Honeywell GSMX Power Output Worksheet
GSMX GSM Communicator – Current Loading Worksheet
Before installing this product, first ensure the system's control panel has enough available power. The best method is to assess all the ECP devices and figure the total current draw. Then subtract that from the control panel's maximum aux power current. This will give you the available power for the GSMX. Follow the simple procedure below to determine if an auxiliary power supply is needed. Step 1 provides some reference information covering the maximum available aux current for popular control panels. If your control panel is not listed here, please refer to its installation guide.

STEP 1 – Determine the Control Panel's Available Power.
Control Panel VISTA-10P VISTA-15P VISTA-20P VISTA-32FBP VISTA-128FBP VISTA-250FBP Maximum Aux Power 500mA 600mA, or 500mA for UL 600mA, or 500mA for UL 1.0A 1.0A 1.0A The GSMX GSM Communicator requires 12VDC @ 200mA.
STEP 2 – Determine the total power for all ECP Devices.
System Devices 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Total Current Draw for all ECP Devices Current Draw
For control panels that do not have enough available power, you must add an aux power supply such as the Honeywell AD12612 Auxiliary Power Supply, 1361 Transformer, and 12V 4Ah backup battery. Note: When using an auxiliary power supply, ensure the negative output of the auxiliary power supply is also connected to the negative Aux Power terminal in the control panel. Refer to the wiring diagram on the reverse side.
STEP 3 – Does the Control Panel need an Aux Power Supply?
YES Install the GSMX.
Subtract the: Total Current Draw for all ECP Devices from the Control Panel's Available Power Is the available power greater than 200mA ? Install an Aux Power Supply for the GSMX.
