Part # LSS2380 Laser Warning Module

The Laser Warning Module provides both audible and visual indication of the present interlock state. It is microprocessor controlled to enhance the ability to communicate information to laser workers.

The module can clearly indicate three different interlock states:

Normal safe state (ready to arm) - high intensity green LED's lit solid
Crashed safe state - high intensity green LED's flashing
Laser ON - high Power Luxeon LED strobes behind the international laser warning symbol

The audible warning enunciates during a change of state: A rising frequency tone indicates the state is changing to a level of higher safety concern. A dropping frequency tone indicates the state is changing to safer state.

Part # LSS-2381 Interlock Control Module

The Interlock Control Module is the primary means of arming and disarming the laser interlock. One or more interlock control modules can be placed anywhere within a single laser area to control the state of the interlock.

The "PUSH TO DISARM" button will always take precedence over a request to arm the system. (All crash switches also override ability to arm the system.)

The "PUSH TO ARM" and "PUSH TO DISARM" momentary pushbutton switches are illuminated with high brightness LED's. The illuminated button provides a local indication of the interlock state.

The "PUSH TO DISARM" button is the preferred method of securing the system for normal shutdowns. Following best practice, the activation of emergency stop switches should be reserved for emergency situations and periodic system testing only.

Part # LSS-2383 Emergency Crash Module

The EMERGENCY CRASH MODULE is a safety device specified in ANSI Z136.1-2007 section 4.3.10.2.1. The module can be placed in a location quickly accessible to the laser workers where it is intended to be used for emergency deactivation of the laser or laser shutter to reduce the output levels at or below the applicable MPE.

The module has priority over all interlock controls. Multiple modules may exist on the system

The switch is a maintained mushroom push-lock, turn-reset type Emergency Stop switch with LED backlit illumination. The LED illuminates red when the room interlock is in the "set" condition and is highly visible over a wide area.

Part # LSS-2384 Laser / Shutter Interface Module

The Laser / Shutter Interface Module contains the safety relay and contacts for interface to the laser and/or safety shutter mechanism.

Each module provides two sets of dry contacts for control of two laser or shutter interlocks.

The module has a built-in time delay function that delays the permissive signal for 10 seconds after the interlock system is energized. This delay, in conjunction with the audible warning given when the interlock is set, ensures the laser startup meets the requirements of ANSI Z136.1-2007.

The high intensity yellow LED receives power whenever the internal safety relay is powered, providing positive assurance of relay command state.

Part # LSS-2385-A Access Control Module

Laser Safety Systems LLC has taken the monitoring and control functions that have historically been contained in a large central control panel and consolidated them into a microprocessor controlled module that serves both keypad access control and door safety logic functions. This module is included with the LSS-2385 defeatable access control kit.

The Access Control Module and the three accompanying modules; 2385B, 2385C, and 2385D are designed to meet the requirements of ANSI Z136.1-2007 section 4.3.10.2

As is the case with all other modules, the Access Control Module was custom designed from the ground up by Laser Safety Systems. We began with the fundamental assumption that standard "burglar alarm" keypads are not adequately designed for use in safety systems. Our module uses a Shrack SR2M Safety relay for positive control of the interlock state while the microprocessor controls the door switch monitoring, timing, and keypad decoding functions. The microprocessor to safety relay interface utilizes an AC charge-pump safety circuit. In the unlikely event of a microprocessor failure, the charge-pump safety circuit would not receive a refresh signal and would drop the entire room interlock to a safe state.

The module permits authorized laser worker entry into a laser area by controlling the magnetic lock. There are multiple combination sets permitted. This allows temporary codes to be given to qualified students or temporary workers. The code can be changed after the granted access period or if a laser system layout change is made that requires worker retraining.

The control keypad provides tactile and audible feedback of numeric entry. The door opening time is adjustable via keypad entry by using a master code. The module provides an audible "counting" tone at one second intervals to allow personnel to gauge the remaining time available for door opening.

All four modules of the 2385 series are required to properly interlock a door for defeatable controlled access and are included in the LSS-2385 Access control kit. Non-defeatable interlocks are easily accomplished using module LSS2387 below.

Part # LSS-2385-B Magnetic Lock Interface Module

The Magnetic Lock Interface Module is a companion module to the Access Control Module. It serves as the primary input/output wiring location for access point controls. This module also provides an audible enunciation of door activity within the laser area. A laser operator can differentiate between user entry and exit by the tones produced. Upon hearing an entry tone, the laser operator can stop and verify the worker has donned proper laser protective eyewear. This module is included with the LSS-2385 defeatable access control kit.

