The mobile systems, MCS and MD series do not require any installation or assembly. The unit arrives on it's castors and just needs to be plugged into a standard wall outlet in order to keep the batteries charged.
The the wall mounded hardwire and standalone systems, SSH, SHCS, SACS series do have some assemply and installation requirements. These models ship palletized with the cabinet separated in 2 or 3 parts. The lower battery compartments need to be attached to the upper cabinet with 4 fasteners. Then the entire assembly gets mounted to the wall. Once the battery backup system is fastened to the wall, the batteries will need to be installed. Installation of the batteries is much like installing car batteries.
Hardwire systems are usally installed by a local electrical contractor, who also connects the utility input and output wiring.
The standalone plug and play systems do not require a licenced contractor to install.
Battery replacements are recomended every 48 months. If the batteries have never been heavily discharged more than once, they weaken which makes them unable to put out their full capacity.
If the batteries have been weakend in any way or no longer can put out their rated capacity they should be replaced.
The hardwire system is intended to get connected into the building wiring. The input gets fed from the main electric panel and the systems output breaker directly feed various outlet branch circuit, equipment and lights that is intended to have backup support.
Installation cost of the Hardwire System can vary with local contractors rates and level of dificulty to install and intergrate it in with the building's wiring. If the system is being installed during new construction, the install can cost a lot less than reconfigueration with the wiring of an existing office.
The standalone SACS and SSA systems do not require building circuit wiring so the installation costs can run a lot less.
It is impossabile to ansewer this question, without knowing exactly what equipment or applliances are to be allocated with backup support, . Medi-Products systems are customizable to suit each and every application in order to meet the desired runtime and requirments of the particular user.
If the application is for an operating room, 2 hours is the standard backup support runtime requirement. Lifesafety codes for egress and exit lighting requirement is 90 mins.
For an application such as a vaccine refrigerator or freezer, the runtime is suited to the comsumers choice. Battery support runtimes are often configured to accommodate runtimes anywhere from 2 hours up to 30 hours.
Both 120 and 220 volt input and output voltages are available. This varies with the model number. If the building only has 208 volts - a 3 phase, a transfromer may be required to boost the voltage from 208 to 120/240.
Each system is custom built to the customers spec. Our standard lead time is 2 weeks plus transit. However leadtimes can vary with production levels so it is always good to ask what the current leadtime is at the time of ordering.
The mobile systems are shipped and delivered "white glove". We use moving van line companies to transport these systems. The reason for this is they ship completely assempled and are too heavy to remove from the pallet all in one piece, resulting in damaged goods. This service always offers a team of 2 with a lift gate to transport the system directly from the truck to it's storage location.
The Silent Sentry wall mounted battery backup systems are knocked down in 2-3 pieces with the batteries boxed up seprately from the cabinet these systems will arrive pallitized. These system must me wall attached prior to battery installation.
This depends on the size of the system and the circut that is connected to. Unless it is otherwise specified each system it is configured with a standard 15 amp plug for charging the batteries. Some of the larger systems where higher amerage and/or voltages are nessessary. Such systems are fed with twistlock plugs of which the plug NEMA number is specified on the order.
The Silent Sentry wall mounted systems can be configured to be surface mounted or recessed between 2 wall studs. The configuration should be specified at the time of order.
The system has an internal transfer switch which automatically transfers to battery power when the input power loss is detected. This occurs within a fraction of a second.
These battery backup systems can supply power to more that one refrigerator or freezer. The system would have to be sized to accommodate the sum of all the appliances of which it is intended to support.
Medi-Products does not manufacturer a 3 phase power system but we do have access to suppliers who do. Three phase battery backup systems have to be designed, engineered and installed properly, this is normally done by the manufacturer or an electrical engineering firm.
All of our emergency power systems are custom built and assembled using only UL approved componants and to nationally reconized standards. There are times however when the completed system in it's entirety has to be inspected and approved by a national standards testing lab. Medi-Products has a lot of experience working with these agencies and special inspection labels can be accommodated upon request.
For certain models an optional remote system monitoring is available via an internet connection. This option will allow the users to remotely monitor battery voltages, and system status.
Medi-Products battery backup systems come with a low battery alarm which makes an audioable sound when the batteries drop below a certain voltage.
The VRLA storage batteries we use contain very little electrolite. Here is a link to the Material Safety Data Sheet: https://www.mediproducts.net/hubfs/CSB%20HRL%20Series%20%20msds-1.pdf for the batteries we use.
For the mobile systems there are 3 cart sizes available. The purpose of this is to accommodate more backup battery capacity. There are many varations within each cart size therefore pricing in not reflected by the size, of the cart but rather by the capacity of the system.
Yes, over the years our company has sold may systems to Canada. We have also met the CSA regulations to do so may be reshipped from a CSA laboratory. The systems are priced and sold in US dollars.
The ansewer is yes. It is not common but our moble systems can be configured for hardwire applications. This is often done while replacing another out of date system in an existing medical pracitce. To do so we configure the mobile system with male and female twistlock cord caps, so the system can connect into the building wiring thru twistlock recipticals.
The heat output varies on the conditions and mode of which the unit is operating under. These are some estimates of heat dissipation of dynamic values based on some specific extreme conditions of which the power system would be operating under:
|Full Load - Rated Wattage||660 W||2250|
|0 Watts||25 W||85|
|@ Full Bulk Charge Mode||425 W||1450|
