Silent Knight SKE-450 — 50 watt single-channel voice evacuation control with a built-in digital message repeater.
The SKE-450 is not a fire alarm control panel; it is supervised and activated by a host FACP. A reverse-polarity trip on CMD1 plays message 1 and a short across CMD2 plays message 2, so an existing panel gains voice evacuation without replacing the head end. Its single supervised speaker NAC delivers 50 W at 25 Vrms, or 70.7 Vrms with the SKE-V70 module.
- Output: one speaker NAC, 50 W at 25 Vrms (70.7 Vrms with SKE-V70)
- Supervised Class B (Style Y) or Class A (Style Z)
- AC input: 120 Vrms, 60 Hz, 1.2 A (specify 230 Vrms/50 Hz at order)
- Current draw: 140 mA standby, 590 mA alarm
- Battery charging 27.4 VDC at 1.9 A max; 18 Ah max in cabinet
- UL 864 and UL 1711 certified
This SKU is the single-channel base panel. For 4 or 6 speaker zones order SKE-450-ZN4 or SKE-450-ZN6; the SKE-V70 converter and SKE-SRM remote microphone are separate parts.

FAQ
Is the SKE-450 a fire alarm control panel?
No. It is a voice evacuation control activated by one of two alarm inputs from a host panel: a reverse polarity input and a supervised dry contact input.
How many messages does it store?
Three. Messages one and two are built in, up to 30 seconds each; message three is field programmable and can be up to 45 seconds.
Can it run 70.7 V speakers?
Yes, with the SKE-V70 module, which converts the speaker circuit from 25 to 70.7 Vrms.
How do I add speaker zones?
The SKE-ZN4 splitter gives four Class B or Class A outputs and the SKE-ZN6 gives six, both with paging by zone or all call. The total is 50 W for the whole system.
