Commercial Fire Requirements
For commercial fire installations, the primary fire keypad must be installed on panel Keypad Port 2 and mounted within
20 feet of the control panel. External wiring must be run in conduit.
Additionally, you can install supplemental fire keypads and devices on ECP Port 1, using an ECP Isolator to separate all
fire wiring from all burglary wiring (see Figure 3-8).

Addressing the Keypads
The keypads will not operate until they are physically addressed and enabled in the system's Device Programming
in the #93 Menu Mode.
Set each keypad for an individual address (00-30) according to the keypad's instructions. Set an alpha keypad for
address 00 and other keypads for higher addresses (00 and 01 are enabled in the system's default program). Any
keypads set for address 02 and above will appear blank until they are enabled in the system's program. Each keypad
must be set for a different address.
• Do not set any keypads to address 31 (nonaddressable mode). They will interfere with other keypads (as well as
other devices) connected to the keypad terminals.
• If an “OPEN CIRCUIT”
message is present on a keypad, data from the control is not reaching the keypad. Please
check your wiring.
