1. Troubleshooting

Wiring Connections:

Use only the wiring entry at the lower rear of the dase and carefully feed the wires along the underside of the

printed circuit board. Avoid contact between bare conductors, screws or metal parts likely to contact the

printed circuit.

Avoid unnecessary splices and loops within the unit. Check all connections carefully.

See Diagram 6 (for No. 650 or 651) or 9 (for No. 659.6,651-6,65@12EX or 65%12EX).

See Diagrams 8 and 9. Connections should be made in this'ordec

1. Alarm Terminals: To connect a closed circuit protective loop, see Diagram. On "-6" and "-12EX" units con-

nect tamper switch circuitry as desired.

2. Optlonal External LED: Connect as shown in Diagram. Also cut the YELLOW jumper on the PC board. Note:

The side of the LED that is not connected to the EXT LED terminal may be connected directly to the DC

source if the run is shorter than from the detector (and if, on No. 650 or 651 units, a control signal is also

used). OBSERVE POLARITY!

3; Control Signal Terminals and Optlons: See OPTIONAL OPERATING MODES. If one of the options is to be

selected, run the necessary lead(s) between the detector(s) and the main control and cut the necessary

jumpers.

4. a. (Nos. 856 and 851 Only): 8.5V.AC Terminals: Connect only the No. 1319 Transformer (supplied to these ter-

minals and plug it into a lPOV.AC outlet that is ON for 25 hours a day. Do not substitute-a different

transformer or improper operation or equipment damage may result. Make certain that the outlet cannot

accidently be turned OFF, so that the No. 650 or 651's built-in standby battery remains charged. The tab

provided on the transformer MUST be used to secure it in place with the outlet cover mounting screw.

Caution: No more than one unit may be connected to the transformer.

WARNING: IF A NO. 1320 TRANSFORMER IS USED, IT WILL DAMAGE THE UNIT!

b. (NOS. 859-8 and 851-6 Only) 6V.DC Terminals Connect these terminals to a 6V.DC source that can provide

40 mA continuously. Observe polarity! Continuous auxiliary capacities for some typical controls are:

No. 1021,402l:

400 mA

No. 4060

: 500'mA

No. 1022

: 15ClmA

No. 330R-25,34ClR-25: 250 mA

No. 3023

: 350mA

No. 332R-50,342R-503' 750 mA

No. 1024

: 2WmA

No. 1025

: 220mA

,!--I

c. (Nos. 85912EX, 65%12EX Only) 12V.DC Terminals: Connekt these terminals to a 12V.DC source that can

provide 30 mA continuously. Observe polarity! Continuous auxiliary capacities for some typical controls

are:

No. 1021-12,4021-12: 400 mA

No. 1025.12,1025EX12:

220 mA

No. 1022-12

: 300 mA

No. 4060.12,406OEU : 500 mA

No. 1023.12

: 550 mA

No. 4090

: 500 mA

5. (Nos. 850 and 851 Only) Battery Lead: Disconnect the unit's BROWN battery lead from the STORAGE POST

on the PC board and connect. it to the + V POST (see Diagram 6). If unit is removed from service for any

reason, BROWN lead must be replaced on STORAGE POST to prevent damage to battery (damage will not

result from normal power outage&.

OPTIONAL aPERATIONAL MODES:

As shipped from Ademco, each detector's LED and relay will function together, at all times, regardless of

whether the main protectjve system control is ARMED or DISARMED. While motion is detected, the LED will

light and the relay contacts will transfer.

When used with a control that can provide a suitable switched voltage to the detector's CONTROL SIGNAL

TERMINAL to signal whether the control is ARMED or DISARMED, the detector can be programmed (by cutting

various combinations of jumpers on the unit's PC board) to provide optional modes of operation as described

in this section.

Switched Voltage for CONTROL SIGNAL Terminal:

CAUTION: Before cutting jumpers, make sure that the control can provide the proper switched voltage

Signal

to the + CONTROL SIGNAL TERMINAL, as shown in the following table:
