This information describes how to achieve dual switching with one magnetic contact and one magnet. DPDT magnetic contacts such as the Sentrol 1087D, 1084D, 2507AD, or 2707AD (see catalog) may be used in place of two contacts or one contact and a floor mat for an annunciator panel.
You can increase the gap distance of a recessed switch in a door about 40% by placing two magnets side-by-side. This is helpful if you need to increase the gap distance but do not have a wide gap switch.
Each sample was selected at random from finished goods inventory. Tests on each contact were run to measure pull in (make), and drop out (break) distances prior to mounting on the 6" wide, 16" long, and 1/2" thick steel plate.
Sentrol recessed contacts can be installed in a variety of positions to accommodate any application. As shown in Figure 1, the switch and magnet can be mounted end-to-end within an imaginary arc around the switch, or parallel to the switch.
The interior of a boat can be protected with a magnetic contact in a simple alarm system. Protecting the hatches and companionway can be easily accomplished using recessed or small surface mount switches.
Five methods are presented here for protecting deeply recessed doors with surface mount contacts. Note that when mounting on steel, a spacer should be used behind the switch, and/or a wide gap switch should be used.
It may happen, during installation, that holes are over-drilled, under-drilled, or have an uneven diameter. Oversized holes can occur due to difficulties in drilling, especially in tight quarters or enclosed spaces.
Gun cabinets can be protected like china cabinets on the previous two pages. However, since the glass front to a gun cabinet could be broken, and guns stolen without sounding the alarm, two other methods for protecting guns are provided here.
Other chain link fence gates can be protected with magnetic contacts. Brackets attach to gate post and gate frame, depending on diameter of post and gate. Switch or magnet may be mounted on inside, outside or side of bracket, depending on space between post and gate.
The 2515A is equipped with the unique Maxi-Gap feature that allows a vertical gap distance of 6" and an overall side-to-side gap of 6". Use for installing security switch on channel of overhead doors that do not line up properly, sag, or that are loose and move with wind or vibration.
The next generation SafeAir 250-CO carbon monoxide (CO) detector is an accurate and reliable means of alerting building occupants of potentially dangerous levels of CO in the protected area. The internal electro-chemical sensor communicates with a sophisticated on-board microprocessor that accurately tracks CO levels over time.
Edwards brand 500 Series two-wire conventional photoelectric smoke detectors bring together trusted technology and a full line of features that meet the demands of every type of application. The 500 offers sounder models in two-wire applications, specifically to meet residential occupancy code requirements.
Choose Edwards signals to alert, warn and communicate, and you get solutions designed for safety first - because safety is the heart and soul of everything we make and do. With the industry’s broadest line, we have the proven products that can help make your hazardous locations a bit less hazardous. Trust your hazardous location signaling to the life safety leader.
The Edwards family of intelligent components also offers contractors and installers simple setup and installation, while delivering options that take full advantage of intelligent fire alarm processing. With a microprocessor in each device, intelligence is distributed throughout the system so that command decisions are made at the individual module, rather than bottlenecking at the control panel.
Edwards life safety systems are a powerful intelligent solution for small to mid-sized buildings. The Edwards family includes intelligent addressable and conventional fire alarm control systems. A full line of remote annunciators, modules and accessories are available for both intelligent/addressable and conventional panels.
New Kidde KIR Series detectors represent the next generation of detection technology with features that mesh seamlessly with Kidde FX fire alarm systems. These high-performance smoke and heat detectors offer innovations designed to ensure that they will suit the application, remain accurate, and stay fully-functional throughout their service life.
The windows-based MEDI software package provides command and control of remote signaling devices throughout your facility. With a few simple clicks, you can program MEDI to automatically signal work start and stop times, break times, or any other timed event. You can also manually command MEDI to initiate tones, wav files, or real-time voice. Any time. It integrates with either conventional or RS485 signaling components.
Get multi-function power and true flexibility for both emergency and routine signaling. With a single Millennium System Master you take complete control of all your emergency, evacuation, and routine signaling. And you do it with functionality and features that can turn plant-floor signaling into a powerful business tool.
R-Series Annunciators are high-performance remote annunciators that provide status indication and common controls for Edwards Intelligent Addressable fire alarm systems. This family of annunciators offers LCD or LED annunciation as well as a graphic annunciator driver. Models are available with and without common controls.
There is a tremendous need for integrated and supervised emergency evacuation and fire systems. Oversight agencies realize this and have either made or are making code changes. In fact, the Occupational Safety and Health Administration (OSHA) has drafted a regulation specifically to address a facility’s emergency action plan and to allow safe escape of employees from the workplace (OSHA Regulation 1910.165).
Adaptatone Millennium multiple-tone electronic signals offer the widest selection of tones in the industry. With short code blasts or sustained warning signals, they meet virtually every application requirement from emergency evacuation to routine communications.
