Bell (BSX16) 9-16 Station Single Door Entry Control Unit

Bell (BSX16) 9-16 Station Single Door Entry Control Unit

The system can cater for up to 63 telephones and up to three entrances.

Each system includes: Tradesmen/Service entry, a fire-switch input, battery standby facility and timed lock outputs as standard. The central exchange unit with diagnostic LED’s simplifies maintenance and any part can easily be exchanged with readily available spares.

Control units are available from a basic 8 station control unit (BSX8) and then in multiples of 8 up to a maximum of 64 (BSX64)

BSX (Bell System Exchange) and DAX Digital Isolating Door Entry Systems:

The BSX and DAX door entry systems are designed to overcome a common problem experienced in local authority and public housing where door entry systems are subject to vandalism from visitors and tenants. These systems operate on the Line Isolation principle which has two advantages over common-wired systems:

• Any malicious damage sustained to an individual telephone or its associated cable will not affect the operation of the rest of the system.
• The telephone conversation between the tenant and the caller is totally private.

Each system includes Tradesmen/Service entry, a fire-switch input, battery standby facility and timed fail secure and fail safe lock outputs as standard. The central exchange unit with diagnostic LED’s simplifies maintenance and any part is easily exchanged with readily available spares.

The BSX control equipment is housed in a secure lockable steel IP55 rated cabinet and can include the following:

• 9-16 Station (Single)
• Isolating fused PCB removable connectors for the telephones.
• A model TS2000-BST 7 day quartz reserve time clock for trades access.
• Regulated PSU with isolation switch.
• A control PCB for each entrance providing timed outputs for door releases (failsafe and fail secure), output tones and inputs for fire switches and trades buttons.
• A 12V 7A/H battery when battery standby is specified.
• Optional access control e.g. Proximity controllers.

Telephones: Any of our DC type telephones may be used with the BSX exchange. Each telephone connected to the BSX control will have ‘privacy of speech’ due to the line isolation. To achieve full \'line-isolation\', the telephones must be individually cabled directly to the control unit. The standard model 801 telephones can be used for economy but the model BS-LX is highly recommended due to its added functions.

Front door panels: The model VRP and model LCP panels are recommended for use with the BSX system due to their resistance to vandalism.

Reassurance tone: A reassurance to the visitor that a call has been made and to indicate when the lock release has been operated.
