Bosch DIS240 Remote Test and Indicator Plate

The Bosch DIS240 is used with the DS240 or DS241 Long-Range Beam Smoke Detectors and the DS290 Series Duct Smoke Detector Housings. This Bosch DIS240 plate has LEDs to indicate the detector’s status, test points to read signal voltage, and a key-operated test switch to test and reset the detector.

Use the operating key to turn the switch to the TEST position to activate a fire alarm. Turn the switch “to RESET” to reset the detectors and silence the alarm. The DS240 or DS241 detector or the DS290 Series housing requires eight conductors. Use 18 AWG wires or larger. Mount the Bosch DIS240 no more than 100 ft from the detector or duct housing. Mount the DIS240 on a standard double wire-mold box.

Connect a standard volt-ohm meter (VOM) to the DIS240 voltage monitor plugs to check the DS240 or DS241 and DS290 Series sensitivity level after installation. The voltage measurement decreases as the signal level approaches alarm.
