Overview

2.2Specifications

(The black and white circles with numbers indicate the specific panel terminal.)

Voltage Input	Primary:	16.5 VAC 40 VA class 2 plug-in
(Power Supply)		transformer (D1640)
	Secondary:	Sealed lead-acid rechargeable (12
		VDC, 7 Ah or 12 VDC, 17.2 or
		18 Ah) battery. The panel
		supports a maximum of two 12
		VDC, 7 Ah batteries using the
		D122 Dual Battery Harness or
		two D1218 (12 VDC, 17.2 or 18
		Ah) batteries using a D122.
Current Requirements	Panel : 500 mA alarm, 200 mA idle
	See Section 4.1 Current Rating Chart for Standby Battery Calculations in the D7212G
	Approved Applications Compliance Guide (P/N: 4998138560) for the current draw
	requirements of other system components.
Power Outputs	All external connections are inherently power-limited except battery terminals.
	Continuous Power	1.4 A maximum at 10.2 VDC to
	Outputs	13.9 VDC (continuous supply)
		total for all devices and outputs
		supplied at Terminals 3 and 32
		and at the Programming
		Connector.
	Alarm Power	2.0 A maximum at 10.2 VDC to
	Output	13.9 VDC output. Output may
		be steady or one of three pulsed
		patterns depending on
		programming. See Relays in the
		D7212G Program Entry Guide
		(P/N: 4998138538).
	Switched Aux Power	1.4 A maximum at 10.2 VDC to
		13.9 VDC output. Continuous
		output is interrupted by Sensor
		Reset or alarm verification
		depending on programming. See
		Relays in the D7212G Program
		Entry Guide (P/N: 4998138538).
	Fire and	To comply with UL 985 listing standard for fire alarm systems
	Fire/Burglary	(effective March 1, 1989), the total combined continuous and
	Systems	alarm current draw for the system during alarm conditions
		must be limited to 1.4 A (1400 mA) 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 (see
		Figure 17 on page 54).
Minimum Operating	10.2 VDC
Voltage
SDI Bus	SDI Bus A (+):	9 VDC (15000 ft. [4572 m] max.)
	SDI Bus B (-):	9 VDC (15000 ft. [4572 m] max.)
