Audio/Visual Alarms
 AP275-705 Combination Strobe Light and Alarm Horn With Weatherproof Switch Assembly
with Remote Sensing
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 flashes and the horn sounds loudly. Strobe lights
are ideal for areas of high ambient light and large spaces.
Installation: Unit is 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: Weatherproof amber strobe light with shatterresistant lens. Peak candle power of 1,400,000 and flash rate
of 65 FPM.
Audible Signal: Weatherproof horn delivers distinctive,
urgent signal. Volume is preset at 100 db at 10 feet. An
adjustment screw on the front of horn allows adjustment of
output sound level.
Flow Switch: 1-1/4" IPS double pole, double throw waterproof
flow switch for installation in water supply line to emergency
unit. Switch senses flow of water when either the eyewash
or shower is activated. Flow switch must be installed with
tee fitting in horizontal position, flow switch body in vertical
position and at least 6" from closest fitting. Direction of flow
is marked on switch body.
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: Unit is fully assembled, wired and factory
tested prior to shipment.
