Description
The PS-DA pull station is a non-coded, dual-action manual pull station with a key-lock reset
feature. It provides Silent Knight control panels with one normally open (N/O) alarm initi-
ating input. The PS-DA meets the ADAAG controls and operating mechanisms guidelines
(section 4.1.3[13]), and the ADA requirement for a 5 lb. maximum pull force to activate
the pull station. Operating instructions are molded into the pull station handle along with
Braille text. Molded Terminal numbers are also present.
Ratings
Switch contact (N/O) is gold plated for reliability and rated at 0.25 A at 30 volts (AC or DC).
Installation
The PS-DA pull station can be surface mounted to an SB-10 or SB-I/O surface backbox or
semi-flush mounted on a standard single-gang, double-gang or 4˝ (10.16 cm) square electrical
box. The optional BG-TR trim ring can be used if the PS-DA is to be semi-flush mounted.
Operation
To activate the dual-action 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 sta-
tion is reset.
The pull station includes one Single Pole, Single Throw (SPST) Normally Open (N/O)
switch which closes upon activation of the pull station.
Resetting the Pull Station
1. Insert the key into the lock and rotate 1/4 turn counterclockwise.
2. Open the door until the handle returns to normal.
3. Close and lock the door.
NOTE:
Closing the door automatically resets the switch to the ‘Normal’ position. Opening
the door will not activate or deactivate the alarm switch.
CAUTION!
Do not detach the door of the pull station during installation. The door of the pull station
cannot be reattached to the backplate after the backplate has already been installed onto an
electrical box.
