Figure 3: Wiring Diagram
NOTE: Install external devices connected to Items 10~17 in the same room as the SG-System I. Maintain a 6.5mm (1/4”) sep-
aration between power limited and non-power limited circuits. All circuits are supervised and power limited with the excep-
tion of AC input, which is non-power limited. Maximum cable length is 1.8m (6’). Longer cables may impair performance.
NOTE: F
or ULC Installations
, the equipment must be rack mounted and powered by a permanently wired supply in accor-
dance with C22.1, Canadian Electrical Code, Part 1, Safety Standard for Electrical Installations, section 32. This equipment
is intended to utilize the building emergency AC supply system for its standby supply (UPS, batteries in conjunction with
engine-driven generator). Connection to Building Emergency Power Supply (UPS recommended) with a minimum 24hr
standby capability is required. For UL Listed Installations
, use UL Listed UPS (Uninterrupted Power Supply) for protective
signalling systems and listed burglar alarm power supplies as applicable.

For CE Installations For ULC Installations
Main Supply: 240Vac/50Hz Main Supply: 120Vac/60Hz
UPS Output Rating (non UL): UPS Output Rating:
240Vac/50Hz 120Vac/60Hz
For UL/ULC Installations
Mains Supply: 120VAC/60Hz
UPS Output Rating: 120VAC/60Hz, 2.5A. In the USA, use UL listed UPS (uninterrupted power supply) for protective-signalling systems and
listed burglar alarm power supply as applicable. In Canada, connection to an emergency power supply (UPS) with a minimum of 24 hr standby
capacity is required.
For CE Installations
Mains Supply: 240VAC/50Hz
UPS Output Rating (non UL): 240VAC 50Hz
Warning:
To reduce the risk of electrical shock, the SG-System I is equipped with a grounding-type power supply IEC receptacle. Connect SG -Sys-
tem I using an appropriate IEC cable to a grounded receptacle. Connect SG-System I to UPS dry contact connections only. Do not connect
to a receptacle controlled by a switch.
