Program Hundreds of Schedules for 2 Relays

Create comprehensive automatic schedules for almost any N.O. or N.C. relay device with the Seco-Larm Enforcer Annual Timer Module. The timer has two Form C relays, allowing you to program two devices independently to operate on weekly, daily, or hourly schedules throughout the year. It's perfect for a variety of applications, including security, lighting control, climate control, and access control.

  • Schedules weekly, daily, or hourly events for two relays
  • Stores up to 99 events for each relay (198 total)
  • Relays operate independently or in tandem
  • Backlit LCD screen makes programming easy
  • Full backup options ensure reliable operation

Advanced Scheduling Options for Precise Control

The Annual Timer Module features an alphanumeric backlit LCD screen and a few simple buttons to make programming easy. Each relay can we programmed with up to 99 scheduled events (198 total), and five different event types are available to choose from: Disable, ON, OFF, Shunt, or Momentary (1~99 seconds). Each event can be scheduled to repeat hourly, daily, or weekly. This block programming lets you easily repeat events on consecutive days throughout an entire year. You can also program up to 20 holidays to disable the timer on specific days, either a single day or the same day every year.

While the two relays can operate independently, you also have the option of programming them to operate simultaneously by setting the timer to "tandem mode". The timer also lets you override the schedule without hassle anytime.

Timer Features:

  • Two N.O. or N.C. Form C relays (10A @ 24VDC)
  • Allows manual operation of relays without event programming
  • First-person-in function interrupts the timer's normal operation
  • Supports one egress input per relay (two total)
  • Can be set for Standard or Daylight Saving Time
  • Compensates for leap years

Reliable Backups for Programming & Power

Designed to provide reliable scheduling all year round, the timer is powered by a 12/24 VDC/VAC power supply (sold separately) and supports an external backup battery (sold separately). It even has a built-in clock backup battery, plus a built-in battery charger to ensure that your external backup battery is always ready to kick in at a moment's notice in case of a power outage.

Additionally, the timer has EEPROM memory to retain your programming data during a power failure. Data is also password protected, so unauthorized users will not be able to change your schedules without permission.
