Simplifying the Hook-up for Hardware Integration to the Electrified Door

DoorLink’s bring all Electrified Devices to One Connection Point

What is a DoorLink SIP28?

Click on image to enlarge

DoorLink is a circuit board that measures 4” (200mm) x 7.25” (184mm) set up with header pins and sockets and are configured to take plug-in connectors and relays.

The reason for header pins and sockets only on the base is so that the user need only to populate the board to perform the required functional integration requirement.

Features:

12Vdc Default, user Selects 24Vdc

Terminal Connection Pts. In	28
Terminal Connection Pts. Out	28
Link Connectors	17
Relay Sockets (12Vdc @2A)	4
Inputs to relays - Dry	4
Inputs to relays - Wet	4
Onboard Time Delay 0.05 Sec	1
Plug-in Time Module 1-30 Sec	1

About the Features:

The base configuration responds to 12Vdc and by cutting resistors it can be configured for 24Vdc. The volt setting, if changed, is the same for all operations. Relays can be linked with a wire connection. Volt settings cannot be mixed.

Link connectors enable the user to link terminal points together in groups that either eliminates or reduces wire jumper connections to a

minimum. There are a possible three groups that can be setup and installers often link all the required ground and all the positive terminal points into terminal connector groups.

Terminal connectors are top load with clamp and screw — wire size 22—14 gauge, to 300V. Please don’t think about more than 24V. Relays are 2A and are always 12Vdc DPDT, 24Vdc is accomplished by cutting the designated resistors.

Input configuration makes provision for either a dry contact switch activation or a wet (12/24VDC) contact switch to activate the relay. Only one type configuration can be used for the base board as the inputs are all powered from the board source selected.

The onboard delay time module provides approximately 0.5 (1/2 sec.) between the in and out connections related to the delay. It’s primary role is to provide a short delay between the 1st trigger and a 2nd trigger and comes into play for example when a latch must be released before the Automatic Door Opener can cycle. It can also be used to slow down the door position switch (DPS) reporting to allow a REX signal to be received by the access DCU before the DPS, thus avoiding a false forced open alarm. It is invoked from a trigger of dry or wet contacts closing. This timer is dedicated to relay K4. If the timers are not used the relays are available for other use.

The plug-in time module (TM30) is a separate module that plugs into the circuit board and provides activation time from 1 to 30 seconds set by a POT. It is dedicated to relay K2 and is triggered by a dedicated set of dry contact terminals closing.

How does it work?

Back to the Top

Providing integration services to the portal is always a creative challenge to enable the “Sequence of Operation” necessary to properly organize the electrified application to the users desired functionality, while taking into consideration the building code and site characteristics.

When there is a number of electrified devices located on or at the door for egress or access operations, the quantity of wire and the required interconnections for functionality becomes a real issue to terminate. Where do they occur?

Most installers will use a relay module and/or timer modules to effect the logic to set up the operational devices to function to a given understanding or a documented “Sequence of Operation”.

The SIP28 provides a blank slate with a sequencing timer built-in that will support up to four relays and terminal connectors plus an optional adjustable 1 to 30 second plug-in timer if required.

The simplest setup may only required a minimal quantity of terminal connection points to position an electric strike to work in conjunction with an automatic door opener and the access system. A low-volt power source may also be required.

(I’m a firm believer in that when two trades or providers are coming to the same portal that the integration work should be performed in a

common box designated for the connection work. The portal can then be serviced by both parties without accessing each others proprietary equipment. Making the ADO header the SIP is only an option when the ADO provider is the only provider to the portal integration for electrified operations, even then, in my opinion, it is questionable.)

A more complex application, for example a health care facility, may require retraction system exit devices + magnetic locks + card access + local pull station + magnetic hold-opens + local key control over the holders, all for a pair of corridor doors. A lot of wire to terminate for power and control. The need for relays to defeat the holders when the access system is active and hold the exit devices during non-fire conditions are complex integration issues that need a place and professional applied method to make orderly connections that can be documented.

With the SIP28 the installer only adds the components necessary to the blank board to make the function desired operational.

The outcome is that the installer setup can be configured and tested prior to the site visit as bench work. As a result of the pre-workup a schematic hookup instruction is ready for the actual installation work. The benefit of having multiple trades involved only at one location in the integration process is cost effective for everyone involved.

How much does a SIP cost?

SIP 8” x 8” Enclosure box with SIP28 mounted on the std. insert tray. The box comes with a screw down lid.
The outer row of 8-pin terminal blocks are suggested for external connections coming to the SIP28 board. When external wires are terminated to these connectors the installer can work with the external wiring with the plugs removed. When the connections are complete or modifications are required all external wires are removed without effecting the logic connections already applied to the board for functional operations.

