Installation Instructions
Momentary Operation
In the Momentary position, even a stuck switch input will allow the door to time out and close, thereby providing security to occupants.
The DS1+ will however still operate normally if one of the other inputs is activated. Essentially, it ignores the faulty activation source as
all inputs are isolated.
Additionally, we provide a direct connection from an apartment interphone panel. Only Relay 1 (strike) will operate when a voltage is
applied to this input. A vestibule courtesy switch will be energized for the set by Pot. 1.
Maintained Operation
Select Relay 1 Maintained for an access control application. When a maintained signal is applied to WET 1 input, the lock will remain
energized, while the DRY 2 input allows a wall switch to open the door.
An input of DRY 1 will always unlock and open the door.
Select Relay 2 maintained if you are connecting the DS1+ to a re alarm panel or to a pressure sensor.
In this mode the lock will re momentarily but the operator relay will be held in as long as the input is maintained.
Latching/Ratchet Operation
In this mode the DS1+ will latch Relay 2 with a momentary activation of Dry/Wet 1. Relay is released when Dry/Wet 1 are activated a
second time. If Dry/Wet 2 are activated, Relay 1 and Relay 2 are latched until Dry/Wet2 are activated again.
Washroom Door Controller
In this mode, complete control of a single occupant barrier-free washroom is obtained. It allows the user to lock and secure the door
from the inside by depressing a Push-to-Lock button. The exterior wall switch is removed electronically from the circuit. To exit the
washroom, simply exit manually via the lever-handle set (the door contact switch resets the relay, or, press the interior wall switch to
unlock and activate the door operator. The door remains unlocked upon closure.
Another feature is the ability to use the DS1+ on “Normally Secure” washrooms. In this mode, the door is usually locked. To gain
access, the user must rst swipe a card, or enter a code into the Access System (i.e. keypad), which then signals the DS1+ to unlock
and open the door. Once inside, the occupant presses the Push-to-Lock button, which removes the exterior wall switch from the circuit.
Exiting may be accomplished manually via the lever-handle set (the door contact switch resets the relay), or, by pressing the interior
switch to unlock and activate the door operator. The door will re-lock upon closure.
Bi-Directional Door Sequencer
In this mode, the relay will sequence two automatic doors, in both directions. Upon a switch closure from one side, a signal is sent to
the rst door (Relay 1) then after an adjustable delay, the second door (Relay 2) receives a signal. When a switch closure is made from
the opposite side, the sequence is reversed – Relay 2 is activated, then after the adjustable delay, relay 1 activates.
When used as a door sequencer the user can select either momentary position for the inputs or maintained position. In the momentary
position, even a stuck switch input will allow the door to time out and close, thereby providing security to occupants.
The DS1+ will however still operate normally if one of the other inputs is activated. Essentially, it ignores the faulty activation source,
as all inputs are isolated. In the maintained position, a switch that is held on will cause its respective relay (operator) to be held on. So,
switch #1 would hold in relay #1 and switch #2 would hold in relay #2.
If an emergency (or anti-entrapment) switch is desired in the vestibule, then wire that switch directly to one of the operator inputs.
Usually the exterior door is used in this case.
IMPORTANT: Do not apply power until you have read the instructions fully and made the required adjustments.
