Alarm Outputs Information

Sentinel UL150 models include a self-diagnostic circuit for monitoring charge fail fault conditions (AC supply/fuse failure, DC fuse failure or low/no charge current), with a solid-state relay output for driving a remote alarm or fault annunciator. Enclosed NFPA models have NFPA 110 compliant alarms for AC failure, charge fail, high battery volts and low battery volts.

Standard Output Calibration

Output Calibration Information

Calibration figures shown are at 20 ºC. If temperature compensation is enabled and remote SNTL-RTC temperature sensor is connected, output voltage automatically varies by 3 mV per cell per 1 ºC deviation from 20 ºC, within the range -10 to 50 ºC. Increasing temperatures give decreasing outputs; decreasing temperatures give increasing outputs.

Features

Features

AutoBoost provides a temporary increase in output voltage, equalizing the charge between cells and maximizing battery life and capacity. AutoBoost is triggered automatically when the battery falls below a preset voltage or can be initiated manually through a momentary switch input. At the end of the AutoBoost cycle, Sentinel automatically reverts to normal float charge mode, preventing battery over-charge and gassing.

Temperature Compensation

Temperature Compensation

The optimum charge voltage for lead acid and NiCd batteries varies with ambient temperature. Sentinel can be configured to sense battery temperature from a remote sensor and automatically compensate the output charge voltage.

Installation and Connection

Installation and Connection

UL-recognized SNTLUL150 model uses an open frame circuit board and base/heatsink with protected cover, for surface or DIN rail mounting in an existing control panel. UL-listed ESNTLUL150 models use a stainless steel, wall-mounted case.

Electrical connection is by screw terminal blocks. Connection and cable access on ESNTL models is by a hinged front plate and knock-out sections in the enclosure side.
