loaded.
* Note 3: The total current drain of Terminal 5, Terminal 10, all touchpads, and all XBUS expansion devices, must
not exceed 1.35 A (see Table 4.1.1.0a).
* Note 4: See Section 3.3.1 for an explanation of PolySwitch protection.
UL note: Refer to wiring diagram on the unit for ratings/connections.
