The BAPI BA/ROM, VOM, COM, and RYOM Wireless System Output Modules are specifically designed to connect to any BA/RCV receiver and communicate over an RS485 communication trunk to generate standard output signals for any BAS system. A total of 127 modules may be interspersed on the RS485 trunk. Each will output a signal representative of its assigned remotely located wireless transmitter. Each module may be powered from the receiver power bus, or individually, based on overall system power requirements. The BAPI BA/ROM Thermistor Simulation Output Module converts a wireless transmitter temperature signal according to a standard thermistor curve. The two standard curves are 10 KΩ Type 3 and a 10 KΩ Type 2, with a resistance temperature response of 35° to 120°F (1° to 50°C). The BAPI BA/VOM Voltage Output Module converts a wireless transmitter temperature signal to a standard voltage signal. The two standard voltage outputs are 0-5 VDC and 0-10 VDC, with voltage temperature responses based on individual models. The BAPI BA/COM Current Output Module converts a wireless transmitter temperature signal to a standard 4-20 mA current signal. The 4-20 mA current is typical of a loop powered (9-36 VDC) device with current temperature responses based on individual models. The BAPI BA/RYOM Digital Output Module converts the pushbutton on a wireless room temperature transmitter to a solid-state relay closure for AC or DC voltages (5 second momentary actuation). NO or NC solid-state contacts are available, based on individual models. The BAPI BA/RYOL Digital Output Module converts the BA/WDI digital input tranmitter signal to a latching relay output. NO or NC contacts are available, based on individual models. The BAPI BA/SOM Setpoint Output Module converts the setpoint data from a wireless receiver to a resistance or voltage output.
