FX-278 Double Action Pull
Station Installation Sheet
Operation
This FX-278 Double Action Pull Station combines a dual action pull
station with a single input analog addressable mini module mounted on
the back of the unit. The pull station requires two actions by the user to
initiate an alarm. First, to access the alarm handle, raise the upper
door marked LIFT THEN PULL HANDLE. Second, pull the alarm
handle to initiate an alarm.
The device address is set using the two rotary switches located on the
back of the mini module. One device address is required.
The mini module is configured for alarm latching operation. When the
manual station is activated, an alarm signal is sent to the control panel
and the alarm condition is latched at the pull station. The pull station
must be manually reset prior to resetting the panel.
LEDs
The FX-278 provides two status LEDs. The LEDs are visible from the
back of the FX-278.

Installation
Install and wire this device in accordance with applicable national and
local codes, ordinances, and regulations.
WARNING: This pull station does not operate without electrical power.
As fires frequently cause power interruption, discuss further
safeguards with the local fire protection specialist.
Note: The pull station is shipped from the factory complete with a
single input mini module attached. The module contains no user-
serviceable parts and should not be disassembled.
To install the pull station:
1. To meet the Americans with Disabilities Act (ADA), mount the
electrical box 48 inches max. from the floor and attach the pull
station using screws provided with the electrical box.
2. Set the module address. Refer to the panel technical reference
manual for a list of valid addresses.
Use a screwdriver to adjust the two rotary switches on the front of
the module. Set the TENS rotary switch (0 through 12) for the 10s
and 100s digit and the ONES rotary switch for the 0 through 9
digit. For example: device address 21, set TENS rotary switch to 2
and set the ONES rotary switch to 1 (see Figure 2).
3. Verify that all field wiring is free of opens, shorts, and ground faults
before connecting to the module terminals.
4. Make all wiring connections to the terminal block discussed in
“Wiring” and shown in Figure 4.
5. Open the pull station by using a slotted screwdriver to twist the
cover release screw counterclockwise while pulling the cover away
from its backplate.
6. Mount the pull station in the electrical box.
7. If use of the glass rod is desired, pull the glass rod release lever
and install the glass rod through the mounting bracket on the front
of the pull station.
8. Set the toggle switch to the NORMAL position and snap the cover
into its locked position.
