4007ES and 4007ES Hybrid Fire Alarm Systems Installation Manual
5.1 Power supply specifications
The IDNAC Power Supply can supply 4A of 24V power in addition to the base draw of the CPU/power supply cards. The current draw taken from
optional cards, IDNet Devices, Aux Power, and NACs must be subtracted from 4A.
Table 13: 4007ES system current draw
Maximum AC input
2 A at 120 VAC, 50/60 Hz
1 A at 240 VAC, 50/60 Hz
Standby conditions (see Note 1) Current (see Note 1) (Battery Standby 24 V)
No alarms (NACs normal). No IDNet devices connected 180 mA
Add to above for each additional IDNet or IDNAC device in standby 0.8 mA
Total current for fully loaded IDNet or IDNAC channel in standby 431 mA
Alarm conditions (see Note 1) Current (see Note 1) (Battery Alarm 24 V)
IDNAC ON: No IDNet LED On. No IDNet devices connected 185 mA
Add to above for each IDNet device in alarm (see note 2) 1 mA
Add to above for each IDNet LED On (20 maximum IDNet devices LEDs On) 2 mA
Total current for fully loaded IDNet channel in alarm (20 LEDs On) (see note 2) 475 mA
NOTE:
1. Add an additional 9 mA per active auxiliary relay (Alarm or Standby).
2. The IDNAC Alarm current depends on the IDNAC device used. See the relevant device manual for more information on currents.
5.2 IDNAC section overview
The IDNAC power supply has a single SLC for connecting addressable IDNAC devices. The power supply is compatible with TrueAlertES and TrueAlert
Addressable product lines, both multi and fixed candela. The IDNAC output is Class B only. Class A operation requires use of the optional module
4007-9804, IDNAC dual Class A isolator.
The output is duplicated on the terminal block to facilitate T-tapping on the circuit at the panel. EOL resistors are not required.
All wiring is supervised and power-limited.
