Specifications
2.0 Overview
Voltage Input*
(Power Supply)
Primary:
16.5 VAC 40 VA class 2 plug-in transformer (D1640)
Secondary:
Sealed lead-acid rechargeable battery (12 VDC, 7 Ah or 12 VDC, 17.2 or
18 Ah). 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 D9412G/D7412G Approved
Applications Compliance Guide
for the current draw requirements of other system components.
Power Outputs*
All external connections are inherently power-limited except battery terminals.
Continuous
Power Outputs
1.4 A maximum at 10.2 VDC to 13.9 VDC (continuous supply) total for all
devices and outputs supplied at Terminals 3, 24, and 32 and at the
Accessory and Programming Connectors.
Alarm Power
Output
2.0 A maximum at 10.2 VDC to 13.9 VDC output. Output may be steady or
one of three pulsed patterns depending on programming. See Relays in the
D9412G/D7412G Program Entry Guide
.
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 D9412G/D7412G Program Entry Guide.
Fire and
Fire/Burglary
Systems
To comply with UL 985 and 864 listing standards for fire alarm systems (effective March 1,
1989), the total combined continuous and 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 26).
