JA-154J MS II Bi-directional four-button key fob

The device JA-154J MS II is a component of the JABLOTRON system. It is designed to remotely control a security system, various appliances (utilizing programmable PG outputs) or to trigger panic alarms. The key fob is equipped with optical and acoustic indication. It checks its battery status and indicates when the battery is nearly discharged. The key fob communicates via the Jablotron wireless protocol and is powered by a single power cell. There must be a JA-11xR radio module installed in the control panel for the ability to work with a control panel. The device should be installed by a trained technician with a valid certificate issued by an authorised distributor.

Operation with a multipurpose relay (MPR)

The key fob control can also be enroled to a multipurpose relay of the AC-16x series, to control a relay according to the chosen mode. Each button should be enroled to the MPR with a different mode. Even one key fob can be enroled to multiple MPRs for example with a different function. When you enrol a key fob to the control panel and also to an MPR within its RF range, don´t select the same buttons. After enrol a keyfob to an MPR, follow the installation manual of the MPR.

If the remote key fob is out of the RF range of the radio module or MPR, it doesn´t indicate status change or signal loss.

Locking the keyfob

The key fob buttons can be locked (blocked) against accidental pressing. Locking is disabled by default, pressing any button triggers its function immediately. If the buttons are locked, a control panel command is sent when a button is pressed 2x quickly (2x per 1 s) it is also valid for the panic function.

Caution: When a reaction for pressing buttons (A+B) or (C+D) simultaneously is set (for example a panic alarm or garage door control), it is necessary to mind that the action is performed first, including the appropriate response of the LED (1).

The lock can be activated by simultaneously pressing and holding the pair of buttons (A+B) or (C+D) until the yellow LED (1) starts flashing, usually in 3 s. When the yellow LED (1) is flashing release button B and press it again. Activation of the lock function is performed and confirmed by double flashes of the yellow LED and a double beep. After this confirmation release all buttons.

The lock is deactivated by repeating the procedure above. Deactivation of locking is confirmed by one flash of the yellow LED and one beep.

Acoustic indication

Acoustic indication can be completely disabled. Default is enabled. When any button is pressed it is followed by short acoustic signal according to the table 1.

Caution: When a reaction for pressing buttons (A+B) or (C+D) simultaneously is set (for example a panic alarm or garage door control), it is necessary to mind that the action is performed first, including the appropriate response of the LED (1).

The acoustic indication can be disabled by simultaneously pressing and holding the pair of buttons (A+B) or (C+D) until the yellow LED (1) starts flashing briefly for the second time, usually in 6 s. When the yellow LED (1) flashes a second time release the button (B) or (D) and press it again. The acoustic indication is then disabled and confirmed by flashes of the yellow LED and a one beep. After this confirmation release all buttons.

The acoustic indication can be enabled by repeating the procedure above. Activation is confirmed by a double flash of the yellow LED and a double beep.
