Manual Call Points

A Break Glass Call Point is a device which enables personnel to raise the alarm by breaking the frangible element on the fascia. They should be mounted 1.4m from the floor and sited where they can be easily seen. Manual Call Points should be sited on the floor landings of stairways and at exits to open air. It should be noted that Call Points should be fitted on the floor side of an access door to a staircase so the floor of origin is indicated at the Control Panel. Extra points should be sited, where necessary, so that the greatest travel distance from any point in the building to the nearest call point does not exceed 30m. A greater number of Call Points may be needed in high risk areas or if the occupants are likely to be slow in movement. Flameproof call points are available, also handle operated points for use in areas where broken glass may cause a hazard.

Points to consider

• Open circuit, closed circuit, fault monitored circuit
• Surface, flush mounting
• Weatherproof, internal location
• Spare breakable material
• Contact rating suitable for load under alarm conditions
• Special call points for flameproof or special hazard areas
• Hammer for call points with breakable front plates
