Silent Knight ECS-INT50W — intelligent 50 W internal amplifier for IFP ECS voice evacuation panels.
An add-on amplifier board that mounts inside the panel cabinet and is powered and supervised by the panel, so it needs no separate AC source or battery. It takes the voice bus from the ECS-VCM or ECS-NVCM.
- 50 W on one speaker circuit at 25 Vrms or 70.7 Vrms; Class B (15 kΩ EOL) or Class A
- 24 VDC from a panel NAC programmed as constant auxiliary power, or a UL-certified auxiliary supply
- Standby 52 mA; amplifier alarm 275 mA at 25 V, 310 mA at 70.7 V; full load 2.84 A at 25 V, 2.9 A at 70.7 V
- Six-wire link (voice bus, SBUS, 24 VDC); DIP-switch SBUS address, not found by JumpStart autoprogramming
- Fits IFP-300ECS and IFP-2000ECS cabinets; IFP-2100ECS, or a cabinet holding an ECS-NVCM, needs the ECS-AMPMT kit
- 4.5 × 10 × 1.81 in.; UL 864 10th Ed. and UL 2572 2nd Ed.
Do not confuse it with the Silent Knight EVS-INT50W, the 50 W internal board for the 6820EVS. The ECS-AMPMT mounting kit is sold separately.
