Item #: AP275-100

Product Description

The Guardian Equipment AP275-100 electric alarm unit with light and horn is designed for combination safety stations and ensures that others are alerted when the safety shower or eye/face wash is activated. The audio and visual signals ensure immediate coworker response as well as deter malicious activation. With the AP275-105 version, the activation signal can also be sent to a remote monitoring location, making this unit ideal for low-traffic or long travel distance locations as well as laboratories where someone might be working late or alone.

Additional configurations are available for showers (AP280-100) and individual eyewashes (AP285-100); the pricing is the same; please contact us to order.

Features and Options

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 light turns on and the horn sounds loudly.

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. A 120 volt, 0.3 amp electrical supply is required.

Visual Signal: A 14 watt, 1060 lumen LED light with weatherproof, shatter-resistant amber lens and protective metal grid. 

Audible Signal: Weatherproof horn delivers distinctive, urgent signal. The volume is preset at 100 db at 10 feet. An adjustment screw on the front of the horn allows adjustment of the output sound level.

Flow Switch: The AP275-100 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.

AP275-105 Option: This is the same as AP275-100 but includes a double pole, double throw flow switch for connection to a monitoring system. When the emergency unit is actuated, the light and horn activate and an electrical signal is sent to a remote monitoring location.

Mounting: Furnished complete with bracket for mounting on vertical pipe or wall, junction box and 5 foot flexible NEMA 4X cord and receptacle. Electrical connection by others.

Quality Assurance: Each unit is fully assembled, wired and factory tested prior to shipment.

Available Option: An SW silencing switch for the alarm horn. This is convenient when the accident victim has to shower for prolonged periods. The switch is NEMA 4X rated and designed for non-hazardous areas.
