Timed Electronic Shunt - SB-2000 Series

The Timed Electronic Shunt is designed to electronically shunt across a switch or sensor that is being monitored by a normally closed protective loop. It may be set for a 15, 30 or 60 second time delay. The timer may be reset to the initial delay time by depressing the button while the switch is being shunted. The green LED will flash while the switch is shunted. During this time, it is safe to open the switch without going to an alarm condition. If the switch is not closed by the time the LED stops flashing, the system will go into an alarm mode.

The Shunt Switch comes in two versions: a recessed version - SB-2000 designed to fit inside a single gang utility box, and a surface mount version - SB-2001 which may easily be mounted to the wall in an existing structure.

The SB-2000 is powered by an external power supply with optional battery backup.

Surface Mount Version - SB-2001 Series

Remove the Shunt Switch from the surface mount case. A knockout is provided on the back of the case for wire access. Attach the surface mount case directly to the wall, or it may be mounted to cover a single gang electrical box. Attach the door switch wires to terminal TM1 pins 2(-) and 7(+) (See Figure 3). Connect positive side of the control panel to pin 7 and the negative side to pin 2. Using an external 12 volt DC supply, run the wires from the power source to the alarm unit and attach the positive voltage to pin 1 and ground to pin 2 of terminal TM1. If battery backup is desired, connect a standard 9 volt battery to the battery connector. The LED will flash twice during power up, and then a third time 5 seconds later indicating a successful diagnostics test. Lay the battery in the bottom of the case and reassemble the Shunt Switch with the button toward the bottom of the case and the LED toward the top. Secure face plate with the two screws provided.
