TTR-04CW-24 Electromechanical Tripod Turnstile

If the barrier arms do not reset to home position after the start of rotation within  
5 seconds, the RC panel starts generating audio signals. It stops signaling when the 
turnstile gets back to the reset state. 

9.3  Operation with the built-in SPS 

In case of the AC mains failure the turnstile remains in operation and turns to the SPS built 
into the CU. When operating with the SPS, the 

“Battery” 

indicator on the CU is on. The 

signal 

“Pwr failure”

, notifying of the AC mains failure, is transmitted to the CU 

“ACS”

connector. There will be intermittent indication (with blinking interval of 0.5 seconds) on the 
LED indication display of the turnstile housing and on the RC 
At the SPS battery discharging up to the level of 11 V, the 

“Battery”

 indicator starts 

blinking (becomes dim for short time periods) warning about the discharge. The signal 

“Bat failure”

 generates at the CU 

“ACS”

 connector

. 

At the battery discharging up to the level of 10.4 V, the turnstile turns to the “Always 
closed” mode; the LED indication display is out; the blinking mode of the 

“Battery”

indicator and of the red indicator on the RC changes to infrequent flashes. 
In the emergency mode the turnstile can be locked and unlocked only with the mechanical 
release key (10) (Fig. 1).  
When the AC mains is restored, the turnstile returns to normal operation from the AC 
mains. The built-in SPS battery will recharge automatically if the 

“Battery”

 toggle switch is 

in the 

Internal 

position. 

Attention! 

Operation time with the built-in battery is no less than 4 hours in the “Always closed” 
operating mode or 1,000 passages provided that the battery is fully charged.  
The CU SPS contains a lead-acid battery, which is not recommended to be stored 
for a long time without recharging. For recharging during the storage period the CU 
must be switched on for 6 – 12 hours every 8 months (every 2 months when stored 
at ambient temperature above +30°C). The sequence of actions is given in 
Clause 9.1. There is no need to connect the turnstile housing and the RC to the CU 
at that.