Establishing the actual application cost of connecting the electrified devices, for access/egress control, is dependant on where you consider the beginning or starting point. My experience deals with contract work onsite and the operations management necessary to get the installers onto the site with a docket of information that enables the installation and commissioning of an electrified portal.

Time is the governing factor to consider, material cost of the integration components made up from terminal stripping and relays and timers is negligible when compared to the cost of manpower to do the work.

The DoorLink package can be as simple as putting the base board onto a surface and adding connector points that equal the quantity of wire coming and going from the board. Make the connections to link power and control to the devices using the “link” features and hard wire connections. To make I/O switches and add time control, plug in relays or the TM30 timer module as necessary.

The application illustrated and the total accumulation represents the a List cost of adding the SIP without taking into consideration the burden associated to time required to service the installation phases that have to be taken into consideration.

The samples are produced using Microsoft VISIO and the SHAPES download that is available to Registered Users. The shapes provide dynamic link line connections that make schematic drawing easy, even for the novice.

Making the proper connection links is the challenge and this is where experience and expertise in low volt applications becomes relevant to making the SIP28 work as the integration module.

What is a SIP (System Integration Point)
and what solution do they provide?

Back to the Top

Having a System Integration Point is not a mandate to any portal installation, but it will definitely provide a base to facilitate an orderly method of producing a documented application instruction that can be followed by any or all installers associated to the installation. The same document also supports the “As Built” aspect often asked for in specification documents.

The real purpose for developing and introducing the SIP box is associated to resolving the particular issue of installation cost control over connecting electrified devices installed into the portal. The door and hardware industry is a supply only service. The devices they provide are expected to satisfy the functional requirement and provide code compliance, if they are connected (integrated) correctly. The execution services are usually provided by other firms who specialize in access and egress system application or in many instances this work is a part of the Division 16 or 26 (Electrical) contract.

Regardless of who provides the execution service the participants have to cost the on-site work to be performed. When there is a cluster of operational devices and possible door automation coupled to an access system, or a group of systems such as infant abduction, wander control and asset monitoring, that all interact with the door operation - integration connection issues have to be resolved in order for the function to be realized. Not to be overlooked, if the installers are bringing their own expertise and using device manufacturers supplied instructions they will also have to be conversant with the applicable building code and fire system integration to insure compliance when they set up the physical “Sequence of Operation”. The “Sequence of Operation” information is another whole area of instruction that is often left to the whims of the installer—until occupancy requires modifications to suit the occupants operational needs.

A thought for consideration as the return visit to make the necessary modifications that the users now understand they need are usually not incorporated into original estimating cost. Bringing the same installer back into the portal for this remedial work can make it necessary to strip the original setup and start from scratch because there in not a document or a consistent setup to any schematic document to work with.

Two example applications are illustrated. Type “A” with a SIP and type “B” without. The various configuration scenarios that can be presented are numerous and the intent here is to understand that the conduit runs have to terminate to some point in order to enable integration. I have purposely avoided the use of local power supply as the integration should not take place in the power supply enclosure or the ADO header unless they have been designed to perform the service.

Most power products are UL Labeled for use and the Label does not support added components.

It is obvious that six plus conduits in illustration “B” have to interconnect or intersect at some point to enable all of the devices associated to the portal operations the ability to be integrated. Where would that point occur?

Application

One (1) pair of aluminum doors with magnetic locks + card access + retraction exit devices + pull station + infant abduction + low volt power.

Devices & Wire Connections required:

2	magnetic lock power (2 x 2)
2	magnetic lock status monitoring (2 x 2)
1	pull station (2 x 2)
2	exit devices (2 x 2)
1	access system connection I/O (4)
1	infant abduction connection I/O (2)

I/O = input / output

Wire Connections:

Allowing 0.6hr. for each termination, the total time allocated for 22 connections is 3.6 hours or half a day. This takes into consideration orientation and the setup time necessary to do the actual connections and test the application.

The connection time allocated is 3.6 hours. A time that from experience is more than ample to make the device connections to a pre-labeled terminal board. Add the total time cost and the material cost of the SIP interface package together and the cost for material/labor is established. Needless to say there are additional values to be considered to complete a portal application including the pre-work required to assemble the SIP components and create the hookup instruction. All of this is processed work assumed to be performed off-site in a controlled environment using CAD systems to develop the hookup instruction and physical integration assemblies that are manufactured with a defined cost.

The bottom line is what is the portal integration cost and how is it calculated to a defined set of components as compared to the “make-it-up” as we do it scenario? My experience and calculations indicate it is less expensive to provide a manufactured solution into the process because it is a known factor. It also has a part number that cost can be assigned to and most importantly it has documentation continuity from the last install and any service technician can service it tomorrow or in the future.

Installation continuity enables real cost control.
