INTRODUCTION The Securitron Dual Sense Bar (Model DSB) is an exit device intended for use on magnetically locked, non-fire rated doors only.
Fasteners for metal doors (aluminum frame and hollow steel) are included. For through door mounting please call Securitron for a no-charge DSB-TDM kit. Note that US standard or metric fasteners are supplied depending on the version of the bar which was ordered. (The metric version part number for a DSB series bar will include the suffix “M”). 5. RECOMMENDED TOOLS Bubble Level Hammer Center Punch Wrenches: 1/2” Box-end (or Adjustable Wrench) Drill Bits: 3/8” [9.5mm], 11/16” [17.
The bar is level. The bar is centered on the door (left to right) between the door frame stops. By using the assembled bar as a template, the correct separation between the mounting holes will automatically be maintained. After marking the hole locations, verify that the centers of the holes are at the required distance as shown in Figure 4. Figure 3 Figure 4 Page 3 PN# 500-22700 Rev.
6.2. HOLLOW METAL DOOR PREPARATION The bar should be mounted to the door using the blind nuts and screws provided as shown in Figure 6. Use the following step-by-step instructions and Figure 5 for the installation of the blind nuts: a. Drill the four (4) 3/8” [9.5mm] diameter holes through the interior (mounting) surface of the door at the previously marked hole locations. DO NOT drill completely through the door. b. Insert one blind nut assembled to the installation tool into a mounting hole. c.
.4. BOLT THROUGH DOOR PREPARATION: For through-bolt mounting on various door types a DSB-TDM kit will be required (see Figure 7). This product accessory is furnished separately and can be ordered from the factory at no charge. This configuration may be used on solid wood doors, hollow or solid metal doors, or chalk filled *fire doors. Please follow instructions included with the DSB-TDM kit for proper installation.
e. Insert each end of the (spiral) conduit into the recess of each of the cord caps and mount each cap to the door and frame using a Phillips screwdriver and two (2) #6 X 3/4” long pan head screws provided. Figure 8 IT IS SUGGESTED THAT WIRE ROUTING FROM A SOLID DOOR USING THE TRADITIONAL WIRING METHOD BE DONE USING AN ELECTRICAL TRANSFER HINGE OR PIVOT (EPT OR EPTL) WHICH WILL SERVE TO ROUTE THE WIRING FROM THE DOOR TO THE FRAME IN A CONCEALED MANNER.
i. Mark the bar to indicate the desired cut. Note: For a DSB with the illuminated sign option, the bar should always be cut on the end that houses the main (TS) PC board. This will be the end opposite the LED light strip. j. Using a saw, cut the bar to the desired length. Note: It is highly recommended that the cutting of the bar be performed by a band or cut-off saw to produce a neat, straight, clean edge. However, with care, a hacksaw can be used. k.
8. ELECTRICAL CONNECTIONS AND WIRING 8.1. DSB WIRING The DSB is supplied with either a 16-foot [4.88 meter] long cable with traditional wire leads or an ElectroLynx wiring harness. Either of these wiring devices may be used to connect power to the main PC board of the DSB.
Figure 12 – Double Door (No Access Control Unit) Fail secure electric locks are normally not permitted for use with the DSB on required exit applications. Normally open contacts, however, are available for special signaling applications and for integration with the Request to Exit (REX) function of an access control installation.
Figure 15 shows the installation of an MOV in parallel with the magnetic lock. An MOV is provided with each DSB. It is a black (or blue) disk-like component with two bare wires for connection. The MOV acts to suppress the inductive kickback by a lock, which if left unsuppressed will greatly shorten the life of the relay contacts. The MOV has no polarity, but in order to function properly it should be spliced in to the wiring as close to the electric lock as possible.
Figure 16 This product was designed for use with Securitron Magnalocks. The Magnalock secures the door with magnetic force only and therefore has no possibility of jamming and thereby denying egress. The Magnalock also has internal electronics which allow it to release very rapidly. When used with the DSB, which is also a fast device, exit is immediate and the impression a person exiting gets is that the door is not locked at all.
Make sure that the bar is installed with the plastic washers under the head of the mounting screws. Make sure there are no foreign objects or material creating a conductive path from the bar to the door (e.g. metal blinds, etc.). Make sure the bar is free to move and not stuck in the “exit” position. There should be 1/32” clearance at each end of the bar between the end cap and mount flange. See Section 6.2.
Spring Plunger Housing Screws - Loosen and leave in place through holes! PC Board End Mount Base Riser 4. Using a #1 Phillips screwdriver, back out the two (2) screws to release the base riser from the rest of the end mount assembly. NOTE: These screws should remain in place (in the holes of the spring plunger housing and end mount) – This will help keep the plunger housing in place for time of reassembly.

If the PC board/plunger ever become dislodged from the end mount assembly: Reinstall spring and plunger into the housing. Align PC board into slotted rails of end mount.
