                                          Models SG6551A, SG6552
                                          Single Station, One & Two Point Annunciators

                                          Model SG6552 AnnunciatorModels SG6551A and SG6552 are general service single station annunciators housed in wall mountable thermoplastic enclosures intended for indoor use only. They are typically used with regulator, cylinder manifold or changeover systems in combination with pressure switches to alert the user of product depletion. The annunciators can be configured to operate with either normally opened or normally closed pressure switch contacts.

                                          Model SG6551A is a single point annunciator designed to work with a cylinder regulator or manifold system configured with one pressure switch. Model SG6552 is a two-point annunciator that provides operating status for both left and right banks when installed with a changeover incorporating two pressure switches.

                                          Model SG6551A AnnunicatorThe annunciators provide both an audible alarm and visual indication of pressure switch activation. When cylinder pressure is depleted to a user-selectable predetermined level, the contacts on a pressure switch activate the audible alarm and the red alarm lamp corresponding to the empty bank (pressure switch) illuminates. A reset button located on the front panel silences the audible alarm, while the red alarm lamp remains lit until the gas supply is re-pressurized and the pressure switch returns to the reset position. A green lamp confirms that power ison and the supply pressure is adequate for normal operation.

                                          Both models contain a set of relay contacts for use to control a device that can be activated by a normally open or closed switch such as a telephone dialer, external buzzer, light or another alarm monitoring system. Connections to the annunciator are made through circular male input and output connectors. A 3-foot long input cable is supplied with the annunciator when purchased with an ASGE pressure control system for local connection. A 3 foot long input cable with flying lead ends is supplied when purchased separate or when installed for remote connection with customer supplied cabling.
