Specifications
AC Input Specifications:
Note: Maximum circuit breaker is 20A.
120 V, 50/60 Hz, 4.6 A
220/230/240 V, 50/60 Hz, 2.3 A
DC Output Specifications: 29 V @ 9 A
Up to 5A normal standby (AUX, "Card Power" and Backplane Power). Any non-
alarm current must be subtracted from 9A alarm current.
DC Input
(battery
standby)
Standby – No alarms, SLCs normal: 135 mA / Alarm - 12A @ 24V
With IDNet 2: 235 mA
Per IDNet/IDNAC device: 0.8 mA
Internal
Battery
Charger
Charges up to 50 Ah (ULC-S527) or 115 Ah (UL-864 Listing) sealed lead-acid
batteries connected to the power supply.
High Voltage Output: 29 V
Output Current Limit: 3.3 A
IDNAC SLCs 29.5V maximum @ 3A per circuit; 4,000 bits/second
Earth Fault Earth fault detection is 10k minimum to any circuit.
SNAC wiring
fault Detection
Short circuit detection is 5k ohms maximum for SNAC. Open circuit detection is
15k.
Battery
Standby
(sealed lead-
acid batteries)
Battery standby requirements are dependent on system configuration. The
4100ES can support up to 115 Ah batteries (UL) and 50 Ah batteries (ULC).
With 115 Ah batteries, a system could be configured to draw 3.8A for 24 hours,
followed by 15 minutes at 9.375A. Or a configuration with 0.375A for 24 hours
and 5 minutes alarm at 9.375 would require 12.7 Ah batteries or larger. Refer to
Sales Engineering Calculation Tool for specific configurations.
