NEGATIVE ONLY
Connect rechargeable lead acid type battery’s negative terminal (-) to Terminal
4. (See the Current Rating Charts section in the panel’s Approved Applications
Compliance Guide to determine battery size requirements.)
5 (+)
BATTERY
POSITIVE ONLY
Connect rechargeable lead acid type battery’s positive terminal (+). (See the
Current Rating Charts section in the panel’s Approved Applications Compliance
Guide to determine battery size requirements.)
6 (+)
+ STEADY OR
PULSED ALARM
POWER
Supplies up to 2 A at 10.2 VDC to 13.9 VDC for steady or pulsed alarm output.
Use Terminal 9 for common. Programmed as Relay A. Shares PTC with
Terminals 7 and 8.
7 (+)
+ ALTERNATE
ALARM POWER
Supplies up to 2 A at 10.2 VDC to 13.9 VDC for steady or pulsed alarm output.
Use Terminal 9 for common. Programmed as Relay B. Shares PTC with
Terminals 6 and 8.
D136 Plug-in Relay required: Install a D136 in the ALT ALARM socket for
output at Terminal 7.
8 (+)
+ SWITCHED
AUX POWER
Supplies up to 1.4 A at 10.2 VDC to 13.9 VDC. Use Terminal 9 for common.

23 (-)
ZONEX
COMMON
24 (+) ZONEX POWER +
[D9412G only] Use Terminals 23 and 24 to power ZONEX modules such as
the
D8125 POPEX module, the D8128D OctoPOPIT, and the D8129 OctoRelay.
Shares PTC with Terminal 3.
25 ZONEX IN 2
26 ZONEX OUT 2
[D9412G only] Connect ZONEX modules for Points 129 to 247 and Relays
65 to 128 to these terminals.
27 ZONEX IN 1
28 ZONEX OUT 1
Connect ZONEX modules for Points 9 to 127 and Relays 1 to 64 to these
terminals. (The D7412G uses Points 9 to 75, the D7212G uses Points 9 to 40.)
29 (-) COMMON Common terminal for SDI devices.
30 DATA BUS B
31 DATA BUS A
Terminals 30 and 31 are a two-wire bus that drives the command centers,
printer interface, and access control modules including the D9133TTL-E
Ethernet Interface Module, D9133DC Direct Connect Module, D9133 Serial
Interface Module, and the PC9133TTL-E Ethernet Interface Module.
32 (+) POWER +
Power for SDI devices. Shorts on any other terminal do not affect this separate,
protected power output for SDI devices.
