Application Dimensions The BPS provides additional power and circuits for notification ap- pliances and other 24 Vdc loads. It is listed for indoor dry locations and can easily be installed where needed. y 0 O O Top View Fault conditions are indicated on the on-board diagnostic LEDs, opening the BPS input sense circuit and the trouble relay(if 14-D2 Ii D3 ►1 programmed).While this provides indication to the host system, the BPS can still be activated upon command.A separate AC �� lirFail contact is available on the BPS circuit board, which can be 04—D4�0 programmed for trouble or AC Fail.There are seven on-board .diagnostic LEDs: one for each NAC fault, one for battery fault, one a) Front View Ofor ground fault, and one for AC power. a> —The unique dual-input activation circuits of the BPS can be acti- vated by any voltage from 6 to 45 VDC(filtered-regulated)or 11 D1 0 D6 to 33 Vdc(full-wave rectified, unfiltered).The first input circuit canObe configured to activate 1-4 of the four possible outputs.The to second input circuit can be configured to control circuits 3 and 4. All knockouts mWhen outputs are configured for auxiliary operation,these circuits for 3/4 in conduitcan be configured to stay on or automatically deactivate 30 sec- ° (1.9 cm) o 5onds after AC power is lost.This feature makes these circuits ideal ofor door holder applications.The BPS also has a separate 200 mA 24 Vdc output that can be used to power internal activation �■ 1 111111111161 modules. BPS NACs can be configured for a 3-3-3 temporal or continuous D1 D2 D3 D4 D5 D6 output.This makes the BPS ideal for applications requiring signal- 17.0 in 3.5 in 13.0 in 6.5 in 3.375 in 12.0 in ing rates that are not available from the main system. (43.2 cm) (8.9 cm) (33.0 cm) (16.5 cm) (8.6 cm) (30.4 cm) In addition to the internally generated signal rates,the BPS can also be configured to follow the coded signal rate of the main system NACs.This allows for the seamless expansion of existing Wire routing Power-limited NACs. wiring area The BPS enclosure has mounting brackets for up to three Signa- ture modules to the right of the circuit board.
