Simplex 4010-9823 — 240 V expansion power supply for the 4010 fire alarm control panel, adding 4 A of notification power.
Simplex instructions 574-057 pair two part numbers: 4010-9813 is the 120 V supply and 4010-9823 the 240 V one, so this is the 240 V mains variant, not the usual North American item. The board sits in its own slot to the right of the 4010 SFI/O module and gives a maximum of 4 A of filtered, power-limited 24 VDC, split across NAC circuit 3, NAC circuit 4 and two AUX taps on TB1, no circuit drawing more than 2 A. The SFI/O board supervises both AUX taps and the battery connection, raising a trouble if either falls below 18.26 V.
- 4 A maximum filtered 24 VDC, power limited and battery backed
- Only one expansion supply is allowed per 4010 system
- AC harness 733-955 for this 240 V supply; the 120 V supply takes 733-949
- Mounts with the supplied slotted Torx screws 441-002
- Expansion Power must be switched ON in the panel CFIG before it reads normal
Confirm the mains voltage first: the 120 V sibling is 4010-9813, and the two are not interchangeable. This is the supply board, not the AC harness or a battery harness.
