alarm initiating input signals. “Pre-signal” input is activated by pushing in,
then pulling down the dual action handle. A “General” alarm input signal can
be manually activated via a momentary rocker switch mounted inside the unit.
This general alarm switch can only be a cces sed by opening the cover with the
supplie d key/lock. These pullstationsare UL listed and meet the ADA
requirement of a 5lb. maximum pull force to activate.
Operating instructions are molded in to the handle along with Braille text.
Molded terminal numbers can be found adjacent to the wiring terminals.

Wiring Instructions
Before wiring the pull station, pull all necessary wiring through a mounted backbox and the optional trim ring.
- Using the built – in strip gauge, on the back of the pull station, remove the correct amount of wire insulation.
- Connect the wiring from the FACPs Initiating Device Circuit (IDC), identified as pre-signal, to terminals | and 2 on the pull stations terminal strip. Connect the next pre-signal device on the IDC or an End-of-Line Resistor (ELR) to terminals | and 2.
- Connect the wiring from the FACPs IDC, identified a s general alarm, to terminals 3 and 4 on the pull stations terminal strip. Connect the next general alarm device on the IDC or an ELR to terminals 3 and4.
Warning: Do not loop wiring under any terminals. Break wire run to maintain IDC supervision.
Operation
To activate the pull station, push in and pull down on the handle. The word
‘ACTIVATED?’ appears after the handle is pulled down. This will remain until
the pull station is reset.
The pull station includes two individual Single Pole, Single Throw (SPST)
Normally Open (N/O) switches, one for pre-signal (toggle) and one for general
alarm momentary closed rocker type) a s illustrated below. Activating the
pull station places the toggle switch (pre-signal) into the closed position.
The responsible individual on site would then investigate and if no emergency
exists, the pull station is reset. If an emergency does exist, the pull
station would be opened with the key and the general alarm switch would be
pushed, latching the fire alarm system into alarm, turning on the notification
