+BS - this terminal is for connection with an outdoor back up siren. There is a positive potential supplied by this terminal
when the alarm output relay is not switched on.
C, NC and NO terminals are over switching dry contacts for alarm output relay. The maximum load is 1A/60V. The
function of this relay is programmable for different alarm types (using the [∗] [6] installer programming mode).
Power:
+12V, GND - back up voltage output for optional devices (motion detectors, telephone dialers etc.). There are two pairs
of these terminals on the board, both of them are connected together. Maximum current consumption can be 500mA all
together. The +12V output is protected by a FU2 (1.6A) fuse.
15VAC - these terminals are for A.C. power supply connection. Use a transformer with 15VAC output (min. 20VA), or you
can use the Jablotron PSU-10 adapter. This input is protected by a FU1 (1.6A) fuse. Do not switch the power on before
the installation is finished!
ACCU. - these terminals (+/-) are ready to connect to a back-up battery 12V. Size from 1.2Ah to 40Ah can be used. In
normal operating mode the control panel charges the battery. Battery input is protected by a FU3 (3.15A) fuse. Do not
connect the battery before the installation is finished!
Keypad: There are three EXT.KEYBOARD terminals to connect to external keypads model H-915K (or other optional
H-915 device with serial communication). Use three wires to connect the A,B and C control panel terminals with
corresponding A,B and C terminals in the keypad. The maximum length of keypad cable should not exceed 50 meters. If
you use multiple keypads (a maximum of 5 can be used) connect all of them in parallel. Check carefully that you have
connected corresponding wires before you turn on the power to the control panel. (The built-in keypad on the H-915C
model is connected via INT.KEY connector.)
Control panel TAMPER: There is a tamper switch to protect the housing of the control panel. If you have only the
H-915B (main board) don't forget to install the attached tamper switch in the housing.
Procedure for Turning on the Power:
Make a short connection of the RESET link on the board with a jumper. Connect the back up battery and A.C. power
supply. Wait 2 seconds and remove the reset jumper. Close the housing of the control panel (connect front panel - only
model H-915C).
The control panel will reset to the factory default settings automatically and then will perform a self test. When finished, it
will be in the installer programming mode. (Press [#] to enter standby).
Operation
There are three levels of operation in the H-915: STANDBY, USER PROGRAMMING and INSTALLER
PROGRAMMING.
The STANDBY mode is the basic working mode of the control panel. It is ready for arming control. The system can be
directed to perform other functions such as zone bypassing, displaying alarm memory and entering programming level by
using one of the various [∗] commands described below. In STANDBY mode, the zone lights indicate the triggering of
zones, or alarm memory with a slow blinking..
MASTER CODE
A default master code 1234 is programmed into the H-915 at the factory. The master code is used for arming control as
other access codes, but only the master code can be used for entering the user programming level ([∗] [5] command) and
for bypassing zones ([∗] [8] command).
The master code can be reprogrammed by the user, but it can not be removed.
