General Information about Bell SPA door entry intercom panels

Panels 1 to 10 buttons

They are manufactured from 3 mm brushed anodised aluminium with an integral grill that protects the speech unit and complements the surface back box. The grill has fixings on the rear to firmly secure a model 61 speech unit.

A single push-button with integral nameplate is provided for each station including an optional Tradesmans button. This push-button has a versatile design whereby pressure from any part of the nameplate will initiate a call. The nameplate can easily be removed from the front for replacement or amendment of the name or number on the paper insert (included with each button).

Optional backlighting can be achieved by fitting a model SPA-LAMP lamp unit to each push-button.

Panels above 10 buttons

These panels are manufactured from 4mm brushed anodised aluminium and are available in even numbers and for flush-fitting only.

A single push-button is provided for each station including an optional Tradesmans button. A nameplate is positioned adjacent to the pushbuttons. Optional backlighting can be achieved by fitting festoon lamp units to the back-box; specify model 37 holder and model 36 bulb.

The back box is manufactured from Zintec, a coated steel material that prevents tarnishing and rusting. The panel is attached to the back box by means of vandal resistant bolts (model 38) requiring a special tool (model 39) for their removal. These bolts and one special tool are supplied with each panel.
