Description

A Potter PS40 low pressure indicator with SPDT contacts. It watches a sprinkler system's pressure and signals the alarm panel if it falls below the set point — which is how a slow leak, a partially closed valve or a failed supply is caught long before there is a fire to expose it. The single changeover contact suits a straightforward low-pressure signal; the two-contact version is used where high and low are signalled separately.
