Installation instructions for the GE/Sentrol Power Supervision Module, models 204-6V and 204-12/24V.
Installation instructions for the GE / Sentrol Power Supervision Module — models 204-6V and 204-12/24V — which monitors the health of an electrical device's power supply and reports a supervisory fault to a connected alarm control panel if that power is lost.
The Power Supervision Module is wired in series with an end-of-line device to supervise the operating voltage of a connected electrical device (such as a card access controller, electric door strike, or other 12/24V accessory). If power to the supervised device is interrupted, the module's contact opens and the alarm panel's initiating circuit reports a trouble/supervisory condition. Two versions are available depending on the supervised device's operating voltage range.
| Model | Operating Voltage | Operating Current | Contact Rating (resistive) |
|---|---|---|---|
| 204-6V | 5.1 – 15 VDC | 33 mA @ 6 VDC; 66 mA @ 12 VDC | 2A @ 26 VDC or 115 VAC |
| 204-12/24V | 8.5 – 33 VDC | 14 mA @ 12 VDC; 28 mA @ 24 VDC | 2A @ 26 VDC or 115 VAC |
