Protectowire Fire Control Systems - Graphic Annunciator

Protectowire Fire Detection System

Graphic Display Panel

The PLD Series Graphic Annunciators, provide easy identification and location of fire and other system related events on a custom floor plan display. The graphic display helps to pinpoint alarms quickly, since no time is wasted in deciphering written labels. Light emitting diodes (LED’s) provide individual remote indication of the system’s status and specific zone alarm, trouble or supervisory indications.

The PLD Series Annunciators are designed for use with Protectowire ACR-1600 and FS2000 Series Fire Control Panels. The Annunciator uses 24VDC operating power from the Protectowire Fire Control Panel, and will utilize the Control Panel’s standby batteries during loss to normal power. The ACR-1600 Series Control Panels, provide a high-going output signal from the Control Panel’s lamp drive circuit to activate the corresponding annunciator LED (or LED’s) behind the graphic display window. In FS2000 Series Panels, annunciator signaling is initiated through individual relay contacts or special annunciator interface module(s), which must be ordered as part of the Control Panel.

The PLD Series Annunciators are housed in surface mounted NEMA-1 enclosures. The backlit graphic display panel is mounted in a heavy duty brushed aluminum frame behind a non-glare plexiglas front panel designed to protect the artwork and LED indicators. The assembly is of "dead-front" construction,with no exposed screws or hinges.

The Annunciator’s surface mounted NEMA-1 enclosures are available in five standard sizes, and may be flush mounted when necessary by installing a separately ordered flush trim ring.

Weatherproof Models

The PLD Series Graphic Annunciators are also available in weather-proof enclosures which are constructed to NEMA-4 standards. These units,which are designated by the PWT model numbers, are housed in a rugged 16 gauge steel enclosure, dip primed and finished in a crinkly taupe enamel. The door has a continuous 1½ inch close-cell neoprene gasket, and the annunciator window opening is sealed by using the Scotch VHB Joining System.
