SG-PSU3 Power Supply Unit
The SG-PSU3 is the SG-System III power supply. The SG-System III requires a 120VAC/60Hz input power source. A power cord with a
IEC connector is required. The model SG-System III CE requires a 240VAC, 50Hz
input power source.
NOTE: For UL/ULC installations use only 120VAC/60Hz to power the SG-System III.

For UL installations use UL listed UPS Power Supply for protective signaling systems and/or listed burglar
alarm power supply, as applicable.

The model SG-System III CE is not UL/ULC Listed.
Electrical Specifications:
SG-System III UL
• Input voltage range: 120VAC
• Frequency: 60Hz
• Input current: 2.5A max (RMS) @120VAC
SG-System III CE
• Input voltage range: 240VAC
• Frequency: 60Hz
• Input current: 2.5A max (RMS) @ 240VAC
In a 2-rack configuration, a redundant SG-PSU3 can be inserted in the second shelf. In the event of a SG-PSU3 failure, the redundant SG-
PSU3 automatically assumes operation. These modules are
Hot Swappable (can be removed/replaced while the system is in operation) if a
working redundant SG-PSU3 is installed.
SG-CPM3 Central Processing Module
The SG-CPM3 Central Processing Module collects system information and directs line card information to the appropriate outputs. Along
with its built-in scroll buttons and large LCD message screen, the SG-CPM3 features TCP/IP, parallel printer and two serial RS-232 ports for
computer interface capability. The printer is supervised for loss of power, off-line, paper out and other trouble conditions. The communica-
tion link to the automation computer through the RS-232 and TCP/IP port can be monitored by the supervisory heartbeat transmissions.
Line Cards
The SG-System III supports a maximum of 24 line cards. Each line card is equipped with non-volatile memory to record events. For each
POTS card (SG-DRL3, SG-DRL3E and SG-DRL3-2L), calling source (Caller ID, ANI and calling name) capability is built-in and telephone
numbers can be printed out, sent to automation and stored in memory. Events and information stored in memory may be printed at any time.
The SG-DRL3-2L and SG-DRL3E may perform flash updates over the front edge USB port connection.
The SG-DRL3/SG-DRL3E/SG-DRL3-2L receives ANI (Automatic Number Identification) and/or DNIS (Dialed Number Identification Ser-
vice) via the Telco connection. This information allows the Sur-Gard System III to automatically change profiles for each received call. This
eliminates dedicated line pool hardware. The DNIS information is used in a look-up table, which sets up virtual line pools to identify security
formats and extend account numbers. Standard DNIS is supported up to 10 digits. Each dialed number would have formerly been a line pool
on conventional line cards.
