§ 01Overview

What the RSRDM is

The RSRDM Universal Roller Door Reed Switch is a rugged wired magnetic contact made for the doors a normal reed switch cannot handle. It detects whether a roller shutter, garage door or large commercial door is open or closed, and reports it to a zone on a hardwired alarm panel.

It is a normally closed (NC) switch, the configuration most installers prefer because a cut wire or a faulty contact shows the door as open and trips the zone rather than failing silently. The magnet and switch are built into a metal alloy housing with a nickel-plated neodymium magnet, and the contact is fitted with 480 mm stainless-steel armoured leads (22 AWG) so the wiring near the door survives the knocks and movement of a roller door. The wide operating gap (around 50-60 mm) allows for the larger, less precise alignment of shutters and garage doors.

This is a wired device, not a wireless sensor: despite the listing's branding it connects by cable to a panel zone, the same as any standard NC contact, so it works with Bosch and other hardwired or hybrid alarm panels. The switch mounts on the frame and the magnet on the door, aligned so they sit close when the door is closed. It should be installed by a licensed security installer or competent technician familiar with NC alarm-zone wiring.

§ 02Engineering

RSRDM specifications

- Heavy-duty wired reed switch for monitoring roller shutters, garage doors and large commercial doors.

- Normally closed (NC) output, the fault-tolerant choice: a cut wire or faulty contact shows the door as open and trips the zone.

- Wide operating gap (around 50-60 mm) to suit the larger, less precise alignment of roller and garage doors.

- Metal alloy housing with a nickel-plated neodymium magnet for a durable, strong magnetic contact.

- 480 mm stainless-steel armoured leads with 22 AWG wire to protect the cabling at the door against knocks and movement.

- A wired contact (not a wireless device); connects to a zone on any standard hardwired or hybrid alarm panel.

§ 04Why choose this

Built for the way you actually use the RSRDM

Made for big doors

A wide operating gap and heavy-duty housing suit roller shutters and garage doors, where a standard reed switch will not align reliably.

Fault-tolerant NC wiring

The normally closed output means a cut wire or fault shows the door as open and trips the zone, rather than failing silently.

Protected wiring

480 mm stainless-steel armoured leads guard the cable at the door against knocks and the movement of a roller door.

Works with any panel

As a plain wired NC contact it connects to a zone on Bosch and other hardwired or hybrid alarm systems.

§ 05Where it fits

Right at home in these scenarios

Garage doors

Monitor whether a tilt or roller garage door is open or closed as part of a home alarm.

Commercial roller shutters

Secure shopfront and warehouse roller shutters where a wide-gap contact is needed.

Industrial and warehouse doors

Protect large moving doors that a standard surface contact cannot cover.

Hardwired alarm zones

Add a durable open/close input to any wired or hybrid alarm panel zone.

§ 06Setup

Installation & setup

01

What it is

A wired normally closed (NC) roller-door reed switch. It is not a wireless device: it connects by cable to a zone on a standard alarm panel.

02

Mounting

Mount the switch on the door frame and the magnet on the door, aligned so they sit close when the door is closed; the wide gap allows for roller-door movement.

03

Wiring

Wire the NC contact into an alarm panel zone (often in series with other NC contacts). The armoured leads protect the cable near the door.

04

Professional install

Installation should be completed by a licensed security installer or a competent technician familiar with NC alarm-zone wiring.

§ 07Questions

Frequently asked about the RSRDM

Q.01

What is the RSRDM used for?
It is a heavy-duty wired reed switch that monitors whether a roller shutter, garage door or large commercial door is open or closed.
Q.02

Is it a wireless sensor?
No. Despite the branding it is a wired contact: it connects by cable to a zone on a standard hardwired or hybrid alarm panel.
Q.03

Is it normally open or normally closed?
It is normally closed (NC), so a cut wire or fault shows the door as open and trips the zone.
Q.04

What is the operating gap?
It has a wide operating gap, around 50-60 mm (the listing also references up to about 65 mm); confirm alignment on site.
Q.05

Why use it instead of a standard reed switch?
Roller and garage doors move and align less precisely, so they need a wider-gap, heavy-duty contact like this one.
Q.06

What are the leads like?
It has 480 mm stainless-steel armoured leads with 22 AWG wire to protect the cabling at the door.
Q.07

Which panels does it work with?
Any standard hardwired or hybrid alarm panel with a spare zone, including Bosch systems.
Q.08

Who should install it?
A licensed security installer or competent technician familiar with normally closed alarm-zone wiring.

Need a wireless contact instead?

For a cable-free door or window contact, see the RFDW-SM RADION wireless reed switch (needs a RADION receiver).

03

Add motion detection

Pair door monitoring with motion detection such as the wired BDL2-WP12G pet PIR.
