Alarm Controls System Accessories - 450 Push Button Switch

The 450 is a flush mount button that drops into a 5/8 inch hole. If you are not drilling into an existing plate or panel, Alarm Controls offers the RP-100 single gang wall plate so the button can be self-mounted at a standard gang box.

No. The 450's contacts are rated .5A at 35 VDC, which is a low-current signal rating. Run it to a relay, access control panel, or timer input and let that device switch the lock power. Wiring a maglock or strike load straight through the button exceeds the contact rating.

Momentary action. The contacts change state only while the button is held and return as soon as you release, which is what a request-to-exit or door release input expects. If you need a button that latches on until pressed again, the 450 is the wrong part.

The Alarm Controls 450 is a flush ivory momentary action push button that mounts in a 5/8 inch hole, with contacts rated .5A at 35 VDC. The Dortronics 5215-SPB is a 1-1/2 inch square illuminated push button supplied on a single gang plate. So the 450 is a small round flush button you drop into a drilled hole in an existing plate or panel, while the 5215-SPB arrives as a complete gang-plate assembly with an illuminated square actuator. If the opening needs a lit button visible in a dark corridor, the Dortronics is the one that offers illumination; if you are adding a discreet release to an existing faceplate, the 450 is the smaller footprint.

The Alarm Controls 450 by itself is a flush switch that mounts in a 5/8 inch hole, so it needs a plate to sit in; Alarm Controls offers the RP-100 single gang wall plate for self-mounting it. If you would rather order a button already built onto its plate, the Dortronics 5215-SPB is supplied as a 1-1/2 inch square illuminated push button on a single gang plate, which removes the separate plate step on the jobsite.

Both. The 450 is sold as a single button, and the 450(25) is a pack of 25 of the same switch. For a multi-door rollout or a stocking van, the 25 pack is the same device in quantity, not a different model.

The button itself mounts in a 5/8 inch hole, so if there is no existing hole prepped, add the RP-100 single gang wall plate and a gang box. You will also need the relay, timer, or controller that the .5A / 35 VDC contacts trigger, since the button does not carry lock current.

Not a drop-in in the literal sense. The 450 is a flush momentary button sized for a 5/8 inch hole, while the Dortronics 5215-SPB is a 1-1/2 inch square illuminated button on a single gang plate, so it replaces the whole plate rather than seating in the same drilled hole. Electrically both are momentary exit release buttons feeding a door control circuit, so the wiring intent carries over, but confirm your circuit suits the 450's contact rating of .5A at 35 VDC before mixing devices on the same run.

The Alarm Controls 450 is offered both as a single switch and as the 450(25) pack of 25 push button switches, which is the practical way to stock one button type across many doors in a facility. Each is the same flush ivory momentary switch mounting in a 5/8 inch hole. The comparable Dortronics 5215-SPB is a single gang plate illuminated button assembly, so if the standard you want is an illuminated square button rather than a flush round one, that is the different device to spec.

Ivory. It is a flush ivory button, so it blends with ivory or off-white plates and panels. On a job standardized to white or stainless trim, the ivory face will read as a slight mismatch, so budget for a plate that suits or pick a button in the finish you are matching.

It is classified as a commercial device, and it is a low-voltage access control accessory rather than a line-voltage light switch. Typical use is a door release or request-to-exit button feeding a controller, relay, or timer.
