Product Description

1.4 Circuits

Input Circuits
Two input IDCs (Initiating Device Circuits) on the SFP-2402 and four IDCs on the SFP-2404
provide Style B (Class B) configurations. All IDCs accept i
wire smoke detectors, four-wire smoke detectors and normally-open contact devices.
Output Circuits
• 24 VDC resettable special application power output - 500 mA
• 24 VDC nonresettable special application power output (SFP-2404 only) - 500 mA
• 24 volt battery charger (up to 18 Amp Hour batteries)
Notification Appliance Circuits
One NAC (Notification Appliance Circuit) Style Y (Class B) on the SFP-2402
Two NACs Style Y (Class B) on the SFP-2404
Relays
Alarm Relay
Trouble Relay (fail-safe)
Supervisory Relay (SFP-2404 only)
Form-C contacts rated 2.0 amps @ 30 VDC (resistive)

1.5 Components

Main Circuit Board
The main circuit board contains the system's CPU, power supply, other primary components and
wiring interface connectors. Optional modules plug in and are mounted to the main circuit board.
Cabinet
The backbox measures 14.5" (36.8 cm) x 15.218" (38.65 cm) x 2.875" (7.3 cm) and provides space
for two batteries (up to 7 Amp Hours). Also included is a dress panel which mounts inside the
cabinet.
Transformer Assembly
One 100VA transformer is provided standard with the FACP. An optional second 100VA
transformer is available for the SFP-2404 to provide maximum accessory power.
Batteries
The cabinet provides space for two 7 Amp Hour batteries (larger batteries up to 18 Amp Hour,
require use of a UL listed battery box such as the BB-17). Batteries must be ordered separately.

1.6 Optional Modules and Accessories

CAC-4 Class A Converter Module (SFP-2404 only)
The CAC-4 Module can be used to convert the Style B (Class B) Initiating Device Circuits to Style
D (Class A) and Style Y (Class B) Notification Appliance Circuits to Style Z (Class A). The
module connects to J1 on the SFP-2404 main circuit board.
4XTM Transmitter Module (SFP-2402 and SFP-2404)
The 4XTM provides a supervised output for local energy municipal box transmitter and alarm and
trouble reverse polarity. It includes a disable switch and disable trouble LED. A module jumper
option allows the reverse polarity circuit to open with a system trouble condition if no alarm
condition exists. The 4XTM mounts to the SFP-2402 main circuit board option module connectors
J3 & J5 or the SFP-2404 main circuit board, occupying one of the two sets of option module
connectors J3 & J5 or J4 & J6.
