Maintenance Switch - This maintenance panel is a key-switch that disconnects actuation circuits in the system to prevent accidental discharge during maintenance operations.

• Two LEDS indicate "SYSTEM ARMED" or "SYSTEM INACTIVE" when the key is inserted and turned. The "SYSTEM INACTIVE" indicator flashes intermittently. The key can only be removed in the armed position.
• The maintenance panel mounts to a 4" junction box and operates on 24VDC.
• The information is silk screened on a 2 gang stainless steel plate.
• It is designed for mounting on the wall to a bell box.
  

Agent Abort Station- The agent abort station provides a temporary manual means for interrupting the agent actuation circuit between the initial alarm and automatic release.

• The panel employs a momentary deadman-type switch which, when pressed, opens the actuator circuit by interrupting electrical current.
• Each switch has (2) LED indicators: "SYSTEM ON" and "SYSTEM ABORTED" which indicate the condition of the system.
• Both switches operate on 24VDC.
• The information is silk-screened on a two Gang stainless steel plate.
• It is designed for mounting on the wall to a bell box.
  

Fan Shutdown - The fan shutdown provides a key switch for overriding the fan shutdown while maintenance is in progress.

• Each fan shutdown has a rotary key lock with settings of normal and bypass.
• The information is silk screened on a 2 gang stainless steel plate.
  
  

Agent Abort Station - The agent abort station provides a mushroom pushbutton switch for aborting the agent release which must be kept pressed until the control panel is reset. If the switch is released before the control panel is reset, then the agent system will enter the discharge mode.

• The information is engraved on a sign attached to a two Gang stainless steel plate.
• It is available in black with white text or red with white text. Other colors are available upon request.
  

Preaction Releasing Function Disable Switch - The preaction releasing function disable switch is a separate enclosure that will be installed adjacent to the pre-action fire alarm control panel, housing key operated disable switches and associated status as described.

• The one key disable switch with a medium security key is silk-screened on a 2 gang stainless steel gang plate. It is mounted on a wire mold box.
• The two, three, and four key switches are enclosed in a red 00.5 enclosure. The door to this enclosure is hinged on the left hand side and secured on the right hand side with a tamper proof latch.
• The window has clear plexiglass covering mylar film with red text on white.
• All key switches shall be keyed alike.
• These key switches shall be arranged to disable their associated pre-action system releasing outputs to enable system testing without activating the pre-action valves.
• The key can only be removed in the normal position.
• Each of the switches shall be provided with two LED indicators, one green and one red, which shall illuminate to indicate normal and disable status of their associated releasing function.

Test switches shall be arranged to:

• Disable their associated functions by opening the appropriate circuit.
• Extinguish the associated green LED; normally lit to indicate normal auxiliary function status
• Illuminate the associated red LED to indicate that the function has been disabled
