FDM-1 DUAL MONITOR MODULE
The FDM-1 Dual Monitor Module is intended for use in in-
telligent, two-wire systems. It provides two independent two-
wire initiating device circuits (IDCs) at two separate, consecu-
tive addresses. It is capable of monitoring normally open
contact fire alarm and supervisory devices; or either normally
open or normally closed security devices. The module has a
single panel-controlled LED. NOTE: The FDM-1 provides two
Class B (Style Y) IDC circuits ONLY. Class A (Style Z) IDC
circuits are NOT supported in any application.
FDM-1 Specifications
Normal operating voltage range: 15 to 32 VDC.
Maximum current draw: 5.7 mA (LED on).
Maximum operating current: 750 µA (LED flashing).
EOL resistance: 47K ohms.
Maximum IDC wiring resistance: 1,500 ohms.
Temperature range: 32° to 120°F (0° to 49°C).
Humidity range: 10% to 93% (non-condensing).
Dimensions: 4.5" (11.43 cm) high x 4" (10.16 cm) wide x
2.125" (5.398 cm) deep.
FDM-1 Automatic Addressing
— The FDM-1 auto-
matically assigns itself to two addressable points, starting
with the original address. For example, if the FDM-1 is set to
address “56”, then it will automatically assign itself to ad-
dresses “56” and “57”. NOTE: “ones” addresses on the FDM-1
are 0, 2, 4, 6, or 8 only. Terminals 6 and 7 use the first ad-
dress, and terminals 8 and 9 use the second address.
Avoid duplicating addresses on the system.

INSTALLATION
FMM-1, FDM-1, and FZM-1 modules mount directly to a stan-
dard 4" (10.16 cm) square, 2.125" (5.398 cm) deep, electrical
box. They may also be mounted to the SMB500 surface-mount
box. Mounting hardware and installation instructions are pro-
vided with each module. All wiring must conform to applicable
local codes, ordinances, and regulations. These modules are
intended for power-limited wiring only.
The FMM-101 module is intended to be wired and mounted
without rigid connections inside a standard electrical box. All
wiring must conform to applicable local codes, ordinances,
and regulations.
