Maintaining/Modifying the Call Point Station
During the working life of the station, it should require little or no maintenance. The non-metallic front and rear glass
reinforced polyester (GRP) housings will resist attack by most acids, alkalis, and chemicals and is as resistant to
concentrated acids and alkalis. The front faceplates are of the same material with an acrylic color overcoat. However, if
abnormal or unusual environment conditions occur due to plant damage or accident, etc., visual inspection of the Call
Point station is recommended. Replacement front faceplates are available if a need arises.
Cleaning the Enclosure
The housing/faceplate enclosure should be cleaned periodically with a damp cloth to maintain the legibility of all labels,
icons, and optional LED output. While cleaning, if it is noticed that any part of the station is damaged, it must be replaced
to maintain the functional integrity of the device. Reference the service/accessory parts section of this manual to do so.
Replacing the Break Glass Panel (CP-BG units)
To replace a broken glass panel on the station:
CUTTING HAZARD: Safety gloves are required when accessing the internal front chamber with a broken glass panel in
order to prevent wounds.
1.
Carefully remove the front faceplate to access the front chamber. Caution should be taken, as sharp glass pieces
may be evident, which may result in wounds.
2.
Remove and carefully discard the remaining panel pieces from the front chamber and any that may have fallen
outside the chamber/station.

3.
Position the replacement glass panel at an angle as shown in the following illustration with its top edge placed
against the three return bias springs. Along the bottom edge, place your thumb at the dual black triangles on
either side. Applying pressure to the panel with the both thumbs, push upward toward the three springs—enough
to wedge the glass panel next to the activation indicator’s cam surface and into the two corner bosses holding the
panel in place. The panel should now be constrained so that it does not push itself outward.
