Bell Timer Module, 10/20 Minute (BCM52G)

A ready-built timer module principally designed for use with an alarm bell or siren, but suitable for use in many other applications.

The unit features both a 10 minute delay and 20 minute cut-off timer, with the option to disable one or the other, ie. instant activation, then 20 minute relay timer operation, or 10 minute delay, then permanent relay operation.

The unit requires a 12V DC supply and the trigger input can be either +ve or -ve.

An on-board relay provides Common, NC and NO contacts for external siren control.

A test link is also provided, which simulates the normal operation of the timer, but with a 6 second delay and a 12 second activation period.

All connections to the board are via screw terminal connectors.

Power Supply: 12V DC
Dims: 64 x 55mm
