Table 26: Specifications

Voltage Input	Primary:	Terminals 1	16.5 VAC 40 VA class 2 plug-in transformer (D1640)
(Power		and 2
Supply)	Secondary:	Terminals 4	Sealed lead-acid rechargeable battery (12.0 VDC, 7 Ah or 12.0 VDC, 17.2 or 18
		and 5	Ah). The control panel supports up to two 12.0 VDC, 7 Ah batteries using the
			D122 Dual Battery Harness or two D1218 (12.0 VDC, 17.2 or 18 Ah) batteries
			using a D122.
Current	Control Panel: Idle 225 mA; Alarm 300 mA
Requirements	Refer to the Current Rating Chart for Standby Battery Calculations section in the D9412GV3/D7412GV3 Approved
	Applications Compliance Guide (P/N: F01U143069) for the current draw requirements of other system components.
Power	All external connections are power-limited except battery terminals.
Outputs*
	Continuous	Terminals 3,	1.4 A maximum at 12.0 VDC nominal (continuous supply) total for all devices and
	Power	24, and 32	outputs supplied at Terminals 3, 24, and 32 and at the accessory and
	Outputs		programming connectors.
	Alarm Power	Terminals 6	2.0 A maximum at 12.0 VDC nominal output. Output can be steady or one of
	Output	and 7	three pulsed patterns depending on programming. Refer to Relays in the
			D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807).
	Switched Aux	Terminal 8	1.4 A maximum at 12.0 VDC nominal output. Continuous output is interrupted by
	Power		Sensor Reset or alarm verification depending on programming. Refer to Relays
			in the D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807).
	Fire and	To comply with	UL 985 and 864 listing standards for fire alarm systems (effective March 1, 1989),
	Fire/Burglary	the total combined continuous and alarm current draw for the system during alarm conditions must
	Systems	be limited to 1.4 A provided by the primary power supply (rectified AC). If current draw for the
		system exceeds 1.4 A, remove connected devices until the current draw falls below 1.4 A. Then,
		connect the removed devices to a D8132 Battery Charger Module or to an external power supply
		(refer to Figure 29 on page 58).

*For UL 864 applications, refer to Table 3 on page 11 for compatible devices.
