Main Control Module

LSS-2382

Placed at a strategic location desired by the customer, this module is considered the "Base module" for any system. All other modules can be added to the base to expand the system functionality.

 

  • Uses a Class C high-security "sidewinder" key to arm and disarm the room interlock. 
  • Contains two dry contacts that can interlock up to two lasers or shutters.
  • Displays the three operational states of the room interlock.
  • 24VDC system power is introduced at this module and distributed to all add-on modules through the main interlock cable.

 

One Main Control Module is required in each room.

(Prior to the introduction of this module, a system would utilize the LSS-2381 Room Interlock Control Module and LSS-2384 Local Interlock Module together to serve a similar function.  That option is still available to our clients when preferred, but it lacks the key lockout feature.)

Laser Safety Systems presently carries 25 different key combinations in-house and will work with our clients to ensure each lab in a facility is uniquely keyed.  If a facility has more than 25 labs, we can order additional key switches in up to 5000 unique combinations.

Laser Warning Module

LSS-2380

Provides a visual indication of the three laser interlock states:

"Crashed," "Safe," and "Armed".

 

  • Normally placed outside entryway.
  • Uses hidden text backlit by LED.
  • Warning triangle can display a solid or a strobe effect.
  • Meets warning requirement of ANSI-Z136.1-2014

Emergency Crash Module

LSS-2383

Placed at strategic locations desired by the customer, often at interior of entryway, and/or at laser table.

 

  • Allows a rapid shutdown of the room interlock and all connected lasers or shutters.
  • Back lit with highly visible red LED when room interlock is armed.

Local Interlock Module

LSS-2384

While many customers needs are met with the two dry interlock contacts provided in the LSS-2382 Main Control Module, some customers have more lasers or shutters and require additional dry contacts, which are provided by this secondary module.

 

  • Placed at strategic locations desired by the customer, this module contains two additional dry relay contacts that can interlock a laser or shutter.
  • Displays the armed and disarmed operational states of the room interlock and local relay.
  • This was a required module in every system prior to the introduction of the LSS-2382 Main Control Module because this module was where 24VDC was introduced to the system and the laser interlock contacts left the system.

Non-Defeatable Door/Curtain Monitor

LSS-2387 KIT

Kit contains Monitor Module and LSS2306-12 Magnetic Door Sensor containing two proximity switches.

 

  • Stainless-steel armored cable on door sensor prevents tampering.
  • Hidden text illuminates to show "Closed" state which satisfies room interlock.
  • 2387B option: provides two form C relay contacts for general use that activate when the room is armed.

Defeatable Access Control Kit

LSS-2388 KIT

Kit contains all components necessary to allow controlled access to or from the laser area by authorized laser personnel.

  • Monitored door or curtain can be opened when bypass timer is activated.  Timer cancels after door/curtain closure.
  • Hidden text on Main Module displays the three interlock states and "access" light.
  • Main Module and Keypad produce system tones for arming, disarming, and access.
  • System self-check performed during each door opening.

Highlights of the LSS2388 System:

  • Controller utilizes our exclusive and proprietary Intelligent Access Timing to control pre-access, access, and post-access.

 

  • Controller has Post-Access automatic cancellation.

 

  • Controller has "Stuck" exit button error handling.

  • Controller can drive 24V Magnetic Lock (LSS2305) or a 24V Electric Strike.

 

  • Controller can accept an override signal from an existing facility card reader access entry system.

 

  • Controller has provision to tie into the building Fire Alarm contacts.

Curtain Defeatable Access Control Kit

LSS-2388EZ KIT

A lower cost alternative to the normal LSS-2388.  The "EZ" version has been simplified for curtain applications.  It does not have inputs for motion detector, Fire Alarm, or Card reader, nor does it have outputs for electric strike or maglock or auxilliary relay.  It is a "bare bones" defeatable access controller that simply watches the curtain limit switch and allows passage of qualified laser workers who enter the proper credentials.  System will trip if access protocol is not followed.

Room Interlock Control Module

LSS-2381

Prior to introduction of the LSS-2382 Main Control Module with lockout key, this module was the primary means of arming/disarming the room interlock.  This module is still very useful in large lab spaces that have several individual laser stations where it is used as a secondary means to arm/disarm the room. 

 

  • If the key on the Main Control module is in the "arm" position, this module is active to arm, re-arm, or disarm the room.
  • If the Main Control key is in the "Locked Off" position, this module cannot arm the room.
  • Displays the three interlock states.
  • This module, combined with the LSS-2384 Local Interlock Module, can still be used in lieu of the LSS-2382 Main Control Module.

System Accessories

laser power supply

System Power Supply
Part # UL24V

This UL Listed Power Supply provides a safe low-voltage (24VDC) at up to 1 amp for powering the interlock system.  Our system is very efficient; a single wall-wart power supply can feed a system with multiple door interlock modules, warning modules, and laser relay modules.  If you are concerned about the power budget for a large system, you need not worry.  Laser Safety Systems will calculate the total load of all desired modules to verify your system will meet the allowable power budget.

cable roll

Main Interlock Cable
Part # 8CUL

Sold by the foot, this UL Listed plenum-rated cable is delivered in a spooled length desired by the customer.  The cable is 8-conductor 22AWG stranded with 8 distinct wire colors that match the colors on the schematic diagrams we provide with each system.

Door/Curtain Monitor Switch
Part # LSS2306-12

One switch is included with the LSS2387 and LSS2388 Access Monitor and Control Kits.  When doors have more than one leaf, an additional monitor switch is needed.

Contains two magnetically sensitive reed relays for redundant monitoring of the door or curtain closure status.

Comes with 12 inches of stainless-steel armored flex cable.  Longer lengths up to 20 feet are available by special order.  Standard contacts are both normally open (NO) and will close in the presence of the magnet.  Contacts can be special ordered in NC-NC, NC-NO configurations as well as the standard NO-NO.

400lb Magnetic Door Lock and Mounting Hardware
Part # LSS2305

Specifically designed to run with low current draw on the existing 24V interlock system when driven by our LSS2388 Defeatable Access Control Kit.

Maximum of two magnetically locked doors per system.

The benefits of extra security must be weighed against the complexity of NFPA codes compliance, so we often recommend against magnetically locking lab spaces.  Please call to discuss before considering purchase.

interlock mounting

Hellermann-Tyton Surface Track, Boxes, and Fittings

Low-Voltage surface raceway is used to route and protect the cable when in-wall mounting is not feasible.  It is manufactured from a cleanroom compatible UL-rated 94 V-0 PVC.

Features a superior "peel & stick" adhesive for installation without any drilling or screwing into the wall.

Compatible with an office or cleanroom environment.  Industrial settings will likely require conventional metal conduit and boxes.
