Bell LT88 Lock Timer Module

Bell LT88 Lock Timer Module is a multi-function lock timer module designed to control the duration of an electronic door release or other switching devices. This hardware acts as a bridge between the entry panel and the lock, providing an adjustable period of activity to ensure the door remains unlocked long enough for a visitor to enter after being granted access.

The unit is designed for internal wall mounting, typically housed within a protected electrical cupboard or alongside the system power supply unit. It can be triggered by a momentary voltage-free switch or a 12V voltage source from a door entry telephone. This module is ideally suited for installations using standard electric strikes or magnetic locks that require a specific timed release window rather than a simple momentary pulse.

Features

• Adjustable timer potentiometer allows installers to set the lock release duration between 2 and 25 seconds to suit the specific requirements of the building entrance.
• Flexible power circuitry supports operation from either 12V AC or 12V DC sources, making it compatible with a wide range of Bell analogue entry systems.
• Dual-mode trigger logic permits activation from both standard push-to-exit buttons and electronic call signals from internal handsets.
