DynaLock 8500 Series Communicating Bathroom Systems
When the bathroom is not occupied all doors are normally closed and unlocked. All switch indicators are not illuminated. Upon entering the bathroom from one of the rooms the occupant presses the inside pushbutton switch to lock all doors. All doors must be closed for locking to occur. Interior and exterior indicators will illuminate red to indicate bathroom is occupied and doors are locked. To unlock doors and exit, occupant presses inside pushbutton again. All indicators will extinguish and all doors will unlock. Depressing outside emergency pushbutton switches, located above or adjacent to each door, will unlock all doors. Outside pushbutton, if used, must be pushed again to reset system to normal use. When connected to a fire panel system all doors will unlock during a fire emergency

DynaLock 8500-2 – Frequently Asked Questions
1) How does the DynaLock 8500-2 bathroom system work for a shared bathroom between two rooms?
The 8500-2 handles a single bathroom with two doors opening off two adjacent rooms. Normally both doors are closed and unlocked with no indicators lit. Once inside, the occupant presses the interior pushbutton and both doors lock together, provided both are closed. Interior and exterior indicators light red to show the bathroom is occupied. Pressing the interior button again unlocks both doors and clears the indicators. It is a privacy interlock, not an access control system, so nobody carries a credential and there is nothing to key.
2) What comes in the DynaLock 8500-2 kit, and what else do I need to buy to finish the job?
The 8500-2 ships as a complete system: two 2511-DSM magnetic locks with door status switches, one 6115A-CB-ILM-24V red interior pushbutton (SPDT, maintained, silk screened LOCKED WHEN LIT, PRESS TO OPERATE), two 6115A-EO-ILM-24V red exterior emergency pushbuttons (SPDT, maintained, silk screened EMERGENCY UNLOCK, OCCUPIED WHEN LIT), one 5725 power supply rated 24VDC at 1.5A, one 500259 interlock logic board, and the 900274-D system wiring diagram. Locks, switches, logic, and power are all in the box. What is not in the box is the wiring itself, the boxes for the pushbuttons, and any mounting brackets your door condition needs (an inswing door, a glass door, or a door with a stop too shallow for the strike plate will want a bracket).
3) Can someone get locked in the bathroom, or locked out in an emergency, with the DynaLock 8500 system?
No. Two independent releases are built in. Each door has an exterior emergency pushbutton mounted above or adjacent to it, and pressing either one unlocks all doors in the system from outside. That exterior button is maintained, so it has to be pressed again to reset the system back to normal operation, which is deliberate: staff know the privacy lock was overridden. The system also has facilities for fire panel connection, and when tied in, all doors unlock during a fire alarm. From the inside, the occupant simply presses the interior button again.
4) Is the DynaLock 8500-2 the right model for a bathroom with three doors?
No. The 8500-2 is the two-door configuration and carries exactly two 2511-DSM maglocks and two exterior emergency pushbuttons, one per door. A bathroom shared by three rooms needs the three-door version of the 8500 Series, which adds the third lock and the third emergency release. The interior button, logic board, and power supply concept stay the same; the door count is what you are specifying.
5) Can a Locknetics RDB4 relay board replace the 500259 interlock logic board in a DynaLock 8500-2 bathroom system?
No. The DynaLock 8500-2 two-door communicating bathroom system is supplied with a 500259 interlock logic board, which carries the sequencing that lets the inside pushbutton lock both doors only when all doors are closed, holds the red occupied indication, and drops all locks on an emergency pushbutton or fire panel input. The Locknetics RDB4 is a 4 output relay distribution board, sold as board only, in the LP series - it distributes relay outputs from a separate controller and does not itself hold interlock logic. Use an RDB4 where you need to fan one control output out to several devices, not where you need the 8500-2 door-to-door interlock behavior.
6) Is the Adams Rite 4605 transformer an alternative to the 5725 power supply that comes with the 8500-2 bathroom system?
They are different kinds of power source. The DynaLock 8500-2 communicating bathroom system ships with a 5725 power supply rated 24VDC at 1.5A, which is what the two 2511-DSM maglocks and the 24V illuminated pushbuttons in the system run on. The Adams Rite 4605 is a regular transformer taking 115 VAC in and putting out 12 or 24 VAC with a 40 volt-amp output - AC output, not filtered DC. A 4605 suits AC-powered strikes and buzzers; the maglocks and logic board in an 8500-2 are fed from its own 24VDC supply.
