Bell System Power Supplies, Relays and Lock Timers

This page lists the Bell System power supplies, batteries, relays and lock timer modules sold for Bell door entry and access control systems. Choose the model code from the drop-down. Bell lists the PS4A as the power supply in its 900 series, Bellissimo, Bellini, CS106, CS109, Bellcode and Bellprox kits. Bell says standby and boxed power supply units are also available.

Bell's accessories brochure describes the PS4A as a wall-mounting, fused, regulated 12V DC power supply rated at 4 Amps, for use on all Bell systems and for powering high current door release mechanisms. Bell's current range page gives a nominal output of 13.8V DC at 4 Amp and describes it as a double insulated, fused unit included in both audio and colour video door entry systems.

Choosing the right option

Bell's 900 series, Bellissimo, Bellini, CS106, CS109, Bellcode and Bellprox kits already include a PS4A, so a separate one is for a replacement or an added device. Bell notes that a PS4A may be needed for the FB31 flashing beacon, depending on distance. The 640 and 840 are listed for 12V DC standby and backup power. Relays are listed by voltage: 88 for 12V AC, 89 for 12V DC and 90 for 24 volt. Choose LT88 or HT88 for a lock timer.

Common questions

Is the PS4A a 12V or a 13.8V power supply?

Bell's accessories brochure and price list describe the PS4A as a 12V DC 4 Amp power supply. Bell's current range page gives a nominal output of 13.8V DC at 4 Amp. Both describe a wall-mounting, fused unit. The two sources also give different dimensions, so check the label of a unit you are replacing.

Do I need a PS4A with a Bell kit?

Bell lists a PS4A in its 900 series, Bellissimo, Bellini, CS106, CS109, Bellcode and Bellprox kits, so those kits already have one. A separate PS4A is useful as a replacement, and Bell says one may be needed for the FB31 flashing beacon, depending on distance.

Can the PS4A power a lock release?

Bell's accessories brochure says the PS4A is for use on all Bell systems and for powering high current door release mechanisms. Bell's sources do not list the current each lock release draws, so check the release and any other devices against the 4 Amp rating before you connect them.
