D7212G

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.)