7) Why use a maglock interlock instead of just putting privacy locksets on the two bathroom doors?
Mechanical privacy locks only lock the door they are on. With a bathroom shared between two rooms, that means the occupant has to walk to each door and throw each thumbturn, and if one gets missed, someone walks in. The 8500 Series links both doors to one interior button, so a single press locks both, and it will not lock at all unless every door is closed. It also gives a lit red indicator on both sides of each door showing occupied, plus an outside emergency release and a fire panel tie-in that a thumbturn cannot offer. The trade is that it is a powered, wired system, so it needs 24VDC at the door and a maglock mounted at each head.
8) Is the DynaLock 8500-2 system suitable for a hotel, dorm, or medical facility, or is it a residential product?
This is commercial hardware. The application it was built for is precisely the shared-bathroom layout you find in hotels with connecting rooms, dorm suites, patient rooms, and assisted living: one bathroom serving two adjacent rooms, where each occupant needs assurance the other door is locked. The electromagnetic locks mean no mechanical latch to wear out under heavy traffic, and staff retain outside release on both doors.
9) What power does the DynaLock 8500-2 need, and can I add more devices to the same supply?
The kit includes a 5725 power supply putting out 24VDC at 1.5A, and the whole system runs at 24 volts DC: both 2511-DSM maglocks, the 500259 logic board, and the illuminated pushbuttons (which are the 24V versions, 6115A-CB-ILM-24V and 6115A-EO-ILM-24V). That 1.5A budget is sized for the two-door system as supplied. If you want to run anything else off it, add up the current draw first rather than assuming headroom.
10) Do the maglocks in the 8500-2 report door position back to the system?
Yes, both locks are 2511-DSM units, and the DSM suffix is the door status switch built into the lock. That is what lets the 500259 interlock logic board refuse to lock unless both doors are actually closed. Without door position sensing, pressing the privacy button on an open door would energize a maglock against nothing and give the occupant a lit red indicator that means nothing.
11) Will the DynaLock 8500-2 work on glass doors or on doors where the maglock will not mount directly to the frame?
The 8500-2 supplies the two 2511-DSM maglocks and the electronics, not door-specific mounting hardware. Glass doors, inswing doors, and headers with insufficient flat surface all need a bracket sourced separately. ZenSupply carries Securitron glass door accessories and the Securitron SAM surface mount kit accessories, including the SWB wood bracket, for exactly those conditions. Confirm your door and frame condition before ordering, because the bracket is what decides whether the lock lands square against the armature.
12) Can I use a request-to-exit kit or latch monitor switch instead of the DynaLock 8500 bathroom system?
No, those solve a different problem. REX and latch monitor kits like the Command Access REX-KIT-ML for ML1-Series mortise locks, the CRSREXKIT-ED for Cal Royal 22/98 and Sargent 80 Series exit devices, the CYREXKIT-ED for Corbin 5000 and Yale 7000 devices, or the SCHLBMKIT-ML latchbolt monitor for Schlage L9000 mortise locks all add a switch to an existing mechanical lock so an access control panel knows the door was used. They do not lock or unlock anything, and none of them link two doors together. The 8500-2 is a complete interlock: it does the locking, the logic, and the occupied indication across both bathroom doors from one button.
13) What do I use to protect the exterior emergency unlock buttons on a bathroom interlock from casual pressing?
A DynaLock 8500-2 two-door communicating bathroom system uses 6115A-EO-ILM-24V red pushbuttons, silk screened EMERGENCY UNLOCK, OCCUPIED WHEN LIT, mounted above or adjacent to each door, and pressing one unlocks all doors until the button is reset. Where that button sits in a corridor a resident or visitor can reach, a Dortronics 6510/COV anti-tamper alarm cover is the accessory made for that job - it is built for Dortronics 6500 series pull stations and 5000 series push buttons, so confirm it fits the button plate you are covering before ordering it against DynaLock hardware.
14) Does a Command Access REX-KIT-ML request to exit kit do the same job as a DynaLock 8500 bathroom system?
