Model 6510/COV/SR in addition to the sounder incorporates a SPDT alarm output for remote monitoring. The 6510/COV/S Anti-Tamper Alarm Cover consists of a clear, tamper proof, super tough polycarbonate shield and frame that fits over the 6510-S35 Emergency Pull Station. When utilizing the 6510/COV/S a local alarm sounds when the clear plastic cover is lifted to gain access to the Emergency pull handle for door release. A piercing alarm sounds which is field selectable for 95 dB or 105 dB . Immediate attention is drawn to the area and a prankster will either run or be caught. When the cover is lifted, the horn will sound until the cover is lowered back into the closed position. The 6510/COV/S and /SR covers can operate independently from a standard 9-volt battery or may be powered remotely with 12/24 VDC. The 6510/COV/SR comes with remote wiring capability. The 6510/COV/S has the same capability by utilizing the optional 65-6319 wiring harness. The 6510/COV/SR with Piezo sounder includes a relay with SPDT contacts which is energized whenever the cover sounder is activated by lifting. This output can be used to alert other remote systems. When used with the 6510-S35xCS, the on-board SPDT relay can be used to activate the optional built-in xCS sounder of the pull station. This will cause both sounders to activate while the cover is lifted. If the pull handle is operated, the optional pull station sounder will continue to sound, even if the plastic cover is closed, requiring authorized personnel to respond and reset the handle on the 6510-S35xCS pull station.
