Four & Eight Point Annunciators
Models SG6554 and SG6558 Annunciators
are typically used in conjunction with pressure switches to provide both an audible alarm and visual indication of pressure switch activation. These annunciators
help prevent costly out-of-gas conditions by continuously monitoring gas pressure in cylinder manifolds or changeover systems.
When cylinder pressure in a manifold is depleted to a user-selectable, predetermined level, the contacts on the pressure switch trigger, thereby activating
the annunciator's audible alarm and red alarm lamp. An "acknowledge" button located on the front panel silences the audible alarm, while the
red alarm lamp remains lit until the manifold is re-pressurized and the pressure switch returns to the normal position. A green lamp confirms that power
is on and the annunciator is ready to alarm. These annunciators feature a built-in SPDT relay for use to control a device such as a telephone dialer, external
buzzer, light or another alarm monitoring system.
The annunciator electronics are panel mounted in a wall mountable enclosure. The eight point annunciator incorporates two four channel electronics wired
together. The wall mountable enclosure is rated for both NEMA Type 12 and Type 13, intended for use indoors primarily to provide a degree of protection
against dust, falling dirt, sprayed water, oil and noncorrosive liquids.