The module provides connection terminals for:

Door limit switches.
Building fire alarm and/or laser smoke detector contacts.
Push-To-Exit switch (LSS-2385-D)
Door "crash bar" (REX) switches, floor pressure activated exit pad, or motion detector.
Magnetic lock
Outer door Emergency Crash Module (LSS-2385-C)

All crash functions and fire alarm interface inputs break magnetic lock power and take the interlock to a "crashed" safe mode. Request to exit functions utilize failsafe magnetic lock release monitoring circuitry.

Part # LSS-2385-C Outer Door Crash Module

The Outer Door Crash Module is similar in appearance to the LSS-2383 Crash module, but is designed specifically as a companion module for the 2885 access controls. This module is included with the LSS-2385 defeatable access control kit.

One set of the trip contacts will break power to the Magnetic lock, while the second set of contacts crashes the interlock.

The Outer Door Crash is required to permit rapid access to the laser area by fire or rescue personnel during emergency conditions.

Some users choose to place a protective "lift to access" cover over this switch to prevent tampering.

Part # LSS-2385-D Exit Request Module

The Exit Request Module is included with the LSS-2385 and LSS-2386B Access Control kits.

The button is pressed to initiate an interlock bypass for exiting the laser area. The large green pushbutton is illuminated from the rear with a high brightness LED for high visibility in a dimly lit environment.

When used with the LSS-2385 kit, the rear illumination is present only when the magnetic lock is energized. This gives the operator a visual indication of the exit command and magnetic lock status. All of our access control kits provide an audible indication of egress as well.

Part # LSS-2387 Door / Curtain Closure Monitor

This monitor module provides a Non-Defeatable Area or Entryway Safety Control in accordance with ANSI Z136.1-2007 Section 4.3.10.2.2

The module is placed beside a door and wired to a door position sensor. The room interlock will crash when the sensor indicates an open condition. A Dual sensor is provided for redundancy.

Although the LSS-2380 series interlock system can accommodate multiple doors with full access controls, a significant savings can be realized by designating a single door for defeatable access and all other doors as emergency ingress / egress with the LSS-2387 Non-defeatable Monitor.

An armored dual magnetic switch is included with the purchase of the LSS-2387 Non-defeatable interlock kit.

Part # LSS-2387B Door / Curtain Closure Monitor

The 2387B is an upgrade that contains a separate relay that is activated during laser operations. This relay has two form C contacts available. Some clients use this relay to disable an electric strike during laser operation. Others use it to drive an external Bi-Lume sign. Of course with two form C contacts, it can do both at once.

Accessory Part # LSS-2305 400# Magnetic Door Lock

The LSS-2305 Magnetic Door Lock is the ideal choice for the LSS-2380 system. It is specified to run with low current draw on the 24 volt wiring. This makes it an ideal lock when multiple doors defeatable doors are used on the interlock system.

This device is included with the purchase of the LSS-2385 Access Control Kit.

(Includes L&Z bracket mounting hardware for open-inward or open-outward door configurations)

Accessory Part # LSS-2306 Magnetic Switches

The LSS-2306 Dual Magnetic Switch is available for door position sensing or monitoring the integrity of a class 1 laser enclosure. Special order cable lengths are available up to 96". The switch is included with the LSS-2385 Access Control Kit with 60 inches of armored cable. It is also included with the LSS-2387 Non-defeatable Access Monitor kit with a 12 inch length armored cable.

Part # LSS-2386B Defeatable Access Monitor Kit with card reader interface

The LSS-2386B provides another method for implementing defeatable access control in accordance with ANSI-Z136.1-2007 section 4.3.10.2.

It is nearly identical to the LSS-2386 shown above except it does not interface to an electronic mortise latch. Instead, it is designed to initiate an interlock override when it receives a voltage pulse from a card reader system. This system is used when card reader access control systems already exist at a facility and the facility is willing to program the card reader to restrict access to laser trained individuals. The interface between the card reader system and the laser interlock system are galvanically isolated by an opto-isolator.

Part # LSS-2384i Laser / Shutter Interface Module

The LSS2384i is another form of our Laser / Shutter Interface Module. This module was designed at the request of a client and provides a latching relay that can be armed and disarmed locally as long as the main interlock is satisfied. This arrangement is ideal for situations where one or more shutters are to be independently opened and closed within a laser controlled area.

The user can connect to one set of Form C dry contacts (common, normally-open, and normally-closed) and control a load up to 6 amps.

The high intensity yellow LED receives power whenever the internal safety relay is powered, providing positive assurance of relay command state.
