E-270 Single Action Pull Station
Installation Sheet
Operation
This E-270 Single Action Pull Station combines a single action
pull station with a single input analog addressable mini module
mounted on the back of the unit. The pull station requires a
single action (i.e., pulling the 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 handled is pulled, 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 E-270 provides two status LEDs. The LEDs are visible
from the back of the E-270.

Installation
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

no user-serviceable parts and should not be disassembled.

Module addresses are limited by the control panel
capacity.