No, they solve different problems. The DynaLock 8500-2 is a complete two-door system - two 2511-DSM maglocks with door status switch, interior and exterior illuminated pushbuttons, a 24VDC power supply and an interlock logic board - that gives one bathroom shared by two adjacent rooms privacy by locking and unlocking both doors together from inside. The Command Access REX-KIT-ML is a field installable request to exit kit for ML1-series mortise locks; it adds a switch that signals egress from an existing mechanical mortise lock on a single door. A REX kit gives you a signal, not privacy interlock across two doors.
15) If the bathroom doors are frameless glass instead of wood, what do I need in addition to a DynaLock 8500 system?
The DynaLock 8500-2 two-door communicating bathroom system includes two 2511-DSM maglocks with door status switch, which mount to a header and an armature on the door leaf. A glass leaf has no top rail to through-bolt an armature into, so a glass door mounting accessory is what closes that gap - Securitron Glass Door Accessories are the glass door series parts made for mounting maglock hardware on glass leaves, listed at Grade 2. Confirm the bracket matches the armature footprint of the 2511-DSM before specifying the pair together.
16) I need an audible alert when the bathroom doors are held locked - is the DynaLock 8500-2 the right part?
The DynaLock 8500-2 communicating bathroom system signals occupancy visually: interior and exterior indicators illuminate red when the bathroom is occupied and all doors are locked, and they extinguish when the occupant presses the inside pushbutton again. There is no sounder in the system. Where you want an audible element on the opening, the RCI 914 series is a delayed egress sounder with field-selectable volume output up to 102dB, and the Adams Rite 29-0218 is a piezo electric horn with multi-voltage compatibility that can be driven from an existing output. Both are separate devices wired alongside, not replacements for the 8500-2 interlock.
17) Can I add an audible alarm or a tamper cover to the emergency release buttons on a bathroom interlock system?
Both are common additions and ZenSupply carries them from other brands. For a protective cover over an exterior release, the Dortronics 6510/COV anti-tamper alarm cover is made for 5000 Series push buttons and 6500 Series pull stations. If you want the override to make noise, the RCI 914 Series delayed egress sounder has field-selectable volume up to 102dB, and the Adams Rite 29-0218 piezo electric horn is multi-voltage. None of these are part of the 8500-2 kit and none are DynaLock parts, so they mount as separate devices alongside the system rather than onto the supplied 6115A buttons.
18) I need extra relay outputs or a separate transformer for a maglock interlock. What are the options?
For relay expansion off a low voltage lock system, the Locknetics RDB4 is a four output relay distribution board, sold as board only. For a separate transformer where you need AC rather than the 24VDC supplied with the 8500-2, the Adams Rite 4605 takes 115 VAC in and gives 12 or 24 VAC out at 40 volt-amps. Note the difference before you order: the 8500-2 system runs on 24VDC from its included 5725 supply, so an AC transformer is an addition for other devices on the job, not a substitute for what is in the kit.
19) Do I have to install the exterior emergency buttons on the DynaLock 8500-2, or can I leave them out?
The description treats the outside pushbutton as conditional, wording the reset requirement as applying if it is used. Two 6115A-EO-ILM-24V units are supplied with the two-door system, one intended per door, mounted above or adjacent to the opening. Leaving them off removes the only way to release the doors from outside short of a fire panel signal, which in a hotel or care setting is usually the release staff actually reach for. Wire them.
20) How is the DynaLock 8500-2 ordered? Are there finish or voltage options to specify?
The 8500-2 is ordered as a single packaged system under model 8500-2, with no option axes to select. Voltage is settled at 24VDC by the included 5725 supply and the 24V pushbuttons, and the door count is fixed at two by the model number itself. The specifying decision is which door-count model in the 8500 Series matches the bathroom, not options within the model.
21) What is the difference between the 8500-2 bathroom system and a mortise pin transfer like the RCI 9500/9501?
The DynaLock 8500-2 is an electronic access control system for a shared bathroom - it holds two doors locked together off a 24VDC supply and releases them from an interior button, exterior emergency buttons, or a fire panel connection. The RCI 9500/9501 series is a mortise pin transfer rated 1.5A at 24VAC with a tamper-resistant design; its job is to carry power from the frame into a moving door leaf so a door-mounted electrified device stays energized. If your bathroom doors need power carried into the leaf, a transfer is the piece that does it; it does not lock or unlock anything on its own.
