Alarm Controls TS-9 5/8" x 7/8" Green Button, "PUSH TO EXIT", DPDT Momentary, Narrow Plate

The Alarm Controls TS-9 is a request to exit (REX) push button station mounted on a narrow 1-3/4-inch 302 stainless steel wall plate  a 5/8-inch by 7/8-inch green rectangular illuminated push button labeled "PUSH TO EXIT" with a DPDT momentary action switch. If you searched "alarm controls ts-9 wiring diagram", "ts o9", "alarm controls ts-9", "ts 9", or "timer for 9:58"  this is the product.

"Timer for 9:58" and "TS O9": What These Searches Mean

"Timer for 9:58"  The product dimensions are 5/8 inch by 7/8 inch. When those dimensions appear on a spec sheet, a search bar, or a label, the sequence "5/8 x 7/8" is sometimes misread or typed as "9:58"  the digits 5, 8, and 9 rearranged in a time format. If you searched "timer for 9:58" looking for an Alarm Controls product, this is the TS-9 push-to-exit button. It is not a timer  it is a momentary push button switch. The TS-9T variant does have a built-in adjustable timer relay (covered below).

"TS O9"  This is a typed or OCR variant of "TS-09" or "TS-9". The letter O and the number 0 are frequently confused in print and scan contexts. TS O9, TS09, TS-9, and TS 9 all reference the same Alarm Controls narrow plate push-to-exit station.

What the TS-9 Does: REX in Plain Language

The TS-9 is a request to exit (REX) station  a momentary push button mounted on the secure side of a door that signals the access control system to release the electric lock, allowing the person inside to exit without a credential. The button press sends a dry contact signal through the DPDT switch to the access control panel, which then briefly unlocks the door.

REX buttons are used on electric strike doors, maglocked doors, and any electrified opening where the inside egress requires a signal to the lock rather than a mechanical handle operation. The TS-9 is the narrow plate version  it mounts in a 1-3/4-inch wide space, correct for narrow door frames, aluminum storefront stiles, and tight corridor walls where a standard single-gang plate will not fit.

TS-9 Wiring Diagram: How the DPDT Output Connects

This is the most-searched functional detail on the TS-9 and the gap on every competitor page. Here is the wiring connection.

The TS-9 ships with 10-inch colored leads. You need to understand what DPDT means to wire it correctly. DPDT  Double Pole Double Throw  means the switch has two separate sets of contacts (two poles), each with a common (COM), normally open (NO), and normally closed (NC) terminal. On button press, COM connects to NO. At rest, COM connects to NC.

LED power leads: Connect the LED+ and LED- (or the two power-designated leads) to your 12V or 24V power supply  AC or DC both work. This powers the green illuminated button. The LED operates on 12 or 24 VAC/VDC.

Signal leads  DPDT main contacts (3A, 35VDC / 120VAC): For a fail-safe electric strike or maglock, wire the COM and NC contacts in series with your lock power circuit. At rest (no button pressed), COM-NC is closed  power flows continuously to the lock, holding it locked. When the button is pressed, COM-NC opens  power to the lock is interrupted, the lock releases. This is the standard REX wiring for a fail-safe lock.

For an access control panel REX input, wire COM and NO to the panel's REX terminal. At rest, COM-NO is open. Button press closes COM-NO, sending the signal to the panel. The panel then releases the lock on its own circuit.

Timed output (SPDT, 2A, 35VDC)  TS-9T variant only: The timed output SPDT contacts are a second set that activates for the timed period after button press. These are separate from the main momentary DPDT contacts and are rated 2A at 35VDC.

TS-9 vs TS-9T vs TS-9L: The Three Variants

Every competitor page lists these variants but none explains the functional difference between them:

TS-9 (this listing): Momentary DPDT  contacts close only while button is physically depressed and return to rest state immediately on release. Standard REX for access control panels that manage their own unlock timing internally.

TS-9T  With adjustable timer relay: The button press activates both the momentary DPDT contacts and a timed relay output. The timed relay holds for an adjustable period of 2 to 45 seconds after the button press  the door stays unlocked for the timer duration even after the button is released. Use TS-9T when the access control system does not have its own unlock timer or when a specific held-open duration is required at the device itself.

TS-9L  With latching action switch: Latching means the switch toggles on first press and stays in that state until pressed again. Press once  switch latches closed. Press again  switch opens. Used in applications requiring sustained lock release without holding the button, such as passage mode or long-access-period management.

TS-9 vs TS-7: Narrow Plate vs Single Gang

If you need the standard single-gang plate version  Order the TS-7 (same button, same contacts, 430 stainless steel single-gang plate). The TS-9 is the narrow 1-3/4-inch plate version in 302 stainless steel for tight mounting locations. Both have the same 5/8 x 7/8-inch green rectangular button with hi-brightness LED and DPDT momentary contacts.
