## Description

Sensaphone External Power Sensor IMS-4840 for IMS-1000 and IMS-4000 Sensaphone External Power Sensor IMS-4840 for Sensaphone IMS-4000 and IMS-1000 systems lets you monitor power anywhere within your infrastructure. It reports any loss of power and measures the current voltage in the circuit, allowing you to know the status of each server rack and even of your remote UPS. Any failed generator starts are reported to you immediately. The IMS-4840 can monitor voltage from 0 - 250VAC 50/60Hz. The Power Sensor connects to the IMS-4000 Host or Node via an RJ-45 cable (e.g. CAT5 cable). Note: FGD sensors, accessories, etc. are not compatible with IMS-4000 systems by Sensaphone. The connection from the sensor to the Host or Node can utilize your existing network wiring infrastructure. For example, the sensor may be installed in another room or another floor. Connect the sensor to your structured wiring network via an RJ-45 jack. At the other end, connect a patch cable from your structured wiring patch panel directly to the Host or Node environment input. IMS External Power Sensor (110/220VAC) IMS-4840 Specifications: Range: 0 to 250 VAC, 50/60 Hz Accuracy: +/- 2% Power Connection: Universal IEC-320 power inlet Housing: Black plastic with mounting ears Compatibility: IMS-4000, IMS-4000 Node, and IMS-1000 Package Contents: (x1) Power Sensor (x2) Plastic drywall anchors (x2) #6 Metal tapping screws (x4) Rubber feet
