3.2.6Request to Enter [RTE], Terminals 11 and 12

Description. When Terminal 11 is momentarily shorted to Terminal 12, the strike is activated and the door point is shunted.

Shunt Only: An option is provided that only shunts the point when this input is momentarily shorted. To activate the shunt, but not the strike, program RTE Shunt Only? as [YES].

3.2.7Request to Exit [REX], Terminals 13 and 12

Description. When Terminal 13 is momentarily shorted to Terminal 12, the strike is activated and the door point is shunted.

Shunt Only: An option is provided that only shunts the point when this input is momentarily shorted. To activate the shunt, but not the strike, program [REX] Shunt Only? as [YES].

REX must not be used for emergency exit applications. NFPA 101 requires that a UL listed panic device be used to provide direct power from the standby power source. (see Figure 2: Wiring Diagram for Typical D9210B Installation, p.15 for wiring an emergency exit device). Check with your local Authority Having Jurisdiction (AHJ) prior to installing your system.

3.2.8Enclosure Tamper Switch, Terminals 8 and 9

Description. A short to this loop will generate a Missing Trouble Point ### for the point number assigned to the D9210B. With this tamper point faulted, the D9210B will still function.

Connect a N/O tamper switch to Terminals 8 and 9. Upon opening the enclosure, the tamper switch will short the inputs and generate the Missing Trouble Point ### message.

SDI FAILURE ### and MISSING PT ### are reported to the central station when the SDI bus has failed or the D9210B is missing.
