Guardian AP275-700C1D1 Series Electric Alarm Units w/ Strobe Light and Horn for Class 1, Division 1 Environments

Application: Alarm units serve two important functions when installed in conjunction with emergency eyewash and shower equipment. First, alarms serve to alert facility personnel that an accident has occurred and that assistance to the user may be required. Second, alarms deter unintended or malicious operation of the emergency equipment. For this reason, they are advisable in schools and other areas where the possibility of vandalism is present. Alarms are activated by a flow switch that senses the movement of water in the supply line when the safety unit is activated. Once activated, the bright strobe light flashes and the horn sounds loudly. The strobe light is ideal for areas with high noise levels or where there is high ambient light.

Hazardous Environment: This unit is designed for Class 1, Division 1 hazardous environments where flammable liquids or gases exist during normal operating conditions.

Installation: These units are designed for use with combination safety stations, and can be mounted on either the vertical pipe of the station or on a wall adjacent to the unit. 120 volt, 0.28 amp electrical supply is required.

Visual Signal: Explosion-proof amber strobe light with shatter-resistant lens. Peak candle power of 2,000,000 and flash rate of 60 FPM.

Audible Signal: The weatherproof horn delivers a distinctive, urgent signal. The volume is preset at 103 db at 10 feet. An adjustment screw on the front of the horn allows adjustment of output sound level.

Flow Switch: The AP275-700C1D1 features a 1-1/4" IPS single pole, double throw waterproof flow switch for installation in water supply line to emergency unit. The switch senses the flow of water when either the eyewash or shower is activated. The flow switch must be installed with the tee fitting in the horizontal position, flow switch body in the vertical position, and at least 6" from the closest fitting. The direction of flow is marked on the switch body.

AP275-705C1D1 Option: This is the same as AP275-700C1D1 but includes a double pole, double throw flow switch for connection to a monitoring system. When the emergency unit is actuated, the strobe light and alarm horn activate and an electrical signal is sent to a remote monitoring location.
